Compressor thermal overload open in heat mode
Hoping you could steer me in the right direction. I'm working on a heat pump in heat mode. Pressures are good while I'm there. Indoor coil clean, blower good. Issue is compressor is shutting off on internal overload, around the time when the outdoor temp drops.
House has two systems. I had to change the outdoor txv on the other system. (Pressures were way off on that one, which made it easy to diagnos. Runs like a champ now)
I'm thinking this system is doing the same thing( faulty TXV- closing too much, starving the compressor, causing it to overheat), just not as pronounced as the other system.
Thanks for the help brothers.
