N/A | Poor cooling performance, increased power consumption, or unexpected rise in energy use Possible Cause: Refrigerator installed too close to a wall or with air inlet/outlet vents blocked (by vehicle parts, luggage, etc.), tilt exceeding 3 degrees, or clearance to the rear wall exceeding 25mm | Ensure adequate clearance and unobstructed ventilation around the refrigerator, verify the appliance is level, and check the gap to the rear wall. | DIY Safe |
N/A | Heat accumulation in the vehicle or behind the refrigerator Possible Cause: Inadequate heat dissipation from the condenser, lack of proper baffling, or clearance to the rear wall exceeding 25mm without adequate ventilation | Improve ventilation behind the unit and ensure correct clearance/baffling per the installation instructions. | DIY Safe |
N/A | Unburned/unburnt gas smell or exhaust gases entering the vehicle interior Possible Cause: Air inlet vent located too high (preventing complete evacuation of unburnt gas) or inadequate sealing between the refrigerator and the vehicle body | Check the position and sealing of the air inlet/outlet vents against the installation instructions. | DIY Safe |
N/A | Compressor does not run at low ambient temperatures (approx. below 0C) Possible Cause: External ventilation grilles left fully open (or not fully closed) when replacing an absorption unit with a compressor unit, or compressor compartment too cold | Adjust the external ventilation grilles per the compressor retrofit instructions. | DIY Safe |
N/A | Refrigerator does not cool sufficiently Possible Cause: Inadequate ventilation around the cooling unit, evaporator iced up, or temperature setting too high | Improve ventilation, defrost the evaporator if iced, and check the temperature setting. | DIY Safe |
N/A | [12V DC] Error code W02 / continuous LED: Defective temperature sensor in cooling compartment Possible Cause: Faulty or disconnected internal temperature sensor | Check the sensor wiring and connection; replace the sensor if faulty. | DIY Check / Tech Fallback |
N/A | [12V DC] Error code E03 / 3 light impulses: Communication error Possible Cause: Bus or display communication failure between internal modules | Check internal wiring/connectors between the display and control modules. | DIY Safe |
N/A | [12V DC] Error code W10 / continuous beep: Door open longer than 2 minutes Possible Cause: Refrigerator door left open | Close the refrigerator door. | DIY Safe |
N/A | [12V DC] Error code E32 / 2 light impulses: External fan overcurrent Possible Cause: Cooling fan drawing excessive current or jammed | Check the cooling fan for obstructions or mechanical failure; replace if faulty. | DIY Safe |
N/A | [12V DC] Error code E33 / 3 light impulses: Compressor fails to start Possible Cause: Compressor unit locked or electrical drive failure | Contact an authorised service agent. | Professional Intervention Required |
N/A | [12V DC] Error code E34 / 4 light impulses: Compressor overloaded Possible Cause: System blockage or excessive operating load | Check for blockages in the cooling system; contact an authorised service agent if the fault persists. | DIY Check / Tech Fallback |
N/A | [12V DC] Error code E35 / 5 light impulses: Compressor controller thermal fuse tripped Possible Cause: Overheating of the compressor electronics due to poor ventilation | Improve ventilation around the compressor electronics. | DIY Safe |
N/A | Ammonia smell, or cooling circuit damage/leak detected Possible Cause: Refrigerant/cooling circuit compromised, damaged, or ruptured | Stop using the appliance and contact an authorised service agent immediately - do not attempt to repair the cooling circuit yourself. | Professional Intervention Required |
N/A | Total/complete battery discharge when vehicle engine is off Possible Cause: DC heating element (12V) connected directly to the battery without an ignition-controlled relay | Ensure the DC heating element's supply line is wired through an ignition-controlled relay, not directly to the battery. | DIY Safe |
N/A | Device does not start, or system shuts down unexpectedly Possible Cause: Vehicle's battery management system shut down the device to protect the vehicle battery from over-discharge | Check the vehicle battery charge state and battery management system settings. | DIY Safe |

Frequently Asked Questions
Q: What does climate class of SN (Sub Normal) mean?
The climate class SN (Sub Normal) defines the intended ambient temperature range for the absorption fridge's optimal operation.
Q: What’s the cooling performance in warmer ambient temperatures?
Cooling performance for absorption fridges is affected by warmer ambient temperatures. Ensure proper ventilation around the unit as detailed in the manual to maintain performance.
Q: How to operate an RMxxxx with a solar panel?
To operate an RMxxxx series absorption fridge with a solar panel, ensure the solar system provides adequate 12V DC power or sufficient battery storage to handle the power requirements, particularly when running on DC mode.
Q: My RMxxxx needs to be replaced. What would be an alternative?
When replacing an RMxxxx series refrigerator, look for current Dometic absorption or compressor models matching the physical dimensions and energy source requirements of your motorhome cutout.
Q: The refrigerator does not work In AC power mode?
Check if the vehicle is properly connected to the AC mains supply, verify that the AC fuse in the motorhome is intact, and ensure the refrigerator is switched on to AC mode on the control panel.
Q: The refrigerator does not work In DC power mode?
DC mode (12V) typically only works while the vehicle engine is running and the alternator is supplying power, preventing the vehicle starter battery from draining. Check the 12V DC fuses, vehicle ignition connection, and input voltage at the refrigerator terminals.
Q: The refrigerator does not work In GAS mode?
Ensure the gas cylinder valve is open, the main gas shut-off valves in the motorhome are open, and there is no air trapped in the gas line (try igniting another gas appliance first). Check if the igniter is sparking and that the burner is clean.
Q: In automatic mode: The refrigerator is being operated with gas although it is connected to The AC power supply?
In automatic energy selection mode, if the AC voltage is outside the acceptable tolerance range or unstable, the control system automatically switches to gas mode as a safety fallback. Check the AC supply voltage and connections.
Q: The refrigerator is not cooling adequately?
Verify that ventilation grilles are not blocked, check that the thermostat is set correctly, ensure the door seals tightly, do not overpack the interior restricting airflow, and verify that the selected energy source (AC, DC, or Gas) is actively functioning.
Q: WARNING type fault messages
WARNING type fault messages indicate a non-critical operational issue or prompt. Consult the user manual for the specific warning code displayed on the 10-series control panel to take corrective action.
Q: ERROR type fault messages
ERROR type fault messages indicate a critical system failure that stops the refrigerator from functioning safely on the current energy source. Check the specific error code on the display, troubleshoot the underlying power, gas, or ventilation issue, or contact customer service.
