From Houston, TX. You have already helped me out tremendously on keeping my tools sharp with my diagnosis skills. Looking forward to studying your videos every day to become a more skilled tech
I learned from this video but I want to add something. You can disconnect all the t stat wires at the air handler then take a multimeter set to beep when there’s continuity. Then take your leads and go through each tstat wire bundle to see if any wires are shorting to each other. If no short there check the connections on the boards indoor and outdoor the same way. If it’s between common and o it’s most likely the reversing valve coil. Common and yellow could be the contactor or pressure switches. It’s all about knowing where the path of electricity is supposed to go and where it’s not.
I'm from Antioch ,Tennessee , thank you also learned something new about repairing air conditioning units. Thank you for the abundant clarification and knowledge , I am also an official qualified technician for air conditioning and heating. I have been working in the field for 3 years, and I hope to be as skilled as you
Good video, just like you said it, common sense and process of elimination . We all learn something new everyday,but make mistakes when we become over confident. Watching her in southern California !!
This is awesome. Haven’t seen this kind of repair before. We would have quoted out a whole new unit and/or a reversing valve because it’s worth more money. I didn’t even think to just replace the coil, I’m sure there are different things to consider now and not just any 24v coil, i.e physical connections and plug styles, but where to get them per manufacturer. Anyways. Fun watch 🎉
Just a question !!!! Could u of just used the meter to check the contacter coil and reversing vale coil on both of them. Instead of going back and forth !!! Texas
Thank you for watching Thank you for joining and becoming a member Here is my email please send me an email I have a bunch of guides that I want to send you tadfuller1@gmail.com
when you checked the transformer to see if it was sending power i think that part couldve been done quicker if you would have just turned the breaker off and just ohmed out both sides it wouldve saved you a few minutes but i do think you are awesome i just wanted to add that tidbit
Could you just have ohmed out the two coils to see if they are shorted and if so what are the proper ohm reading for a normal coil on both Thanks, love these videos..
When you took the old one out the connector was facing the side. When you put the new one on the connector was facing up and hit the shield until you cut it.
also on new retro RV Coil fitment ....Direct fit parts can be a problem when ordering new hvac parts I have taken the outer medal shell off & slid just the Body in usually works
Awesome video Taddy. Please continue to do more troubleshooting videos. Ex. What would cause a Blower motor on Auto, not run, but when T-Stat is switched to fan ON, the blower comes on? Weak transformer? Etc. thanks.
The transformer’s only purpose is to reduce high voltage to low voltage. Possibly a t stat issue or relay. Multi meter is your best friend when troubleshooting electrical issues. Good luck!
You said make sure there is a inline fuse on the secondary side of the transformer so the fuse gets blown instead of burning up your transformer. But there was a fuse already there that wasn't blown. 🤔
new transformer low volt side Red & green so question is the Hot side LV always shown 1 st red in this case & reading left to right left for Common side green or does it really matter ?? Thanks
Brother I have something to ask you I bought a Mr cool 5 ton inverter heatpump its only a year and a half old my in-laws are old and get cold easy so I did some research and the Mr cool by far had the best reviews for a heat pump that can heat you home easy even when temperature s are 25 below with out using emergency heat so that's why I bought it and after I installed the unit it has ran flawlessly until about a month ago the heat would not come on the ac works fine but heat it does nothing so Im leaning towards the reversing valve i checked the voltage coming to the unit from the air handler it shows 24 v going into the control board of the condenser here's what I want to ask you the coil you found the short in that goes to the reverse valve is that supposed to have 24 v goi😢ng to it also because I have no power at all going to that coil please help if you can
Your equipment, it probably has a two hundred and forty volt, reversing valve But I wouldn't say that the reversing valve is the problem. I would say that I would check the charge. Because in heating mode, if the indoor coil does not reach the recommended temperature, then the indoor fan will not come on If the outdoor unit is coming on, but the indoor unit is not coming on in heating mode. That's what's wrong low charge
Its a 24 volt I know that much I have 24 volts going into the main board but I have nothing coming out of the main control board going to the coils also one of the coils have no resistance and the other one has resistance
What if it turns on but not blowing following Nest thermostat replacement. Cold air blows. Hot air not blowing although compressor works fine. Is it a fuse? I also cleaned out my Trane cage. Learning.
@@TaddyDigest I thought so too at first but Google support for the Nest is not helpful and refute responsibility and state if you have trouble with installation, call the Pro.
That was a reversing valve solenoid? 24 volts actuated? How fortunate. How do you know the reversing valve works? Could have jammed up & burnt up the solenoid. I've had that, so we got a new unit instead.
You are the zohan of the hvac!
Mission Accomplished

I'm glad you like the videos.Thank you for watching.
Thanks we do not have a lot of heat pumps in new jersey... I enjoyed your process am HVAC since 1985.

