A week after replacing compressor & drier psi drops -15 low side
Kenmore branded LG french door- freezer on bottom model# #795.71033010 . after replacing compressor & filter dryer it ran fine a week untill the low side pressure dropped to -15psi. Voltage to compressor good. Compressor only pulling .1 amp. No leaks-recovered and left on vacuum pump 45 min. Pressure held - no leaks. Replaced the filter drier again. unit ran fine for 5 days. When it finished a defrost cycle the system low side psi dropped to -15psi. Of course no frost pattern on evap and the condenser was room temp. Could it be the evaporator affected by the heat during defrost? A restriction of some kind in evap? any suggestions greatly appreciated. This is a single evaporator model. Freezer on bottom w/ french door on top.
