      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.

    • F
      fadamsSep 1, 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.
