Got quoted 650 for new board. Came here to make sure no programming is required. Paid 165 for my board and now I know I can easily slap this on and keep the kids warm. Saved almost 500. Thanks!
One of the best videos I seen on UA-cam! This man is awesome! He explains everything very detailed and precise. Mentioning what cable where it comes from and where is going. Thank you for helping out.
By far the Best video I've seen. Thank you so much for taking your time and putting a great detailed video like this. I dont have enough to pay 300+ to replace my board and thanks to you now I can buy my children school supplies.
Your videos are amazingly clear, educational, and helpful. I don't usually comment, but had to say thank you for this. I happened to have the same unit with a bad circuit board, so I watched several of your troubleshooting & swapping videos. I learned a ton about how my system components operate, and saved a ton of money performing this swap myself!
Great job on video, matches my issue and furnace perfectly. Excellent step by step narrative. Video was in focus, well lit and audio was clear with great tone. Thank you
i guess Im asking the wrong place but does someone know of a method to log back into an Instagram account?? I somehow forgot my login password. I would love any tricks you can offer me
@Keaton Maurice thanks for your reply. I got to the site through google and Im waiting for the hacking stuff atm. I see it takes quite some time so I will reply here later with my results.
Sam... Thank you so much for posting this video... Bought new circuit board only to find my original was obsolete & the replacement was quite different... Would not have got this completed without your video.. Appreciate you!
Overwhelming? Nope, not with your help! Thanks for the simple and straightforward explanation. My board had the dreaded 3 dot light. Tested the pressure switch and it was good. Bought the board and it took 10 minutes and BAM, we have heat.
Great video -- covered everything and so straight forward -- watched this vid as I replaced my control board -- furnace working as it should -- thanks!!!!
Thanks so much! Gave me the confidence to try this and saved me $1200 off one quote. Had a bit of an issue plugging the door switch into the EAC by mistake but looked at the wiring diagram and figured it out
Thanks Sam super helpful video. My blower works fine on fan only (and I think heat), but after ~10m on AC it starts and stops the fan repeatedly. The AC unit in the back keeps running, it is only the blower that is starting and stopping, so I suspect it is the board. This video helped me understand a lot better. Hopefully all the connectors are the same as my replacement part didn’t have adapters
Thank you for your video! I have the exact same control board. As a matter of fact, the vent itself looks same as well. I also have the exact same problem with power. I am going to replace the control board, but with the exact same model. I will just need to move 1 cable at a time, which is going to make the process even easier.
I've watched my fair share of "do it your self" videos. A lot of them have corny intros, elongated introductions, repetitive explanations, etc causing you to skip ahead to try to find the 2 minutes of the 30 minute video that will help you. NOT THIS ONE THOUGH, This video was GREAT! Straight to the point. Pronunciation and solid camera work go a long way! Keep it up
Hi Sam, I am so glad I found your channel. I happen to have the same exact furnace as you. Because of you I was able to diagnose my control board was not giving 120v to my blower. I did the bypass as you showed and the blower kicked right on. Thanks dude!
Great video i didnt start to get confused until close to the end when u changed the last nuetral for , and some of the old connectors that connected to the new ones instead of the board. But then it started making sense to why they gave you those new plugs to plug it into 😂 i feel like i could replace my own curcuit board with this video and some patience lol. It can get overwhelming quickly
When it comes to main systems of our house, I rely on professionals esp. involving gas or electrical systems. I don't wanna blow up my house. But this video is great for people who have a knack for it.
THANKS SAM! i thumbed it, i got a carrier 5 yrs old under parts warranty not labor. 2 tstats, but the 1st floor stat when in off position, the blower will come in for a minute every 15mins for no reason, like its 'hung up'. i switch tstats face plates not the base, no help. turn unit off 30mins, no help, should i replace entire tstat or circuit board (which i heard )? thanks!