You are a Teacher. From the videos I watched you are in my top of favorites 😍God bless you sir for what you do to help others.
thanks brother 🙏 💙
I am here to help

You're welcome. Thank you so much for watching. You're gonna do great things
I’m a technician from Port Allen, Louisiana, really enjoy your HVAC knowledge!
Excellent thank you brother
Great video. Thank you for sharing
Good quick easy find ...... process of elimination
Thank you again beautiful job and now I knew how to diagnose my A/C low voltage shorts if they occurs
Very cool
Be sure and check out the other videos I have in the link in the description
Pretty cool, I did learn something. It's always good to watch someone who knows what they are doing.
Awesome Jamie doing this video was worth it if one person learned something
Thank you for sharing this
Yes sometimes never doing this troubleshooting before, makes you wonder where to start first. Super helpful videos! Thanks! Taddy.
Good video, just like you said it, common sense and process of elimination . We all learn something new everyday,but make mistakes when we become over confident. Watching her in southern California !!
Awesome thank you so much for watching
Glad you're here
Great job on improvising to make the reversing valve coil fit! It's never a cut and dry work in our field.
You got that right!
Love troubleshooting ... Good job ... I grew up near Clinton , Tn ... Awesome place to live ...
Awesome Eddy Thank you for watching
A lot more videos coming today
Taddy you are a awesome instructor
thanks 👍 😊
You are awesome my brother, I am learning a lot.
Glad to hear your learning
Very good
Yes, Dave in Madera, Calif. Thanks! You make learning new things very interesting!

Tad you are the man! Awesome hvac man right here!
Great video on finding low voltage short.
Thank you my brother
Thanks so much for the clarification,great job
Just a question !!!! Could u of just used the meter to check the contacter coil and reversing vale coil on both of them. Instead of going back and forth !!! Texas
great show!
thanks brother
here in Fl ...heatpump city.. gotta keep atleast a few dif coils on the van. keep up the good work man, really enjoy the content
Very good video thanks for it.
your welcome 🙏 🤗 ☺️
This channel gonna have me becoming a hvac tech awesome video buddy
That's awesome
Those lil poppers are a good tool to have for low voltage troubleshooting
Great video! Love video’s on low voltage shorts!!!this was easy to understand!!

Thanks for another great video...
Thanks for watching!
Keep up the good work
Could you just have ohmed out the two coils to see if they are shorted and if so what are the proper ohm reading for a normal coil on both Thanks, love these videos..
Great video! How about finding a low voltage short that happens intermittent?
When you took the old one out the connector was facing the side. When you put the new one on the connector was facing up and hit the shield until you cut it.
just noticed that 😳

Pat Kelley....Morris Illinois !
thanks, please do a sequence of operation, thanks again
Florida watching!
Thank You for watching
You d man!…another great video brother!!
Thanks 👍 😊
Awesome video Taddy. Please continue to do more troubleshooting videos. Ex. What would cause a Blower motor on Auto, not run, but when T-Stat is switched to fan ON, the blower comes on? Weak transformer? Etc. thanks.
Your gas furnace has a limit switch that would control the fan. The t-stat controls the A/C blower.
The transformer’s only purpose is to reduce high voltage to low voltage. Possibly a t stat issue or relay. Multi meter is your best friend when troubleshooting electrical issues. Good luck!
Do you use only OEM transformers.or do you go the extra step and put in the ones with an attached breaker on the side / resettable fuse ??
Good job 😊
Thank you
I See You My AC buddy🤪
Teddy would ohmsing out the coil to detect the problem instead of going back and forth trying to see if the fuse pop?
You said make sure there is a inline fuse on the secondary side of the transformer so the fuse gets blown instead of burning up your transformer. But there was a fuse already there that wasn't blown. 🤔
Assuming the unit doesn’t have a fuse; always install one on the transformer’s low voltage side when replacing.
couldnt you test each side of the reversing solenoid coil to ground?
When you were checking the 24v side of the transformer, it looks like the line voltage wasn’t reconnected. At 1:00
It definitely wasn't lol he sold a transformer tho 😂
2:04 😂😂 lmfao I lost it
hahaha
Need some tape around that fuse buddy 4:19
new transformer low volt side Red & green so question is the Hot side LV always shown 1 st red in this case & reading left to right left for Common side green or does it really matter ?? Thanks

Nothing comes on in heat mode only in ac mode will the unit run
Make it look easy 😅
What if it turns on but not blowing following Nest thermostat replacement. Cold air blows. Hot air not blowing although compressor works fine. Is it a fuse? I also cleaned out my Trane cage. Learning.
Sounds like it's a setting on the thermostat or a wiring issue.
@@TaddyDigest I thought so too at first but Google support for the Nest is not helpful and refute responsibility and state if you have trouble with installation, call the Pro.
@@TaddyDigest would i do any damage switching the green C wire (Nest) to the G since it is gas heat? It worked before as-is.
I found bad stepper motor causing fuse popping.
Sometimes pressure switches are the cause.
yup
Taddy: what to do to get number?

You had to “improvise”, 👍
