What to do if my Dometic COOLMATIC has poor cooling and the interior temperature is increasing?
- M
  Monica BakerAug 20, 2025
  If your Dometic Refrigerator isn't cooling well and the inside is getting warmer, it could be due to several reasons. The compressor might be running for too long or constantly. Make sure there's enough ventilation around the refrigerator by moving it to another location if needed. The condenser might be dirty, so try cleaning it. Also, check the fan; if it's faulty, consider replacing it.

What to do if my Dometic COOLMATIC voltage is present but the compressor doesn't run?
- B
  Benjamin JohnsonAug 22, 2025
  If voltage is present but the compressor in your Dometic Refrigerator isn't running, it could be due to high ambient temperature. Insufficient ventilation could also be the cause, so move the refrigerator to another location. Another possibility is a dirty condenser; clean the condenser.

  Jose SinghAug 26, 2025
  If your Dometic Refrigerator has no voltage, check for interruptions in the connection supply line and establish a connection. If installed, the main switch might be faulty, so replace it if necessary. Also, if there's an additional supply line fuse installed, see if it has blown and replace it if needed.

What to do if my Dometic COOLMATIC Refrigerator makes a loud humming noise?
- B
  bailey73Aug 27, 2025
  If your Dometic Refrigerator is making a loud humming noise, it could be because a component of the refrigerant circuit is touching the wall; carefully bend the component away from the obstruction. Alternatively, there might be a foreign object stuck between the cooling unit and the wall; remove the foreign object.
