Why is my Dometic Refrigerator not cooling sufficiently?
- C
  Cheryl McphersonAug 17, 2025
  There are several reasons why your Dometic Refrigerator might not be cooling well enough: * The ventilation to the unit might be inadequate. Ensure that the ventilation grilles are not covered. * The thermostat setting could be too low. Try setting the thermostat to a higher level. * The condenser may be heavily frosted. Check that the refrigerator door closes properly. * Too much warm food might have been stored inside recently. Allow warm food to cool down before storage. * The appliance may not have been running long enough. Check whether the cooling compartment works after approximately 4 - 5 hours. * Ambient temperatures could be too high. Regularly remove ventilation grilles.

  If your Dometic Refrigerator isn't cooling while in gas operation mode, make sure the gas cylinder isn't empty and replace it if it is. Check that the upstream shut-off device is open. If there's air in the gas pipe, switch off the appliance and start it again; repeat this procedure 3-4 times if necessary.

  If your Dometic Refrigerator isn't cooling when running on 230V, consider the following: * The on-board fuse may be defective. Try fitting a new fuse. * The vehicle may not be connected to mains supply voltage. Connect to a mains power supply. * If it is AES, gas operation might be engaged despite connection to the mains supply voltage. In this case (automatically switches back to 230V operation) contact Dometic Customer Services. * The heating element might be defective. In this case contact Dometic Customer Services.

  Julie ThomasSep 8, 2025
  If your Dometic Refrigerator isn't cooling when running on 240V, check the on-board fuse and replace it if it's defective. Ensure the vehicle is properly connected to a mains power supply. If you have an AES (Automatic Energy Selector) model, it might switch to gas operation if the mains supply voltage is insufficient; it will automatically switch back to 230V when the voltage is adequate. If these steps don't resolve the issue, please inform the Dometic Customer Service, as the heating element might be defective.
