How We Repair Your Sub-Zero Freezer
Freezers and blast chillers keep food at or below 0°F, so a small fault can put a lot of stored food at risk.
Every Sub-Zero model has its own parts list, so we start with the model and serial number on the rating label. That tells us the correct parts and any known issues or service bulletins for your unit.
Common Freezer Problems We Fix
Water leaking
A blocked defrost drain or a cracked drain pan.
Clicking but not starting
Usually the start relay or overload; sometimes the compressor itself.
Not freezing or food softening
A dirty condenser, a failed fan, a bad start relay or thermostat, or a defrost failure. Low refrigerant from a leak is checked if those are fine.
Heavy frost or ice build-up
A worn door gasket, a door that does not close fully, or a failed defrost heater or timer on frost-free models.
Runs all the time
Dirty coils, a bad gasket, a failing condenser fan or a freezer sitting in a space that is too hot or too cold for it.
Quick Checks Before You Call
These are safe for most owners and sometimes solve the problem without a visit:
- Check the thermostat setting and that the unit has power at the outlet.
- Make sure the door or lid closes tightly and the gasket is not torn.
- Clear frost thicker than a quarter inch on manual-defrost models.
- Check whether the freezer is in a garage that is colder or hotter than its rated range.

Do you work on all Sub-Zero models?

Should I repair or replace my freezer?
A freezer typically lasts about 10 to 20 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
