Refrigerator not cooling due to a failed defrost system
Why it happens here
Older refrigerators in Chenoweth often have defrost heaters and timers that wear out. When the defrost cycle stops working, ice builds on the evaporator coil and blocks airflow to the fridge section. The freezer stays cold while the fridge goes warm, which confuses homeowners.
Our approach
We test the defrost heater, thermostat, and timer with a multimeter before replacing anything. Then we clear the drain line, which is usually clogged with debris, and run a full defrost cycle to confirm the fix. We also check the door gasket while we are in there.
