Great case! I was scammed by a "good" contractor, who told me that I need a new control board. Actually, it's the blockage of the hose to pressure switch. He charged me $600 to replace the board, AND he cleared the blockage of the hose. He wanted to take the old control board away, but I refused. I later on figured out the board was good because I put the old board on and it worked! He never answer my call after that. I also heard that he scammed a lot of people around locally.
They all do it. The HVAC industry is one of the most corrupt out there. Better yet, just call your gas supplier first. Their calls are free and are part of your regular billing. I'm with Atco Gas, they would have cleared the blockage for free.
Yes they all do it SCAM people. One company s technician charged me $300 dollars for a capacitor. Probably goes for $5 dollars and probably didn’t need it. This was during a seasonal maintenance. It’s how much they can scam .
@@timcat1004our gas company doesn’t do any of that. They came out for free and checked that gas was coming to the house. He said they aren’t trained in HVAC but he tried to help. I e done all these steps except the pin. I’m going to try blowing everything out again but with a vacuum or air and see if that does it…
I'mma be honest, I don't even know why this worked for me, but it did. I didn't notice any clogs, but something about performing these steps got my heat back on. Thank you, brother
You're a lifesaver, man. Did everything in this video and it fixed my heater and now it's running like a dream. Saved me money and a headache. Thanks so much.
This was my exact problem. Tube was clean and the switch would open and close. Wiggled a piece of wire into the base, reconnected the tube and started working again. UA-cam to the rescue again.
Thank you Leo. Thought that the pressure switch was the culprit and replacement the remedy, but after watching your video, and clearing the flow path to the pressure switch, Viola! The furnace is operating normally. I literally couldn't have done this without your step-by-step description of the potential causes of the a faulty pressure switch. All for the cost of a paper clip and 20 minutes of my time. Doubly glad for having seen your video, because I now think that even with a new pressure switch in hand, the furnace still would not have fired up. I'm now inspired to do more work myself and clean the fan/blower housing of dust and replace the fault/wear prone parts. Thank you again.
Man you are a life saver!!! It’s 1:45am cold 8 degree Michigan night. I almost gave up and waited for a hvac tech in the morning but saw your video and tried exactly what you said. Thanks brother 🙏🏾
Thankyou for this video. I was getting a similar issue with my furnace this evening. After checking the exhaust vent as that's what several google searches turned up for a probable issue with mine I stumbeled across your video. Took the vaccum lines off, cleaned them and re-installed and the furnace fired right up! Thanks again!!
You are the man! I paid a ton of money last year to a furnace guy who took about five minutes to fix my issue. So when my furnace wouldn’t start this year, I said no way. I found your video, followed the instructions, and boom-it fired right up! Thanks so much!
If the jumper is in place when you turn on the power you will get an error code. The pressure switch must be seen to be contacts open at the start of the sequence. It's actually the first step in the sequence of ignition and it prevents anyone from bypassing the pressure switch which is a safety switch that informs the circuit board that the vent motor is turning and that the venting is free of obstructions. Bypassing the pressure switch will give you one cycle. Once the thermostat is satisfied it will not start again until the bypass is removed. This prevents a wayward technician from killing his customers by trying to be a nice guy by circumventing a safety switch. By inserting a wire in the vent motor port you cleared the rust or scale that was blocking the orifice. Testing a pressure switch should be done with an inline manometer. This will determine if the vent motor is delivering sufficient vacuum to satisfy the pressure switch setting in wc. Very good tutorial for anyone who has a pressure switch error code just be mindful that the pressure switch is a very reliable component and the cause of the problem is usually something else... rusted vent motor blower fins, weak blower motor capacitor, blocked venting, etc.
Thank you for great input and your knowledge! And thank you for being awesome at delivering your knowledge in a professional way! I’m no expert by any means but my fiancé is pregnant and I was trying my best to get some heat 🙏🏼
When we taught this to our students one of the faults we deliberately installed in a furnace was to block the vent motor port much like you encountered. By splicing in a digital manometer the technician can see precisely what pressure the vent motor is delivering to the pressure switch. Testing a pressure switch by sucking on it is not representative of real world conditions. A small tear in the diaphragm can be easily missed as lungs can develop a much stronger vacuum than the vent motor. We stress that while a pressure switch can fail it is a safety and therefore inherently reliable. Safeties usually trip when an underlying condition exists. You demonstrated a very good troubleshooting aptitude and found your problem. Always good to have a happy wife.
