Fault Diagnosis
Hisense Fridge Ice Build-Up
Recurring ice on the back wall or evaporator means the defrost cycle has failed. We repair the heater, bimetal and sensor and clear the drain to stop it returning.
Common causes
- Defrost heater open circuit
- Bimetal thermostat stuck open
- Defrost sensor out of range
- Drain line frozen over
- Door seal leaking moist air
Quick checks you can do
- Note if frost returns after a manual defrost
- Check the door seal
- Look for a blocked drain hole
- Listen for the defrost cycle
When to call a technician
- Ice returns within days
- Coil fully bridged
- Water leaking inside
- Running non-stop
