You're very welcome my friend. Be safe

Wicked video man. Would love more like this for other brand rtu with other types of boards.

Amazing job teaching. You have a gift for teaching I can tell. Could you please make a video on how to check the charge on a unit? I’ve watched other people explain it but I still end up confused. You on the other hand explain everything so well. Keep it up

Thank you so much. Excellent video.

fantastic info...as a new tech this was very helpful👍

Good job brother. Thanks again

yes great presentation, thanks

Thank you!

Good stuff thanks

Thanks

Can you short, specific terminals with the proper resistors, to activate each mode separate?

Perfect video

I would recommend holding the test short for a minimum of 8 seconds for best results

Dude you were a lifesaver I have never worked on Trane Now a quick question if you not sure if you’re out of test cycling the power will take you out of test completely

Glad i can help. That's correct. It will also end after a couple hrs on its own. I want to say 2 or 4 hours

Thanks leave the trade better then we found it

Great video Mr Marz We recently took over one site that has this kind of trane units. Tech supports are sucks. I would love to learn more where would I be able to learn about this type of units. Please let me know tech.. Thank you in advance 😊

What about testing the defrost board?

I didn’t understand how that was second stage heating?

Wow my first time seeing a hybrid trane rtu heat pump with gas. Does test mode test defrost function as well?

I believe it does. However I would refer to the operating manual for further information. Thanks again for watching. Hope I helped you in some way. Be sure to subscribe. Many videos to come!!

What about when you have a unit that refuses to go into test mode no matter how long you short the terminals? Including if you short them directly from the back of the LTB terminal board? It just never initiates test mode?

Maybe the screws are rusty. Do it in the back, where the wires are connected

👍👍 on the video, are all the trane test mode like this?

I worked on a Trane RTU and after 3 minutes of running shuts off, any tips?

Can I bypass a phase monitor for testing?

My mame is Afonso Marzano

I can't get one of my Trane units to run in test mode. Any tips on where to check next? I got a no heat call - and so far I do not have power going to my t-stat downstairs. Any help would be appreciated!

Dumb question, but did you check to make sure you have 24v from your transformer? And verify fuse is good? What about the led indicators?

@@charleston51010 Not a dumb question at all. I am getting 24v from the transformer - no LED lights are on - not even a solid green one which is not normal. Also I notice that in "Trane phase monitor" is not showing ON - or FAULT. But I verified that I have all three legs of power. I'm stumped.

Seems like you've got multiple issues. If you have power at the phase monitor and its not powering on, that's easy. Bad Monitor. Do you have 24v at the thermostat? If so, bad thermostat. You probably had a power spike or some bad power that not only took out the phase monitor, but also the stat. Hard to call when I'm not in front of it with a volt meter

May have also lost the board. You're just going to have to keep checking with your meter. Everything that has power and is not functioning properly must likely to a hit from something

Just get a decade box and you can test the individual functions without having to go through all the functions

Give me a link to a decade box that works. All the ones I have tried so far have anywhere from .4 to .72 ohms with all dials off.

How do you know is is cooling mode 1,2, etc, is it written anywhere in the pannel?
