Im working on a RUUD Model #UPKA036JAZ. in heat mode it kick the high pressure swith. The head pressure is 325psi and the suction pressure is 60psi. i checked both coils both fan motors and capacitors, everything is clean and ruuning smooth. Compressor RLA 14.1 amps outdoor fan 1.3 amps. Everything seems ok, however I ran out of light before i could check temp drops. would you suspect the 4way valve or TEV blockage? I have a buddy who's had the same issue's on the same unit and switched it out. Im going back today around 4 and going to check temp drop across the 4 way, but was wondering if any of you have seen this issue with a ruud HP and what you did to solve it.
