Repair Summary
Checked refrigerator for a freezer not cooling properly. Upon arrival, verified the freezer temperature was elevated. Connected HASS and found only a high temperature error code. Performed the weak cooling test, which failed. Inspected the compressor compartment and found no visible oil residue or signs of a refrigerant leak at the lokring connections. No bubbles were detected during the initial inspection. Determined the unit required a filter drier replacement, installation of an access port, and a nitrogen pressure test to locate the leak.
Returned and replaced the filter drier and installed an access port. Began pressure testing the sealed system with nitrogen and, at approximately 225–250 PSI, heard popping noises from inside the cabinet. A louder pop followed, and system pressure began dropping rapidly. Increased the pressure to 350 PSI; however, the system lost nearly 100 PSI within 5 minutes. Removed the evaporator covers and inspected for leaks using a leak detection solution but found no visible bubbles. Based on the rapid pressure loss and internal popping noises, confirmed the refrigerant leak is within the cabinet walls. The refrigerator has an internal cabinet leak and is non-repairable.
