Norcold refrigerator: power module flash 2
Norcold documentation describes “power module flash 2” separately for each model line: Norcold N15DCX / N20DCX (“Fan over-current cut-out; load above 1.0 amp sensed on terminal F-”); Norcold N8DCX / N10DCX (“Fan Over Current Cut-Out; the load is more than 1.0 amp sensed on terminal F-”). Compare the wording for your model below.
Check your model first. The same code can mean different things on different models. Find the model number on the appliance's data label, then use the matching row below.

What you can safely check
- Record the displayed code or diagnostic flash count.
- Turn the refrigerator off if cooling is interrupted or the fault repeats.
- Keep food safety in mind and move perishables if needed.
- Record the exact display or LED state.
- Move perishables if temperature is unsafe.
Stop and call a technician for
- Fan circuit and compressor power-module diagnosis should be handled by qualified Norcold service.
Do not bypass compressor controls, fan circuits, thermistors, fuse protection, or DC wiring. Shut off the refrigerator and arrange qualified Norcold service for unresolved diagnostic faults.
