Norcold Refrigerator Error Code no AC, no FL

This combination fault means the power board detected AC input voltage below 85 VAC and automatically switched the refrigerator to LP gas mode. After switching, the board attempted to ignite the LP burner but could not confirm a flame was established. Both failures are logged together because they occurred as a linked sequence. You need to resolve the low voltage issue and the ignition failure separately to restore normal operation.

The no FL fault portion of this error does carry a safety consideration, because a failed ignition sequence means unburned LP gas may have been briefly released near the burner. The control board is designed to shut off the gas valve quickly when no flame is detected, limiting exposure. However, if you suspect a gas leak or detect a propane odor, ventilate the area immediately and do not attempt to operate the refrigerator until the gas supply and burner system have been inspected and confirmed safe.

Repair costs vary widely depending on which components need attention. Resolving a low voltage issue may cost nothing if it is a simple campground or cord problem, or it may require converter or inverter service ranging from roughly 100 to 400 dollars. LP ignition repairs such as cleaning the burner or replacing an igniter or flame sensor typically range from 50 to 200 dollars in parts. If the power control board requires replacement, costs can range from 200 to 500 dollars or more depending on the specific board and labor involved.

Begin by checking the AC power source: measure the voltage at the outlet or power input and confirm it is above 85 VAC. Correct any wiring issues, replace extension cords, or contact the campground if the pedestal voltage is low. Then address the LP gas side by verifying tank level, confirming valves are open, and inspecting the burner, orifice, igniter, and flame sensor for blockages or damage. Both conditions must be corrected before the refrigerator will return to normal Auto mode operation.

A reset may temporarily clear the fault display, but the underlying conditions will cause the faults to return if they are not corrected. If AC voltage remains below 85 VAC or the LP burner still cannot establish a flame, the refrigerator will cycle through the same failure sequence and log the errors again. Resetting is useful for confirming whether a fault was intermittent, but it is not a substitute for diagnosing and repairing the root causes.
