Sub-Zero Refrigerator Not Freezing in Tarpon Springs: A Failed Evaporator Fan
- Symptom
- Freezer not holding temperature and not freezing.
- Cause
- Failed evaporator fan motor.
- Fix
- Replaced the fan motor the same visit.
A built-in Sub-Zero refrigerator in Tarpon Springs wasn’t cooling properly — the freezer section wasn’t holding temperature and had stopped freezing.
Tracking down the cause
The evaporator fan — the motor that circulates cold air from the evaporator coil through the freezer — had failed. Without it running, the coil couldn’t move cold air where it needed to go, so the freezer just couldn’t keep up.
Not the easiest compartment to work in
This particular Sub-Zero design packs the evaporator, fan, and icemaker components into a tight compartment that’s genuinely awkward to take apart and put back together — one of the more frustrating layouts we run into. Having the replacement fan motor on hand meant we could still get it done in the same visit.
Result
With the new fan installed, the freezer is back to holding temperature normally. If your built-in refrigerator’s freezer section isn’t freezing the way it should, a failed evaporator fan is one of the things worth checking — even on the more complicated designs.

FAQ
Why is my Sub-Zero freezer not freezing?
A failed evaporator fan is one common cause — without it, cold air doesn't circulate through the freezer.
Is the Sub-Zero evaporator fan hard to replace?
On this design the compartment is tight and awkward, but with the part on hand it can be done in one visit.
