So my condenser calls for cooling in when set to heat and vis versa
Thankyou my best breathar all teom welcomed sight ex area welcome all proesgers and procvation es mind drevpelpment life pregres thankyou gues
I’m a seven year hvac experience technician with residential and commercial equipment and I love this video. Thanks for making hvac videos.
Thanks for watching!
This is one of the most informational and easy videos to follow. I’ve been a service tech for 2 years and I still go back and watch videos to keep me refreshed. This video is hands down one of the best. I’m located in south Florida and we had a some cold weather this past winter, and this video alone helped me diagnose a bunch of heating calls. We don’t really get them down here so I’m not always practicing checking heaters
That really is so awesome, thanks a lot!!!
At the age lf 36 I have been in the field for 16 years now, and you by far are one of the greatest instructors that I have come across, I love you channel what you do is top tier
Thank you so much!!!
Thank god for people like HVAC SCHOOL. God is balancing corporate greedy with great UA-cam teachers…thank you so much
Yes Bryan and his team do a great job for our industry!!
Honestly who gives this man a thumbs down.? This a great explanation. I’ve been in the HVAC industry for over 20 years and always learn something new every time I watch his videos .
Should definitely be working as an instructor at an HVAC school. Ide get into the trade if he was my Boss. lol
Probably a plumber 😉
HVAC technicians that don't want to share the good stuff
@@Keeping-It-Real-55 l pp
I agree 100% with you Art. I had a shitload of questions about how a 10kw heat strip was wired and how they operate in general. This guy doing the video was all about educating the novice technician as well as the very experienced tech. Made everything clear and answered all of my questions. Very good information presented at a professional level. No need for other videos...my man has it ALL COVERED. Peace to ya brother.
Thanks big time I am doing my apprentice on the field while I am going to the school at night
Combining that with your videos everything is going well I really appreciate the time and effort that you put in the videos
One more time thanks
Glad to help Luis!
I am six months in my HVAC school and we were just doing this wiring last night and it is SO confusing. You make this look so easy. Jeez I wish I had you as my teacher 😅 you’re so good at what you do. Great video.
this was the most informative and the most helpful out of all the videos i've seen. a sign of true intelligence is when you can break down complicated subjects into simple concepts that are easy to understand. thanks so much!
this guy literally wrote the book on AC
wow, i am a 3 year tech, and in the 3 years of residential service, ive only ran into 3 electric furnaces/heat pumps and i have no idea how they worked, luckily those calls were easy, this video basically did the job for me, its as simple as 1-2-3 haha
Just fixed my heater issue, thanks to your video. Thank you so much
Excellent video to prepare for return HVAC tech repair. Had blower but no heat, aux heat light flashing in unoccupied building after turning temp higher for cold weather. Found the HVAC tech did a maintenance service call weeks ago but failed to insert the power disconnect plug at outside heat pump. Installed disconnect and Heat Pump worked, but concerned if weeks of heat strip only damaged limit switches, fuse or heat strips as blower worked but no hot air prior to reinsertion of power disconnect plug.
Thanks Craig for the info. I'm teaching electric heat right now this semester in college.
Thats awesome Bronchee! Have you checked out my AC book yet? We have teachers using this in schools now, thanks! If you need info, email me at info@acservicetech.com thanks!
Wow awesome! I’ve just replaced that fan control board on a heat pump package unit. Seems like it’s a. Common part. Interesting I didn’t know about letters F and L on the limits. Almost don’t see the electric heaters here in south California. Now after watching this video its clear to me! Thank you Craig. You are the best!
I am glad to help and thanks for your support!
I believe this is the best explanation I’ve seen on UA-cam, thanks a lot.
That's great to hear Sarah, thanks!
Thank alot many tech or maintenance guy don't understand this procedure I hope this clears it up for some thanks.
Thanks Q!
Extremely good explanation and demonstration of electric strip heating circuits
Thanks Duane!
As a newbie to the servicing field this was really helpful.
I run a company and use your videos to help out my newer techs. It saves me a lot of time. You do a great job explaining in detail. However you made one mistake, on the single sequencer (M1,M2,M3,M4) the upper and lower level contacts close at the same time, 1-20 seconds. When you have a dual heat sequencer, 2 side by side or a second sequencer (M5,M6,M7,M8) powering the 3rd and 4th heat strips, the second one will close at the later time of 30-90 seconds. I just wanted to clear that up for newer techs watching this.
Thank you for putting this out there. Helped me T/S my air handler. Found the strip heaters were burned out. 1 question for you or the community here, what would cause 4 strip heaters burn out on a 4 year old air handler?
I have a icp unit recently replaced txv worked great a couple weeks. This morning I found ac running with heat strips on. Unplugged heat strips and now EVAP fan motor runs continuously.
Great info step by step. Going to the field now to tackle the troubleshooting. Thanks for your great video
Lol the way you pulled out that thermal limit switch at 10:22. Great video
The best on UA-cam
Best explanation on earth👍
Not all heroes wear capes.. much love .. thank you for the knowledge
Thank you for your video well explained help me understand how it works
You always have very educational videos. Much appreciation! Keep it up.
Thank you very much!
As a new tech, this video really helps. Great explanation.
Thanks a lot Angel!
This video got me out of a jam today. Thanks!