Jim thank you for more knowledge! It makes absolute sense to test the switch with a manometer but most people probably don’t even know what it is. You make a very solid point that the lungs can develop more pressure than the switch and some diaphragm issues can be overlooked by this mechanical “test”. And it makes sense that the switches, being a safety device, are reliable units. My thought was that if you don’t hear the clicking, then it’s an indication that the switch is damaged inside more than just a crack in the diaphragm. You bring back great memories of discussing things with my college professors who often elaborated on things in great detail so I could understand, in depth, the concepts and mechanisms. It’s a pleasure to chat with a knowledgeable individual like yourself 🙏🏼 thank you! Happy holidays to you and your family!
December 23,2022 Friday evening at 10:09PM. We have a blizzard in Buffalo. We had electricity but our furnace stopped working. This video saved us! Thank you Thank you Thank you
Wow. This saved me today. Furnace was doing the exact same thing. Followed all the steps here and my surface ignitor finally came back on. No more pressure switch open fault code flashing. Thank you for posting this video. The family is warm again!
I'm so thankful I came across this video. I thought I'd have to replace the igniter, but following your instructions, my heater came on! What a blessing.
Historic sub-zero temps in Denver this week and furnace wouldn't heat and my landlord is out of town. Watched 20 videos and tried lots of basic troubleshooting with no success before coming across this one. 3 min later my furnace is working like a champ. It was all about the clicking!!! Thank you!!!
This here solved my problem and saved me some $$$ that didn't need to be wasted. Thank you so much for the video! The husband wanted to call the heating and air conditioning guy to come and fix the problem but a little digging around youtube saved the day. Thanks again!
Leo - We woke up this morning (Colorado) to 55 degrees in the house. My husband spent 8+ hours troubleshooting everything he could think of. Your video was the fix he (and our family) needed. God Belss you!
Fix works like a dream! Beginning of cold season in nashville tn area when I woke up to very cold house and no heat on a Sunday morning. No idea what was wrong with furnace and getting a repair tech on a weekend is very painful $$$. So found this video which made sense and gave it a try. Ya!! Fixed issue and now got heat! Thank You so much for sharing this tip!
Today, I was able to pull off the hose from my pressure switch and see corrosion or just accumulated dust within the nipple that lead into the furnace. Using a thick needle I was able to clear the obstruction and reattach the hose. The very moment I restarted my furnace the heat came pumping through my house. This video completely helped me save a bunch of money and it literally took me 30 seconds to troubleshoot thanks to you... Seriously - Thank you!
My furnace went out last night, was 55 degrees in the house this morning. I came across your video and fixed my furnace. Thank you for the awesome video!!!!!💥💥💥💯
Leo can't thank you enough brother! That was exactly my problem. The inducer motor nipple was clogged. It's almost 12:30 now and I been freezing my ass off since waking up cold at 6 am trying to figure this out. I'd pretty much given up until I thought about the pressure switch and then I found your video. You are THE MAN! ty so much!
Thank you for doing this video sir. I watched a few other videos but yours was the gamechanger. When you suggested to keep the hose attached to the switch and suck back to hear the clicking. It worked. Much appreciated!
I'll add my thank you's to all the others. Just at dark on a cold Saturday we noticed the house getting cold. I knew it probably wasn't serious but didn't know where to start. Your video was exactly what I needed. I followed the steps, put the hose back on, flipped the switch back on, the flashing code went off and the furnace fired right up. You showed and explained everything perfectly. Thanks so much!
Thank you!! You just saved me $180. I had a guy come by last month and do this for me and it took him all of 10 mins. I am gratified I was able to fix it tonight myself -- I just noticed it wasn't working at 10 pm, so now I wont be freezing overnight. Many thanks!
Thank you! I replaced the flame sensor first, as that was an issue previously. It solved one issue but I got the pressure switch error. Your video was one of the easiest ones that explained how to do it. You're amazing!!
