Why is my Dometic RM 8551 Refrigerator not cooling sufficiently?
- J
  Jon SmithAug 19, 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.

  There are several reasons why your Dometic Refrigerator might not be cooling sufficiently. It could be due to inadequate ventilation, so check that the ventilation grilles are not covered. The thermostat setting might be too low, so try setting it to a higher level. A heavily frosted condenser can also cause this issue, so ensure the refrigerator door closes properly. Avoid storing too much warm food at once, and allow food to cool before storing it. Also, the appliance needs time to cool down, so check after 4-5 hours of operation. High ambient temperatures can also affect cooling, so regularly remove ventilation grilles.

  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.