Very clean, man you got a gift.
done, rewatch if want
Great video. I have to troubleshoot a system strip heater soon. Really helped.
Thank you for the support!
Best video yet on this topic
Thanks Cameron!
No problem. Thank you
Very helpful. Thanks for being clear and concise.
You're welcome!
Very well done video. Not overly slow , you can tell he is assuming some technical abilities
Super Helpful, Thanks 👍🏾
Absolute amazing video i was having trouble doing this in class last night after watching this im sure ill do fine thanks a lot
This training is great for any type of technical work. Thanks
Thanks Craig!
Thank you, really appreciate your time
Always great explanations and videos
thank you for this video, very well explained!
This GUY IS THE BEST!!! I WATCH ALL HIS VIDEO GREAT EDUCATOR...THANK YOU
I would like you to make a video of how wire an air handler with hydronic coil. Ty.
What turns the compressor on and the reversing valve into position for hearing?
Thanks so much. The video is very educational and informative.
This is great information. I have a Trane unit almost identical to this and the fan delay relay was changed out but with a rly2807 that has normally open connector on relay. And in ac relay works fine, but in heat mode the fan will not come on unless thermostat switch fan on. I think someone put the wrong relay on this unit, as you said this system should have a normally closed relay.
absolutely amazing video explanation of the components in a furnace. and how they work. 👍
Well explained 👍 now i fully understand
Thank You Excellent Explanation 👏
Glad it was helpful!
Great video
Thanks my friend
Very good tutorial... not saying I'm 100%, but very well done, & easy listening! J
I appreciate that!
Thanks Craig u make it look easy!
Ha ha thanks Marcus!
Such a great video . Thank you so much .
You are so welcome!
Excellent video as always!!
Thanks a lot!
this looks like straight electric heat, got any videos on a heat strip such as on a Nordyne electric furnace wired into a heat pump such as Rheem or Goodman split system used in mobile homes
Outstanding
Thank you soo much. God bless you
Once again thank you. Awesome video
Thanks Steven!

Hello
On a Goodmen unit as you are showing. Can I run the A/C unit with the heater breaker being turned off.
Enjoyed your post.
Excellent
Thank you so much 😀
Good video, thanks!
Glad you liked it!
I hate heat pumps a lot less since watching your videos.
Good stuff!
Thanks for the visit
great job my friend great job 👏 don't pay those thumb down any mind, they don't like you giving away secrets 😀
Thank you, I will
Video very helpful. Thank you. Keep videos coming
Thanks, will do!
My question is in the MCA and MOCP for 240/208 for unit with electric heat. I always see like for example MCA 56/49 and MOCP 60/50 for 240/208. Wouldn’t the higher voltage mean a smaller breaker? Feel like the voltages or breakers labeled are backwards. FYI I am looking at a Lennox air handler for those numbers, but I see it on Carrier too.
I would need a pic of that to jog my memory on that one. Usually they only have only one per rating but I know what you mean. You could email the pic to info@acservicetech.com thanks!
Goodman package unit coils appear to be getting hot but the air at the vents is like warm at best
Is this compartment a mock up for training? I’ve only had 1/3rd the room for my paws and meter.
Please you are requested to make a video on sdmn6 fieldpiece.
look up acservicetech furnace pressure switch troubleshooting video
On a Carrier FB4CNF036 air handler there isn't a fan control board like you show in the video. All of the wires go into the fan motor. Is the fan control board built into the fan motor assembly?
Speed taps
Excellent video 🤘⚡️🤘
Thanks Nor-Cal! Many people including myself really appreciate what you are doing!
AC Service Tech LLC thanks!
Use continuety tester when testing something that low of ohms so you don't think it's an open circuit. (depending on meter)
curious to know why there is a 7 second delay on the board for G?
Thanks a lot....great explanations
Glad to help abou!
Thank you for the helpful videos. I've run into an issue with my electric furnace that happens atleast once ever couple of days: The thermostat will call for heat, but the furnace never comes on. While testing, the only way i've gotten it to work again is jumping the fan wires (R & G) for a second or two. 5 seconds after I do that, the furnace will kick on again and go off at the specified temperature. Do you know what could be causing this and how to troubleshoot? Last time this happened, jumping R and W did not work.
Great video! Is it possible to accidentally crosswire and have the heat strip activated when the blower is on, but the thermostat heat mode is set to off?
Good information thank you
Thanks a lot Jeffrey!
Can you do a video on a heat strip that has no sequencer and the white wire from the thermostat is connected to the 24 v common on the contactor. I just want to know how it turns on and off. Thank you
Thank you for your video. What is the function of Sequencer in the air-handler? Does it control timing for cooling on and off?
If you wanted to disconnect the emergency heat for a generator, which wire would you break with the low voltage wire coming from the automatic transfer switch for the generator?
Like from indonesia sir
Thanks a lot Trick!
Good video, learn a lot from it. I will subscribed you
Very good, thank you!!!!
Thanks Mauri C!
Do you have a video on heater interlock
Hello, Thanks for informative video. I have quick question - recently, i have replaced my old 5k heat strip with 10k strip and connected all red/black wire as it was on 5k. But, when my unit runs it doesn't seems to be hot enough. Not sure if replacing with 10k did anything so I am not sure if I did something wrong? Please let me know if you can guide me. thanks
