Trane RTU With Faulty Blower Relay! Almost misdiagnosed!

- A PM tech suspected a low refrigerant condition or a restriction in the refrigeration circuit on a Trane Heat Pump RTU that I recently installed a new condenser motor on. After a full diagnosis I determined it to have a faulty blower relay.

Great job and video. Thank you for the knowledge.
I just found you and love ❤️ your content
Thanks for watching!
Good intuition. The board seems like your issue. It's gotta be. The refrigerant looked ok. Nice job
What I was thinking too. Thanks for watching!
Keep going
It looks burnt 🥵 on top 🔝
Yea she does a little
Hello Jeff. Thank you for the videos. Apprentice here and have a RTU doing something odd. The unit will run anywhere for 1-3 hours and then the coil exhaust fans shut off. The compressors run, the fan motor runs, but the motors just shut down. The crazy part is if I turn the unit off, and check fuses and voltage (all read normal) and turn the unit back on, it will run for another 1-3 hours like nothings wrong. I am thinking high limit? Any advice? Thanks in advance.
Maybe a limit. Is there any low ambient controls or fan cycling switch on the unit?
@@JeffsHVACAdventures There is a main disconnect, and a thermostat. Its a York Predator, older kind if I had to guess. Spent an hour looking at it today, before I got put on something else. Will be looking at it again tomorrow, but I am honestly stumped. It just isn't making any sense. But I don't "think" there is a fan cycling switch, I do know the digital thermostat has a "hand" mode where you can force the unit on, but that just turns the blower motor on, not the coil exhaust fans. I have never seen a unit work after for a few hours after a power shutoff, but I fear burning something up. We can't just keep resetting it like that.
You think the contacts are pitted??
Possibly. This call was awhile back. Can’t really remember the particulars of it.
Have you tried the SupcoTradeFox JumperKing
I have not personally used it but a co worker has one and seems to like it.
