- Record the exact display wording and whether an audible alarm is present.
- Turn the refrigerator off if cooling is interrupted or the fault repeats.
- Move perishables if temperature is unsafe.
Service-only work
- Flame-sense, LP gas train, and refrigerator control diagnosis should be handled by a qualified Thetford/Norcold service professional.
