Dude you are the man. I’m a 5 year Hvac tech, installer and maintenance guy. Your videos are hands down the best I’ve ever scene. I do a lot of troubleshooting service work and have learned quite a bit from you. Outstanding work.

[@lucdumouchel3864]

So good. Thanks for your good work. If ever you could show a wiring diagram for this type of sensor, you would make my day.

[@phillipjoy8191]

Good video. I have never seen one of those.35 years ago we use to use a sail switch to detect when the blower was on .Now all your circuit boards have that built in for your cleaners and humidifiers.Enjoy your videos 😜

[@dylandrymond3951]

Well done Craig. Thanks again. 👍👍

[@acservicetechchannel]

Very welcome. Thank you for the support

[@kingcreo2760]

Run in to quite a few of these. Good video.

[@acservicetechchannel]

Thank you for watching!

[@rogerf3622]

I didn’t know they were used in HVAC. Thx.

[@luiselizalde6757]

Really well explained, thanks a lot teacher, I wish you the best, and family as well

[@acservicetechchannel]

Glad to help Luis!

[@sknight0391]

That's a "Load" of good info 😁👍

[@acservicetechchannel]

Very! Thank you for watching!!

[@clarksafg]

Always learning something ..🌡🌨⛈🌤❄🔥

[@acservicetechchannel]

Thank you for supporting!!

[@HfJax]

Can you pls make a video about reversing valve how they work and troubleshoot them

[@jimbola77]

thank you, partner, for sharing! excellent video!.

[@acservicetechchannel]

Glad you enjoyed it!

[@pridemechanical815]

What about when you have a variable speed ECM lower motor? I see in your video it looks like you're using APS c and you are putting the common wire through the sensing relay. For the ECI motor can you simply put one of the hot wires through the sensing relay? I mean it should draw amps and close the sensing relay correct?

I have a question regarding testing the 24 v sensor - does it matter whether the 24 V transformer generates AC or DC?

[@chuckhogan7625]

Based on the troubleshooting example you showed (when not powered by 24v) I assume this unit actually consumes 24v in order to function and operate the relay, and doesn't simply operate through induction. I had hoped to use it without 24v to simply close a circuit (battery powered alarm module) but that does not appear to be feasible. Do you agree?

[@zekenzy6486]

Great Video. What is mean Selenoid in HVAC ? Thank you for sharing ^_^

[@darrelsparkman4382]

Ooover?
