Dometic Refrigerator Error Code Flashing Red (10 sec)

This code means the refrigerator attempted to ignite the LP gas burner but failed to achieve a spark within approximately 10 seconds. It is a 3rd generation control board fault that locks out gas operation until the ignition problem is resolved. The most common cause is a grounded electrode assembly or a shorted high-voltage ignition wire. The unit will not cool on gas until the fault is diagnosed and corrected.

A reset may temporarily clear the fault and allow the unit to attempt ignition again, but if the underlying problem with the electrode or wiring is not corrected, the fault will return within the next ignition cycle. Resetting without repairing the root cause is not a lasting solution and the unit will continue to fail on gas mode.

Repair costs depend on which component has failed. An electrode assembly replacement typically runs in the range of $20 to $60 for parts, while a high-voltage ignition wire or igniter module can range from $30 to $100 or more depending on the specific model. If a technician is needed to diagnose and perform the repair, labor costs will add to the total.

Start by inspecting the electrode assembly for cracks, carbon tracking, or contact with any grounded metal surface. Check the high-voltage wire along its entire length for damaged insulation or pinching. Verify the electrode gap is exactly 3/16 inch using a feeler gauge. If the electrode or wire is damaged, replacement of the affected component is required.

The fault code indicates the ignition system failed to spark, which means the gas valve did not open and no gas was released into the burner area. The control board is functioning as intended by preventing gas flow without a confirmed ignition event. However, you should still inspect the electrode and wiring promptly, as a shorted high-voltage wire can degrade further and a cracked electrode can worsen over time.
