What Display fault 50 means
The Dometic RM10 support page lists display fault 50 and says to replace an empty gas cylinder, press the control knob for 2 seconds to reset, and note that altitude above 1800 can contribute.
Owner-safe checks
- Confirm from owner-visible indicators whether the LP cylinder is empty, and replace an empty cylinder using normal RV procedures.
- Press the control knob for 2 seconds once to reset the error after correcting the supply state.
- Record whether the fault occurs at high altitude or returns after the reset.
Service-only work
- Repeated ignition lockout, LP hardware, regulator, flue, and refrigerator ignition 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.
