Why your Sub-Zero freezer is not freezing
When a Sub-Zero freezer is not freezing, here's what you'll usually notice: freezer compartment stays above 0°F. Common causes: defrost thermostat, evaporator fan, sealed-system leak. On this platform it's most often sealed-system refrigerant leak. Left unaddressed, food or stock can spoil within hours.
Most likely causes
- Failed temperature sensor
- A clogged defrost drain
- Defrost thermostat or heater failure
- A weak or failing compressor
- Sealed-system refrigerant leak
Known Sub-Zero freezer weak points
- Dual compressor / sealed-system failures
- Evaporator coil frost blocking airflow
- Intermittent ice maker failures
- Control panel/board faults
Quick check — and when it's not DIY
Before you call anyone, listen for the evaporator fan running when the door's closed, since a silent fan is a common first sign. Once you've ruled that out, a fan that's confirmed dead, or ice built up around it, means removing interior panels to reach it — not a quick swap without disassembly experience.
