Norcold Refrigerator Error Code FL --

FL -- means the power board detected a flame signal when there should be no flame present. This indicates the gas valve is mechanically stuck in the open position, allowing gas to flow and sustain combustion even when the control system has commanded it to stop. The code can appear in any operating mode. The gas valve must be replaced to correct this condition.

Yes, FL -- is a safety-related fault. A gas valve stuck open means LP gas can flow and a flame can burn even when the refrigerator control system has commanded the burner to shut off. Until the gas valve is replaced, the refrigerator should not be operated on LP gas. Shut off the LP supply to the unit until the repair is completed.

Repair costs depend on the specific Norcold model and whether the work is done professionally or as a DIY repair. The gas valve part itself typically falls in the range of $50 to $150 or more depending on the model. Adding professional labor for an RV technician or appliance repair service could bring the total to $150 to $400 or higher depending on your location and shop rates.

Resolving FL -- requires replacing the gas valve, which involves disconnecting LP gas lines and working with the burner assembly. This type of repair is best performed by a qualified appliance or RV technician with experience handling LP gas components. A knowledgeable DIYer comfortable with gas appliance work may be able to complete the repair, but proper leak testing after reassembly is essential.

No, resetting the unit will not clear the FL -- error or fix the underlying problem. The fault is caused by a mechanical failure inside the gas valve, which cannot be corrected by cycling power or performing a control board reset. The error will return as long as the faulty valve remains in place.