Thank you, Leo! So thankful for people like yourself who take the time to share knowledge to help. This was my problem and it's fixed now, sir! Thank you so very very much! Stay Awesome! David
Again you saved my ass Leo! Furnace was throwing up the code and not running. Took off the hose blew and sucked on it a few times to hear the clicking. Put er back on and voila! Thanks again man! You rock!
As Jim said in the comments, the switch is a crucial safety component and even though it’s working, I’d still replace it with a new unit. It will cost you about $35-40 and you can replace it very easily. Glad that the video was helpful!
I had this error code today. Was afraid that I would need to call for technician. Did what is instructed in this video. Fixed the error code and my furnace is now running. Glad that I found your video. Thank you.
I can not thank you enough! Woke up to a cold house, furnace wouldn’t turn on. Did a little troubleshooting of my own, found my issue, found your video. BAM! Running like a champ again. House is nice and toasty! Thanks so much!
Thank you SO much for this video. Helped me understand more about the furnace's operation and correctly diagnose and fix the issue. You saved me a call the HVAC technician!
Sir, thank you so much for the video. It was exactly what I needed to fix my problem. I was so stressed out thinking I was going to have to pay someone to fix the issue. God bless you❤️
Thank you for showing where to look for the Indicator light and walking us through troubleshooting. I applied your advice and was able to get my furnace working again, thank you for making the video.
Even though they tell you not to do this as it may ruin the bladder in the switch. I did it just like Leo said and it worked! Love saving money and NOT getting hosed for a service call on the weekend! Thanks a bunch Leo!
Leo, you’re a genius! This fixed my problem. After doing a lot of diagnosis this was the last thing I did before calling a technician. Thanks for sharing this information!
I can't believe this worked. So grateful. I was freaking out and was watching many videos on UA-cam. I saw this one and tried it. My Lenox furnace fired right up. Thanks for the video. On my furnace three flashes indicates ( Burner failed to light, or lost flame during heat demand). Not sure what that means, but this did the trick.
Leo, thank you for this! I had the 3 blinking lights and quickly ordered a new pressure switch then found your video, I did your step of cleaning the valve with a pin and that cleared any clog that might have been there. Same as you I could feel a little blockage give way when I slid the pin back and forth. Connected everything back and everything worked perfectly after this quick fix! Going to cancel that pressure switch order now!
Thanx Bro My furnace stopped running early early Sunday morning had the Techs out Sunday and they brought over a used control board and they couldn't fix it they said they'd be back with parts. It's was almost Wednesday and I just got it running right before midnight. I cleaned the ports in - collector box , inducer fan box, burner box . Blew on diaphragms and I got it running . ✌🏼😁
I live in Atlanta and the furnace in my attic doesn't get much work until late in the year and I don't notice that it is not working until it gets really cold. This video got me up and running in about 15 minutes! No need to bypass the pressure switch. Checking the tube for obstruction, exercising the pressure switch diaphragm and inserting a wire in the vent motor port to clear rust or scale was a great idea and seems to cover all the bases when the pressure switch is throwing a code letting you know its stuck in the closed position. If that doesn't work try replacing the pressure switch, they are cheap and easy to replace. If its still not working, checking and potentially changing the capacitor might help. That is the extent of my personal knowledge, if I can't resolve it beyond that, I'm calling a reliable heating and air company and getting a trained technician to help me out. Thank you for the video, the wire in the vent motor port was a new one for me!
this video saved me $100's avoiding a service tech. I thought it was the flame sensor went bad. Ordered a new one and it did not keep burners going. The next step was learned from this video. I took the hose off pressure switch and blew into it to make clicking sound. Once I took hose off the nipple that goes in the inducer motor fan housing. There was a noticeable blockage of crap in the nipple. Took a wire and shoved it in and also blew thru hose into housing. After that, furnace burners kept working and heating the house once again. This video helped troubleshoot my furnace problem!!!!!!
Thank you !! That blowing in the switch thing worked! Tried everything before that and watched a ton of videos and you were the only one that added that. I appreciate you taking the time to make a video!
This seriously worked. Furnace was throwing a pressure switch error, so I took out the old one, blew on the tubes and the switch, used a paperclip to clean out the intake, and the thing fired right up. Thank you sir!
