Dometic Refrigerator Error Code Orange (continuous)

A continuous orange light on Dometic RM3601, RM3801, and RM2802 models indicates that the refrigerator attempted to ignite on LP gas and failed. The control system ran through its ignition sequence, could not confirm a flame, and then locked out the gas mode. The unit will not attempt to run on propane again until the fault is cleared by resetting the main switch.

Start by confirming the propane tank has fuel and that all gas valves in the supply line are fully open. Next, cycle the main switch off and on to reset the lockout and observe whether the unit ignites. If it faults again, inspect the burner assembly for debris or blockage and check the igniter electrode for carbon fouling or damage. If the burner and electrode are in good condition, the gas valve or control board may need further testing by a qualified technician.

Repair costs vary widely depending on the root cause. Cleaning a blocked burner jet or adjusting an electrode position is largely a labor cost and could range from around $50 to $150 if done by a technician. Replacing a faulty igniter electrode or gas valve typically runs between $100 and $350 in parts and labor combined. If the control board is the source of the fault, expect costs in the $200 to $500 range or higher depending on parts availability and service rates in your area.

Yes, turning the main switch OFF, waiting 5 seconds, and turning it back ON will reset the ignition lockout and allow the unit to attempt another ignition cycle. If the underlying problem, such as low gas, a closed valve, or a dirty burner, has not been resolved, the orange light will return after another failed ignition attempt. A reset is a useful diagnostic step to confirm whether the fault is persistent or was a one-time event.

The orange indicator itself is a safety feature: it means the control system detected a failed ignition and shut down the gas mode rather than continuing to release unburned propane. If you smell gas near the refrigerator or anywhere in the vehicle, turn off the LP supply immediately and ventilate the area before performing any diagnostics. In the absence of a gas smell, the situation is not immediately dangerous, but the refrigerator will not cool on propane until the fault is resolved.
