""GE refrigerator β not cooling, frost buildup on back wall""
GE Profile PFE28KYNFS in a Pierpont Beach home steps from the water β not cooling properly, frost visible on the back interior wall. Defrost heater had failed, allowing ice to build up on the evaporator coil and block airflow. After defrosting the coil, we replaced the defrost heater assembly and the defrost thermostat, which was also reading out of spec. Also cleaned the condenser coils β significant salt particulate buildup from the harbor-adjacent location. Complete repair in two hours. The coastal proximity means salt air gets into the coil compartment; we explained the maintenance cycle going forward.
