What to do if Dometic RM3962 is not cold enough?

  If your Dometic Refrigerator isn't cooling sufficiently, several factors could be at play. First, verify that the thermostat is correctly set and adjust it if needed. Also, check if there's a power failure. Ensure the refrigerator is level, as absorption refrigerators need to be level to function correctly. Inspect the door gasket to confirm the door is closing properly. Remove any heavy frost buildup on the evaporator fins by avoiding leaving the door open unnecessarily. Finally, avoid overpacking the refrigerator; arrange food to allow for free air circulation.

Why is my Dometic RM3962 light on but not cooling?
- M
  Mary BrownAug 25, 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 RM3962 Refrigerator works on electric but not gas?
- T
  Thomas MataAug 26, 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.

  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.

How to fix flashing 'LP' message on Dometic RM3962?
- M
  michelle98Aug 28, 2025
  If the message 'LP' is flashing on your Dometic Refrigerator, it indicates that LP gas ignition failed. Try turning the refrigerator OFF and then back ON to return to normal operation. This issue might also occur if there's air in the gas line, especially after changing a gas bottle or after a long shutoff period. Repeat the lighting procedure (45 seconds) by turning the refrigerator off and on several times to purge the air. Ensure that the LP gas bottle isn't empty and needs replacing. If the problem persists, it could be due to an obstruction in or on the burner or burner jet, or the burner jet is clogged and should be cleaned; in this case, turn the refrigerator off and contact a Dometic dealer or Service Center for repair.

What does E3 error mean on a Dometic RM3962?
- C
  Cole CookSep 9, 2025
  If 'E3' is displayed and two thermostat range setting lights are flashing on your New Generation Dometic Refrigerator (First generation DMR702 and DMR702-D models only), the thermal fuse might be tripped, or the thermofuse could be defective. Improper installation might have caused an imbalance in the airflow around the refrigerator.

How to adjust temperature of Dometic RM3962 Refrigerator if it is too cold?

  shawwilliamSep 5, 2025
  If your Dometic Refrigerator is too cold, check if the thermistor bracket is dislocated. If so, clip the thermistor bracket to the last fin on the right side of the cooling flange and center it vertically on the fin. Also, check if the thermistor bulb is dislocated; position it inside the thermistor bracket groove and center it vertically in the bracket.