Got quoted $1,400 for a new board install, along with $400 for a new capacitor. Ordered a replacement of both on Amazon ($160 for board, $10 for capacitor, WITH tax) and it took me, all in all, 15 minutes to install. Thing is humming along nicely. Lesson learned: if you think that car parts and installations are marked up, let me introduce you to my friend Mr. HVAC. When your markup is 10x-20x the cost of the part, plus less than 20 minutes of labor, there's something seriously wrong.
Yes thank you . you gave me a refreshers course of my soldering electrical class i took i On connecting componets to a circut board except now i know how to connect the board to the equipment
Thanks for the video. We just changed the circuit board on our own. It took us less than $70 and 15mins to fix our furnace. And our mechanic company A1 wanted to charge $1050 to do the job on top of $150 we’ve paid. In fact, they wanted us to get a new furnace by saying it does not worth to fix it while our furnace is only 16 yrs old and overall still great shape. Shitty business practices
Hey! Great video. Liked and subscribed. I got 2 quotes $6000.00 & $8,000.00 to replace my A/C system. Was told the controller was toast. My system will run and cool, only issue is the fan stays on. Possible bad relay on controller? Anyway, I ordered a new control board for $150.00 and will swap it out. If it works, I guess I get to save at least $5,850.00. Thanks for posting this video and breaking down the one by one wire swap.
Sam I have a little different scenario. I had voltage at all the proper places on my thermostat strip. But I did not have power from neutral at the board and the terminal marked cool on the blower section of the board. I did have power in and out of my transformer 120 on the primary side in 27 volts on the secondary side........,.....THEN.... I got a board off of eBay, It was said to be a board from scratch and dent and it was tested. However when I hook that board up (I did it one wire at a time plus I studied the schematic. Now with this board I have no voltage to my thermostat strip at all nominal 24 volts. I also have no power out of terminal S1 or S2 that is supposed to go to the primary high voltage side of the transformer. Of course, consequently I have no power out of the low voltage windings of the transformer now. However if I power the transformer positive wire black, from the D1 terminal on the board then I get power to the primary and secondary side of my transformer, and also power to my thermostat strip and all the proper places. In other words between R and common and between yellow and common and between green and common. I have no power between white and common, however I am not calling for heat I am only calling for AC in this instance. Does does this sound like my board from eBay is also inoperative? This is what I've come up with..... After all I have power into the board at D1 from my door safety switch (and before someone asks yes, the door switch is zip tied closed) but again I have no power out of the board to the primary side of the transformer, and of course coincidentally no power out of the secondary side of the transformer, with transformer connected to terminal S1 or S2. To recap I do have power in at terminal D1 but no power out at terminal S1 or S2. (Looking at the back of the board terminal S1 and S2 are a common hot) Hope I've explained this properly, again my question is do you think my board from eBay is also bad? Oh I forgot to mention the original board had water damage from an overflowing condensed drain pan. My drain is probably clogged I will tend to that at a later time.
My technician replaced a new control board but when I look at the wiring on the control board the wires from the blower for the speed are neither connected to Heat nor Cool. But my furnace turns on.. wondering if he wired the control board wrong.
Been watching all of your videos, thank you so much! I'm not getting any low voltage reading from the wires going into my thermostat (thermostat is blank) so I went to my furnace and took a reading at the board for RW, RY, etc., and only get 1.3 vac. The fuse, transformer, drain, breaker, etc., all checked out fine. Do you think I have a bad board? The fan turns on when I plug in the furnace but I can't turn it off since I can't get the thermostat to work. Help please, thank you!
Is it possible that the new board will look different than the existing board? I can’t seem to find a board on line that looks exactly like mine. A few indicate that they are upgraded and that it will fit Coleman but it looks different.
I change the board. Everything connected perfectly. Went to turn it on blower came on immediately but no power to the thermostat. Would appreciate any help. Thank you.
