In this video, I will troubleshoot a frozen evaporator coil. I will go through the testing of the probes, will check to see if the refrigerant is low on charge, and will adjust the TX valve superheat.

To my understanding, if you have to adjust the thermal expansion valve to correct the superheat, means the valve is bad and should be replaced. That means the valve lost its setting for a reason. Is that correct?

The ones I work on don’t have the ports installed to check pressures. Which is the last thing you want to check after amps are read.

If a reach-in cooler has a txv n liquid receiver no solenoid valve do u look for a 10 TD or 20 TD since it's a reach-in ?
