Important Tips for Hisense Models

  • Some models may enter a demo/display mode where cooling is disabled; ensure this is off according to user manual.

Possible Causes

Dirty or blocked condenser coils

How to Identify: Visible dust or debris buildup on coils at back/bottom of fridge; fridge runs constantly without cooling effectively.

Part: Condenser coils

Incorrect temperature settings or demo mode

How to Identify: Control set too warm; fridge displays demo mode where cooling is disabled.

Part: Temperature control / settings

Faulty thermostat or temperature sensor

How to Identify: Fridge cycles incorrectly or not at all; adjusting thermostat has no effect.

Part: Thermostat / sensor

Compressor or compressor relay failure

How to Identify: No humming from compressor, fridge not cooling; clicking sounds from compressor relay.

Part: Compressor / start relay

Damaged or weak door gaskets / seals

How to Identify: Cold air escapes easily; dollar bill pulls out easily; condensation around doors.

Part: Door seals (gaskets)
