Norcold Refrigerator Error Code no FL

The no FL code means the power board could not detect a flame at the propane burner after an ignition attempt. It appears in Manual LP Gas Mode or alongside other faults in Auto Mode. The refrigerator shuts down gas flow as a safety precaution when flame presence cannot be confirmed. Common causes include LP supply problems, a dirty burner, incorrect electrode gap, a damaged igniter wire, or a faulty gas valve solenoid.

The no FL fault is a built-in safety response. When the power board cannot confirm a flame, it closes the gas valve to prevent unburned propane from accumulating in the burner area. This makes the fault itself safe, but you should not repeatedly attempt to restart the unit without diagnosing the root cause first. Repeated failed ignition attempts with a gas supply issue present can allow propane to collect before the board shuts down.

Repair cost depends on which component is at fault. If the fix involves cleaning the burner, adjusting the electrode gap, or purging the gas line, the cost can be minimal. Replacing a gas valve solenoid or LP regulator typically involves parts costs ranging from roughly 30 dollars to over 150 dollars, plus labor if a technician is needed. A damaged igniter wire or electrode assembly also falls in that mid-range cost category for parts.

Start by confirming all LP shutoff valves are fully open and the tank has adequate fuel. Check that LP pressure is at 11.5 inches W.C. and purge any air from the line after a recent tank change. Clean the burner, verify the electrode gap is between 1/8 and 3/16 inch, and inspect the spark-sense igniter wire for damage or loose connections. If those steps do not resolve the fault, test the gas valve solenoid resistance, which should read between 74 and 92 ohms.

A reset may clear the displayed fault temporarily, but the no FL code will return on the next ignition attempt if the underlying cause has not been corrected. The power board re-evaluates flame presence each time LP mode is activated. Diagnose and correct the root cause, such as a gas supply problem, blocked burner, or faulty solenoid, before relying on a reset to restore normal operation.
