What Display fault 05 means
The Dometic RM10 support page asks which operation mode is selected for display fault 05: gas, 12 V DC from a battery, or 230 V AC.
Owner-safe checks
- Record the selected operating mode and whether the RV is on gas, 12 V DC, or 230 V AC.
- Use only normal front-panel controls to select a different energy mode if one is available and safe.
- Call qualified service if the fault remains after normal power-source selection.
Service-only work
- AC supply, DC supply, heater, wiring, and refrigerator control diagnosis are service-only.
Safety boundary
Do not service LP hardware, electrical circuits, wiring, or refrigerator controls; use only normal front-panel and owner-visible checks and call qualified service for repeated faults.
