“Not cooling” on a refrigerator does not identify one failed part by itself. Common paths include restricted airflow or dirty filters, a fan/compressor operating problem, sensor, thermostat or control circuitry; the exact model, any error code and measured values determine diagnosis.
Quick answer
“Not cooling” on a refrigerator does not identify one failed part by itself. Common paths include restricted airflow or dirty filters, a fan/compressor operating problem, sensor, thermostat or control circuitry; the exact model, any error code and measured values determine diagnosis.
Likely causes
restricted airflow or dirty filters; a fan/compressor operating problem; sensor, thermostat or control circuitry; refrigerant-circuit performance or door/insulation loss.
Safe checks
Check only user-accessible items such as the socket, valves, door and external hoses; Note any displayed code and the stage of the cycle when the problem begins; Photograph the model/product label and do not dismantle the appliance.
What a technician checks
stored error history and live sensor values where supported; power supply, wiring/connectors and related actuator measurements; functional testing of the relevant mechanical/hydraulic/air circuit.
When to stop using the appliance
Stop using the appliance if water reaches electrical parts, there is a burning smell/smoke, the breaker repeatedly trips, gas is smelled, or the unit overheats abnormally. Isolate power safely and seek professional help.
Stop using the refrigerator for burning smell, smoke, repeated breaker trips or abnormal heat around the plug/compressor. Do not chip ice with sharp tools or open the sealed refrigerant circuit.
