Applies to: RM8xxx, RMS8xxx, RML8xxx, RMSL8xxx, RM8501, RM8505, RMS8501, RMS8505, RML8555, RMSL8505

What AC power not connected or AC voltage < 190 V means

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.

Owner-safe checks

  • 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.

Service-only work

  • AC voltage diagnosis, shore-power wiring, fuses, heating elements, and refrigerator electronics diagnosis are service-only.

Safety boundary

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.