Leo! All I can say is thank you and God bless you. I was about to order a pressure switch, igniter or igniter sensor. Did what you said and the furnace is up and running. Shout out from Ohio!
That was the exact problem with my Lennox ML 180DF furnace. It looked like some old bug bodies were clogging up the port. Thanks for posting up this video!
Awesome video, woke up this morning to a cold house 59 degrees, blowing into the switch was all it took, did not have to go as far as trying to use the paperclip for blockage, service call on a Sunday would have been pricey.
This is such a good video. So many ideas and small fixes that should be done anyway. Helped us heat our house in a matter of like 4 minutes. Thank you so so much!!!
Legend. My heat had failed recently. I even did the initial investigation here showing the error codes and called an HVAC guy who just blamed my smart thermostat. When it failed again I came here and fixed it with your help.
Thank you Brother you saved me from a cold night and a lot of time! I’m pretty handy found my code really fast and tried blowing the tubes but I didn’t know I needed to keep one side on and blow moving the valve! Thanks we fixed it! now my wife and kids can sleep with a heated house in Minnesota!
Seeing comments of people this video has helped, I’ve realized that being able to help someone stay warm in the cold is the greatest reward. Knowing that I was able to help someone I have never seen or know. Happy holidays everyone and best wishes 🙏🏼
I cleaned the flame sensor and bought a new one, still doesn't work .I thought maybe its the ignitor but it's glowing there's just no gas. Then I stumbled into this video. Just what you did, I found one of the nipples is blocked with maybe a gunk or something. I used small nail to push that and cleaned the small hole, put back the hose. I turned the thermostat on, ignition glowed and there's the flame! Thanks lot Leo. Power on!
Thank you for your video. My model was different. And the issue ended up being not in the pressure switch, but water clogging the exhaust from the motor (heavy rain dripped down the pipe and the water was standing in there, creating real pressure issue at the exhaust). But you gave me enough courage to actually get in there, check the pressure switch, and check the other tubes. Thanks again.
Thanks.....this fix worked great for us and our furnace is working great......was just about to call an HVAC repair guy to come out after checking igniter etc and came across your vide......thank you again
Thank you Leo ! Great, to the point video with simple explanation. I was able to get it to work in 5 minutes. (I did not remove the wires). 1) Removed the tube and blew into it, 2) then blew/sucked after connecting the tube to the pressure switch and 3) cleaned the nipple using the pin and connected the tube back. Voila ! few seconds after I turned it on the error is gone and it started working. THANK YOU !

Always watch what they do
I think something like that happened to me because he took the board.Too soon old and too late smart.
They all do it. The HVAC industry is one of the most corrupt out there. Better yet, just call your gas supplier first. Their calls are free and are part of your regular billing. I'm with Atco Gas, they would have cleared the blockage for free.
Yes they all do it SCAM people. One company s technician charged me $300 dollars for a capacitor. Probably goes for $5 dollars and probably didn’t need it. This was during a seasonal maintenance.
It’s how much they can scam .

Heck yea bro. Enjoy the heat! :)
This was my exact problem. Tube was clean and the switch would open and close. Wiggled a piece of wire into the base, reconnected the tube and started working again. UA-cam to the rescue again.
You saved my bacon, brother! This solved our issue. Great video.
Saved me from having to pay for an emergency Sunday hvac call today with this video! Thank you.
Thank you Leo. Thought that the pressure switch was the culprit and replacement the remedy, but after watching your video, and clearing the flow path to the pressure switch, Viola! The furnace is operating normally. I literally couldn't have done this without your step-by-step description of the potential causes of the a faulty pressure switch. All for the cost of a paper clip and 20 minutes of my time. Doubly glad for having seen your video, because I now think that even with a new pressure switch in hand, the furnace still would not have fired up.

Leo, you are still the man. Impressed the hell out of my wife by watching your video. The paperclip operation solved it. Many many thanks.
Mike, you know, happy wife happy life 😁 glad all is well 🙏🏼 all thanks to God. Stay blessed my friend.
