Refrigerator — symptoms, diagnosis and maintenance
Cooling performance depends on ambient temperature, airflow, door sealing and the refrigeration system. Users should not interfere with the refrigerant circuit.
Safety rule: stop when there is smoke, sparking, a burning smell, electric-shock signs, an active leak, cracked hob glass or suspected gas. Disconnect only when it is safe to do so.
Common symptoms
Refrigerator not cooling
Temperature rises despite operation, or the fresh-food section is warm while the freezer works.
Symptom diagnosisRefrigerator buzzing loudly
Some sounds are normal, but persistent loud buzzing or rubbing should be checked.
Symptom diagnosisWater under refrigerator
A puddle may come from the defrost drain, drip tray, ice maker or water supply.
Symptom diagnosisWhat to check before reporting
- Temperature setting and special modes
- Door sealing and ice build-up
- Ventilation clearances around the appliance
Maintenance
Vacuum ventilation grilles and inspect seals every six months.
Use the frequency stated in the specific model manual. Heavy use may require more frequent maintenance.
