Norcold Refrigerator: “AC / rE flashing”
warning RV refrigerator error codes
What it means
The flame-sense circuit on the control has failed, so the refrigerator cannot reliably tell whether the gas burner is lit. Reported as a power board fault rather than a fuel problem.
Most likely causes
- Failed flame-sense circuit on the rear power board most likely
- Damaged sense wiring between the electrode and the board common
Safe checks you can do yourself
- Confirm the code by cycling the fridge OFF then ON
- Visually check the flame-sense electrode lead for damage or a loose connection (with the fridge off)
How to reset / clear AC / rE flashing
- Cycle the refrigerator OFF and ON to rule out a one-time glitch
- A repeating AC/rE fault is board-level and will not clear with a normal reset
When to call a technician
AC/rE persists after a power cycle; the service manual calls for replacing the power board.
Accuracy notes
Distinct from 'no FL' (a fuel/ignition trial failure); AC/rE indicates the sensing electronics themselves failed. Dealer-only per the manual.
