i would like to know what would happen if both rb and 1k1 are closed because of call for heat and low temperature ??

thank you very much very helpfull

You are the best of all the time brother AN EXCELLENT TEACHER THANKS

I have old thermostat with wires in both o and b. Trying to connect to a nest but confused with separate wires for both b and o. Any help? Or I need to change the entire wiring system?

Super Super video. Now this is the easiest and best way to teach I believe. It is clear and to the point. Thanks

Excellent explanation. I have to install a couple of these on dryers to open air dampers when the dryers are started. Install is going to be a breeze now

Great explanation!!

Your are the best you made so simple i could fix my hvac as home owner much respect

What is that on the ride side with the e/ c/ aux terminal??

Hey Jersey Mike! Can a 15k auxiliary heat strip be wired on one breaker or both breakers have to be wired? In other words can one side be used?

Good

You made this easy to understand, I watched this video because I need to install a safe T switch and I need to identify circuit R. I had drain pipe clog that spilled water to my sheet rock. I want the switch to shutdown the unit for me when I am not home or to avoid water damage.

I subscribed your channel and shared your vedeo

Thank you sir 🙏 I am new in canada 🇨🇦. And sir watching your every vedeo . Thank you for explaining with schematic diagram ❤ awesome

THANKS 🤟😎

after watching a few times i now understand what all the wires do,im just having a tough time wrapping my head around what i can do to install this C adapter for the homeywell T9,i have an okder lennox ac with no Y terminal,my tstat is a 3 wire cooling only so i have R,W and G wires,it tells me in the C adapter manual if i have no Y terminal it wont work for my system,im figuring if i can use another terminal to "fool"it maybe i can get this thing to work,im going to go back and study your video some more thanks

thank you for the video,im trying to hook up a honeywell t9 on my older lennox ac unit and am having a hard time

This is the most intelligent explanation of thermostat and control board wiring. Thank you Sir.

You are an awesome teacher. Thanks for this.

Thank you. This does not have a board. It's a Lennox

Great demonstration

So my blowers are not coming on would I then jump RTG on the thermostat and see if the actual thermostat is bad?

Thankyou jersey mike for cutting all the bullshit and explaining what I need to know from the start.i love you man you saved my ass with my old lady and the landlord.thank you thank you thankyou.everyone this guy is the shiznit.sorry about the language but I do believe it is verifiably warranted.god bless you jersey mike HVAC.

Hey Mike, clever how you put this together, showing what controls voltage flowing where and when. Keep em coming....

Perfect

Hi. Thanks for the video! I do have a quick question... I just finished installing a smart thermostat for my boiler and I connected the thermostat with the R (load) rather than at the end with C. Is there a good practice on that? In your diagram we can see the C from the transformer goes to W of the T-stat. Mine would go to the C of the motor. What's your thoughts?

Hey Mike great video. Have a quick question about nest thermostat with gas boiler two wire only for heat. I have read that if it’s heat only and two wire I shouldn’t need a common wire. Is this true or should I add a plug in transformer any help would be appreciated

Great video!

Thanks Mike. Also there is Interlock schematic for heat strip whenever called for heat fan come on , which is that whole another topic. But anyway appreciate the illustration

Hi Mike, lots of tech I have seen my hvac feild, especially during heat mode they are clueless, I'm always fascinated by old school actual mechanical defrost and bunch of Relays do the defrost board. I barely come across the old heat pump that has these components, is there anyway you can put video on this one please. Thanks

you lose the battle the first time you have to buy the overpriced parts, IF you can get them

Thank you so much for making this video. I am learning a lot about the unit on the roof of my house, trying to understand why it seems like I am getting a high pressure lockout situation.

Why is the common wire taking power to the fan motor? And why is there 120v going to the common terminal on the transformer? I always understood common was ground

Can you pls do a video about mini split troubleshooting not too many out there

That’s some high shit presentation bro thank you

This is awesome...Is there a place I can find schematic on specific model...old Heil in particular.

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

Thank you so much!

Have you ever seen a nest screw up a circuit board?

I just saw a video that breaking Y would cause the fan to stay on squirting the water everywhere

Well done and thank you!