Your videos are very descriptive. Do you happen to know where i can order a board for a xl80 trane furnace board 50a51-495 the replacement would be CNT2184. Any help would be appreciated.
I just replaced my whole control panel and I'm still not getting any heat. Should I replace the thermostat? It does work when it calls for the blower but no heating is being triggered
hey Sam, this type of board. i had the heat running as normal but when taking reading between Com and Green Wire, No Voltage it says zero. is this normal for this board?
We are having a problem with our older furnace. Its a lincoln gas furnace and we cant replace the board as they dont make replacement boards anymore. Is there a way we can fix it? We cant afford a new heater and are cold
I could use some tips. The heat works fine, and the ac works /sometimes/. We called a guy for it, of course the ac actually worked when he sowed up. He suggested replacing the board (and quoted $750 for that), but maybe due to the intermittence of the function it could be just like a loose connection? I'mma be honest I'm a bit intimidated to get in there. The number of cables doesn't concern me, I build PCs for fun, but pcs typically don't have live high voltage lines. D:
GRADE A WORK SIR,YOU SAVED ME 500 BUCKS WITH THIS VIDEO…NO NEED FOR INSTRUCTIONS,THIS IS LITERALLY STEP BY STEP ADVICE!!!!! SO GRATEFUL FOR YOU AND YOUR VIDEO
Hi Sam, I suspect my furnace control board needs to be replaced. Right now the fan keeps running and no heat, no matter if I set on or off in the thermo, and even if I remove the thermo from the wall, the fan keeps running. I know the thermo is responsible for connecting the red signal line to the green signal line to turn on the fan but if the fan keeps running even when the thermo is unplugged, I wonder if the control board is bad now. My furnace says Bryant and was installed in 2016. I wonder what you think?
@@Jafranmj it turned out that my issue is not related to the board. There is a heat sensor that will prevent the blower from ignition if it is over heated. The sensor is not functioning. You can test that by directly connecting the two wires going to that sensor together to by pass the sensor and see if your furnace ignites. If it does, then you just need to order a sensor which costs 20.
@@zehuazhou3390 My common and W touched and there was little spark. After that the blower hasn't stopped running and no power on thermostat wires. I am guessing something in the board may have been fried. Will have to test with a multi meter once I get one soon.
Hello, is this pretty much the standard procedure for all boards because if it's this easy, I'd rather save the $180 and just got another estimate for $680!

One of the best instructional videos on anything. You didn't skip over the "simple" parts. Got my job done. Thanks so much
Just replaced board on a 25yr old carrier, cant say enough how helpful your video was. Great job!
Like others have stated. One of the most helpful YT videos ever. Saved me a ton of $ and made me much more confident about the project. Thank you
You make everything look so easy. You should be an hvac instructor. Thank you so much for this video. Your awesome!
Great job!!!! I definitely will change the board. Your explanation was easy to follow and understand. Thank you for sharing.

Hi could you help me find a replacement board
Have a question if i have a red light on. my furnance board needs to be replace?
No, the board is good. Read your furnace panel for more information.
that was perfect, thank you
Hello, is this pretty much the standard procedure for all boards because if it's this easy, I'd rather save the $180 and just got another estimate for $680!
thanks for your video
It appears my control board changed! How will I know what goes where?
Thanks this video helped me
Thank you!
Can you please tell me how to figure out the brand of the circuit board I need for my furnace
On the removable door that opens furnace it has a sticker that shows my control board model #
Thank you
I'm doing the same thing, thanks
Nice video I won 250 for the installation
No need to remove the vent.
There are 2 screws in the front at the edge of the furnace.
AC guy wants to charge me $750 for doing this. They're scamming the public.
How about using a 1/4 inch socket so you don't have to waste your time removing the vent in the first place. Otherwise pretty decent video
I change the board. Everything connected perfectly. Went to turn it on blower came on immediately but no power to the thermostat. Would appreciate any help. Thank you.
