Upon arrival, I found the system producing a 9 degree temperature difference. I checked the refrigerant pressures and found that the suction pressure is running high and that I’m getting liquid refrigerant back at the suction port. I have determined that the TXV has failed and is in the stuck open position. To get this unit to function properly, we will need to replace the TXV. I observed other issues and those are a burnt contactor and and filthy condenser coil. I provided options to address these issues.
