HVAC Relays (For Beginners)

[@elgkas9928]

You missed your calling. You should have been a teacher at a tech school. The way you present material is direct and to the point making it easy for anyone to understand.

[@JerseyMikeHVAC]

Thanks so much. Always glad to hear my content is effective and helpful.

[@elgkas9928]

@@JerseyMikeHVAC the key is that you explain everything is a concise manner and more importantly, you are not trying to sell or endorse a product. Keep up the great work.

Hay Steve you had no power, how did you heat up anything lol that's fucked up bro ...... lol😂 I just listened to Steve's invention and it's not towards you at all but I just witness a broken heating systems and they really screwed up the commercial funny as shit

[@juanaraujo3793]

The way you explain everything helps me to understand better. you are one of the best. thanks for teach

[@investment-clientrelations2488]

Thank you brother I really love your videos

[@JerseyMikeHVAC]

Awesome. Thank you!

[@yanslabrada8904]

i really love your videos!! can you do a video about crank case heater please, I'm a beginner but i can understen very easy with your videos, thank you !

[@JerseyMikeHVAC]

Thank you. I'll try to include a crack case heater in the upcoming schematic videos I'm doing and maybe even get into diagnostic readings with it.

[@Talentman18]

Thank you!

Ughh just started hvac school and my brain hurts😭Closed and open is so hard for me to understand and i do not know why. I think i over think on how it would affect if i connect 24volts here and why the process=. Bruhh even my explanation makes no sense. Imma need this but in baby steps💀

[@limcus]

Can u give some examples from different circuits using contactors from 24 v? Greetings from Perú

[@manschool4992]

I devour thousands of vids a year. You have a very blue collar way of explaining things that gels with my brain. HVAC is already so complicated. Thanks for keeping things memorable.

[@JerseyMikeHVAC]

No problem! You're welcome.

[@juanaraujo3793]

thank you for sharing all your knowledge.

[@infiniterecursion9550]

My air handler won't turn off unless I turn off the breaker. I wonder if the relay is stuck 🤔

[@JerseyMikeHVAC]

Good possibility.

Great video. Thanks

Great video. Glad I found your channel. Thanks for sharing.

You're welcome. I'm glad you found it too.

I am glad your on youtube seeing the relays operation in my mind was dfficult in my school days.nice .

[@JerseyMikeHVAC]

Thank you. Glad it helped.

Hi Jersey Mike - We have a 1980's AirTemp furnace that works perfectly, except for the blower relay is frequently getting stuck. I think we need to replace it. But where can we find a relay for a forced air furnace that is this old? I'm an engineer and enjoy doing my own repairs, but the local supply house laughed at me and said not worth their time they would only sell me a new furnace for $800 and wouldn't even take the time to help at all or even look at the relay to try and match it up.

[@JerseyMikeHVAC]

Model number? Sometimes a regular relay can be used as a substitute, but I'd like to look at the schematic.

[@jgg204]

@@JerseyMikeHVAC Thanks for the quick reply Jersey Mike! It's an AirTemp Model # 42083C1421 Rev CA, Serial # DC427067 .

[@JerseyMikeHVAC]

I can't find any documentation on it at all, even through Airtemp's archived manual base. Is there a wiring diagram still readable in the unit you can take a pic of and send to me? As well as the relay itself? [e-mail] Other than that, only other thing I can think of is to try to get in touch with Nordyne. They own Airtemp now and could possibly direct you.

[@jgg204]

@@JerseyMikeHVAC Apologize for the hiatus. I have happy news to report. We figured out it was the voltage regulator acting out randomly. Found a new one, did the swap, and everything is working great now!

8:12 - Where did you find that clip?! That’s too funny!

[@Tito-hvac8]

Great explanation. Thanks

This particular relay has bower motor attached to it. As the blower motor has multiple wires for multiple speed. what is the suggested speed for blower motor. For Efficient heating. Considering pressure drops in a duct. This could be irrelevant(out of box)question. you can ignore it if you like.

[@JerseyMikeHVAC]

Typically in heating the lowest blower speed is used to maximize the amount of time the air can absorb heat as it passes through the heat exchanger, which can help keep down cycle times. With problem areas, medium speeds can sometimes be used to push a little more air to weaker vents but that doesn't always help and can sometimes even make things worse in a few cases. Usually, it is either a duct design issue or improper air balancing that blower speeds cannot easily overcome or correct by themselves.
