I have a RTHB150 that is carrying over at 48% load. Machine runs fine above and below this %.
Has oil been added to the unit lately? Are the evaporator tubes clean? Has refrigerant been added to the unit? Is the EEV working properly?
once loaded had a 4deg approach. Pressures normal, Compressor discharge temp was low and discharge superheat was low but all corrected when machine loaded
When the discharge temp was low and the discharge superheat was low, what was the expansion valve doing and what was it's position. Was it running in extended unloading?
