How to fix Dometic RM3962 Refrigerator that does not work in gas operation mode?
If your Dometic Refrigerator isn't working in gas operation mode, start by checking if the LP gas bottle is empty and replace it if necessary.

If the problem persists, turn the refrigerator off and contact a Dometic dealer or Service Center for repair.
Why is my Dometic RM3962 not working and the interior light is off?
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.
How to adjust temperature of Dometic RM3962 Refrigerator if it is too cold?
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.
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.
