Dometic absorption fridge fault codes
The E-codes below are for the RM1350 series (4-door Elite style, including RM1350SL). Other Dometic models use different codes or indicator lights. Match the model label first.
Dometic fridge code E0
Display not talking to the power module. Check the display cable and plug, and 12V at the module. Reseat connectors. Replace the display or module if it persists.
Dometic fridge code E1
LP operation hardware fault. The LP system has a fault. See if AC mode still works. Service the LP gas valve, ignition or control. Do not skip safety checks.
Dometic fridge code E2
Temperature sensor or its circuit. Check the sensor plug and wiring. Measure the sensor ohms. Replace if open or shorted.
Dometic fridge code E3
Cooling unit malfunction. This is not the LP ignition code. Check heat on both LP and AC, ventilation and level. Run the full-run test. May need a cooling unit.
Dometic fridge code E4
DC voltage out of range. Check the battery, charger or converter, and voltage drop on the 12V supply to the fridge.
Dometic fridge: Flashing LP
LP ignition did not finish. After a tank change or long storage, turn the fridge off and on at the front. Bleed air from the line. If it returns, check gas pressure, burner, electrode and sensor.
