Why is my Dometic DM2672 Refrigerator not working and the interior light is off?
- M
  Mark WatsonAug 21, 2025
  Your Dometic Refrigerator might not be working, and the interior light might be off due to several reasons. It could be that the mode or a switch is set incorrectly. Also, the DC voltage might be too low or absent. Another potential cause is a blown thermal fuse or thermo fuse. Faulty, shorted, or miswired wiring can also be the reason. Finally, the upper control module might be defective, or there could be a short or failed circuit in the lower control module.

Why is my Dometic Refrigerator light on but not cooling?
- J
  Jasmine OlsonAug 23, 2025
  If your Dometic Refrigerator isn't operating but the interior light is on, the issue might stem from a few potential causes. Check if the mode or a switch is set incorrectly. It's also possible that the DC voltage is too low or absent. The thermistor might not be operating within the proper temperature range. Another potential cause is that the communication wire harness has lost continuity or is shorted to ground. Lastly, there might be a short or a failed circuit in the lower control module.

Why Dometic Refrigerator works on electric but not gas?
- M
  Megan BradfordAug 25, 2025
  If your Dometic Refrigerator operates in electric mode but not in gas mode, several issues could be the cause. First, check if the mode or a switch is set incorrectly. The gas pressure might be too low or absent. Ensure the knob on the gas valve hasn't been turned to the off or closed position. Altitude might be affecting the refrigerator's operation in gas mode. The re-igniter might not be creating a spark, or the resistance on the gas valve solenoid might be out of specification. The orifice could be blocked or incorrectly sized. For older Americana models, the thermocouple might be defective. The burner could be blocked, the wiring might be faulty, shorted, or miswired, or there could be a short or a failed circuit in the lower control module.

Why is my Dometic Refrigerator freezing food?
- K
  Krystal ContrerasAug 27, 2025
  If the fresh food compartment in your Dometic Refrigerator is freezing, it could be because the thermistor is not operating within the proper temperature range, or there is a short or a failed circuit in the lower control module.

Why is my Dometic Refrigerator not cooling well on gas?
- J
  jliAug 27, 2025
  If your Dometic Refrigerator operates in gas mode but does not cool properly, the flue baffle is likely out of place or damaged.

Why is my Dometic Refrigerator not cold enough?
- C
  Corey BeltranAug 29, 2025
  If your Dometic Refrigerator or freezer isn't getting cold enough, several factors could be at play. Improper installation might have caused an imbalance in the airflow around the refrigerator. The fan switch could be defective. Ensure the refrigerator level is within tolerance. A warped door could also be the cause. For RM1350 models, the relay might be defective, or the flapper guide might need adjustment. Additionally, the thermistor might not be operating within the proper temperature range, or there could be a short or failed circuit in the lower control module.