Man you are a life saver!!! It’s 1:45am cold 8 degree Michigan night. I almost gave up and waited for a hvac tech in the morning but saw your video and tried exactly what you said. Thanks brother 🙏🏾
Thankyou for this video. I was getting a similar issue with my furnace this evening. After checking the exhaust vent as that's what several google searches turned up for a probable issue with mine I stumbeled across your video. Took the vaccum lines off, cleaned them and re-installed and the furnace fired right up! Thanks again!!
Thank you thank you thank you! Very easy fix that saved us hundreds today! All I needed was a Bobby pin.

If the jumper is in place when you turn on the power you will get an error code. The pressure switch must be seen to be contacts open at the start of the sequence. It's actually the first step in the sequence of ignition and it prevents anyone from bypassing the pressure switch which is a safety switch that informs the circuit board that the vent motor is turning and that the venting is free of obstructions. Bypassing the pressure switch will give you one cycle. Once the thermostat is satisfied it will not start again until the bypass is removed. This prevents a wayward technician from killing his customers by trying to be a nice guy by circumventing a safety switch. By inserting a wire in the vent motor port you cleared the rust or scale that was blocking the orifice.
Testing a pressure switch should be done with an inline manometer. This will determine if the vent motor is delivering sufficient vacuum to satisfy the pressure switch setting in wc.
Very good tutorial for anyone who has a pressure switch error code just be mindful that the pressure switch is a very reliable component and the cause of the problem is usually something else... rusted vent motor blower fins, weak blower motor capacitor, blocked venting, etc.

Can we assume that the flame sensor is on a similar step in the sequence of ignition and you can't just jumper it?

Checking the tube for obstruction, exercising the pressure switch diaphragm and inserting a wire in the vent motor port to clear rust or scale was a great idea and seems to cover all the bases when the pressure switch is throwing a code letting you know its stuck in the closed position. If that doesn't work try replacing the pressure switch, they are cheap and easy to replace. If its still not working, checking and potentially changing the capacitor might help. That is the extent of my personal knowledge, if I can't resolve it beyond that, I'm calling a reliable heating and air company and getting a trained technician to help me out. Thank you for the video, the wire in the vent motor port was a new one for me!
Thanks a ton, friend! ❤
Your detailed step by step procedure of troubleshooting worked for me. There was gunk in the orifice as you showed.
Dude you just saved me at 4 am in freezing cold Chicago. Much love and respect!!!❤❤❤
You are the man. I am literally sitting here right now with a working furnace after watching your video. Thanks man
Thanks, Leo! This fixed my furnace issue and probably saved me a bundle. You're a lifesaver! 👍
Your video is a lifesaver! I blew into the switch, and that fixed the EE1 error code I was having. Saved me a HVAC service call.
this video saved me $100's avoiding a service tech. I thought it was the flame sensor went bad. Ordered a new one and it did not keep burners going. The next step was learned from this video. I took the hose off pressure switch and blew into it to make clicking sound. Once I took hose off the nipple that goes in the inducer motor fan housing. There was a noticeable blockage of crap in the nipple. Took a wire and shoved it in and also blew thru hose into housing. After that, furnace burners kept working and heating the house once again. This video helped troubleshoot my furnace problem!!!!!!
You the man! Just fixed our furnace! ❤
Awesome video! Just fixed my furnace watching this was 52 in my house and a low of 31 coming tonight. Appreciate it!!!
Thank you !! That blowing in the switch thing worked! Tried everything before that and watched a ton of videos and you were the only one that added that. I appreciate you taking the time to make a video!
Thank you so much! I was just about to give up on this repair after a few hours of trouble shooting and your obstruction clearing worked perfectly. 👏
Thank you Leo! I was planning to buy a new switch until I watched your video. It was exactly my problem and I am now up and running! Much appreciated!
This seriously worked. Furnace was throwing a pressure switch error, so I took out the old one, blew on the tubes and the switch, used a paperclip to clean out the intake, and the thing fired right up. Thank you sir!
Leo! All I can say is thank you and God bless you. I was about to order a pressure switch, igniter or igniter sensor. Did what you said and the furnace is up and running. Shout out from Ohio!
Leo, You are the MAN!! A thousand Thank You's for this video! It turned out to be that small hose. I appreciate you!
🙏🏼 I’m sincerely happy that this video helped you! Stay warm and happy holidays 💜
Fellow GA person here. Good job on the presentation!
