| Model line | What the manufacturer says | Source |
|---|---|---|
| Dometic RM10.5 / RMS10.5 (operating manual and RM10 fault support pages) | The Dometic RM10 support page lists this fault as AC power not connected or AC voltage below 190 V and asks which operating mode is selected. | Dometic RM10 Refrigerators Fault AC Power Not Connected Or AC Voltage Less 190 V Support |
| Dometic RM8xxx / RMS8xxx / RML8xxx / RMSL8xxx | The Dometic RM8 support page says AC power may not be connected or AC voltage is below the operating threshold; below about 195V the refrigerator stops working on 230V. | Dometic RM8 Refrigerators AC Power Not Connected or Low Voltage Support |
What you can safely check
- 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.
- Make sure there is a normal owner-visible connection to mains power.
- Record whether the fault clears after stable shore or mains power is available.
Stop and call a technician for
- AC supply, heater, wiring, and refrigerator control diagnosis are service-only.
- AC voltage diagnosis, shore-power wiring, fuses, heating elements, and refrigerator electronics diagnosis are service-only.
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.
Do not service AC circuits, wiring, fuses, heating elements, or refrigerator controls; use only owner-visible power checks and call qualified service for repeated faults.
Write this down before you call
- Interior data label model, product number, serial number
- Front display code or lamp state photo
- Power module/display board part number if service requests it
- Mains or shore-power status