I was in the middle of doing all this except the Bobby pin at the end to clear it up. Absolutely worked. Thank u sir. 🙏🏻🙏🏻🙏🏻
That was the exact problem with my Lennox ML 180DF furnace. It looked like some old bug bodies were clogging up the port. Thanks for posting up this video!
Awesome video, woke up this morning to a cold house 59 degrees, blowing into the switch was all it took, did not have to go as far as trying to use the paperclip for blockage, service call on a Sunday would have been pricey.
Thank you that fixed my heater unit that was blowing cold air. I followed those steps
This is such a good video. So many ideas and small fixes that should be done anyway. Helped us heat our house in a matter of like 4 minutes. Thank you so so much!!!
Legend. My heat had failed recently. I even did the initial investigation here showing the error codes and called an HVAC guy who just blamed my smart thermostat. When it failed again I came here and fixed it with your help.
Brother, happy to be of help. Enjoy your warm and cozy home :)
I hadn't had heat in almost 2 months. This video saved me. Thank you!
Bro, you just saved my a$$ a whole bunch of $$$. Thank you!!!
Thank you Brother you saved me from a cold night and a lot of time! I’m pretty handy found my code really fast and tried blowing the tubes but I didn’t know I needed to keep one side on and blow moving the valve! Thanks we fixed it! now my wife and kids can sleep with a heated house in Minnesota!
Thank goodness for this. Fixed my issue without the need for a service call! Thank you!
Solved my problem. You are a giant amongst men. Thank you sir!
Seeing comments of people this video has helped, I’ve realized that being able to help someone stay warm in the cold is the greatest reward. Knowing that I was able to help someone I have never seen or know. Happy holidays everyone and best wishes 🙏🏼
Thank you so much for your help! Saved couple hundred dollars by your video!
Thanks my guy got my heat going for free every company I called wanted to charge 145$-180$ a hour
Thanks for simple video that is to the point. Cleared water out of my pressure switch line and it is working great.
Furnace wasn’t putting out warm air the other night and did the paper clip method and worked! Thanks for the video was very helpful
Thanks for the video! Fixed my problem in less than 3 minutes!
That's EXACTLY what it was for me. Thank, Leo! Saved me a bundle.
Thank you, Leo! So happy to have run into your video I fixed my issue! Keep up the great work
I’m so thankful for this video because I followed what you did to solve the 3 flashing red light error code. It worked!!! More power to you, Sir!
Did exactly what you did in your video and it worked perfectly. Thank you so much for making this video and sharing!
Solved my problem! Had to get my suck on for 10 minutes, but the exhaust vent melted out and solved my problem. Thanks so much!!
Looks like video number 8 did the trick! Thank you so much.
I cleaned the flame sensor and bought a new one, still doesn't work .I thought maybe its the ignitor but it's glowing there's just no gas. Then I stumbled into this video. Just what you did, I found one of the nipples is blocked with maybe a gunk or something. I used small nail to push that and cleaned the small hole, put back the hose. I turned the thermostat on, ignition glowed and there's the flame! Thanks lot Leo. Power on!
Thank you for your video. My model was different. And the issue ended up being not in the pressure switch, but water clogging the exhaust from the motor (heavy rain dripped down the pipe and the water was standing in there, creating real pressure issue at the exhaust). But you gave me enough courage to actually get in there, check the pressure switch, and check the other tubes. Thanks again.
Thanks.....this fix worked great for us and our furnace is working great......was just about to call an HVAC repair guy to come out after checking igniter etc and came across your vide......thank you again
Thanks for sharing, Leo. That was my problem and it's now working again.
This worked perfectly. Had some buildup and the pin trick worked like a charm. Thank you!
Thank you thank you thank you ! This was exactly my problem. My family is warm tonight thanks to your video !
This was so helpful thank you!!
Thank you! Fixed my furnace in 10 minutes!
Thank you Leo ! Great, to the point video with simple explanation. I was able to get it to work in 5 minutes. (I did not remove the wires). 1) Removed the tube and blew into it, 2) then blew/sucked after connecting the tube to the pressure switch and 3) cleaned the nipple using the pin and connected the tube back. Voila ! few seconds after I turned it on the error is gone and it started working. THANK YOU !
