How to Troubleshoot a Dometic RM2401 Refrigerator

Dometic manufactures the model RM2401 refrigerator intended for use in recreational vehicles and camper trailers. This refrigerator can run on propane or electricity, allowing it to stay cool even when electricity is not available. It does not have a motor or moving parts, so troubleshooting a Dometic RM2401 refrigerator that is not functioning properly is fairly simple. Examine the refrigerator and determine the source of the problem.

Refrigerator Does Not Freeze or Cool

Step 1

Check the propane gas bottle for the Dometic RM2401 refrigerator. Refill, if needed.

Step 2

Unplug refrigerator and disconnect gas supply. Turn the screws on the burner-housing cover plate counterclockwise with a screwdriver to loosen them. Remove the cover. Disconnect the lighter cable connected to the electrode and loosen the burner fixing screw. Withdraw the burner and unscrew the jet. Clean the jet with alcohol or blow compressed air through the line to clear clogs. Replace the jet and burner. Reconnect the lighter cable and replace the cover. Plug back in and reconnect gas supply.

Step 3

Place a level in the bottom of the freezer compartment to determine whether the recreational vehicle or camper is level. Raise or lower the vehicle or camper until the bubble indicates that the Dometic RM2401 refrigerator is level. If the fridge operates while not level, the boiler box can sustain permanent damage.

Step 4

Remove items near the refrigerator that obstruct air flow. The refrigerator needs ample ventilation to cool properly.

Step 5

Move the Dometic RM2401 refrigerator thermostat close to the "Max" setting during hot weather.

Odors

Step 6

Unplug refrigerator and disconnect gas supply. Turn the screws on the burner-housing cover plate counterclockwise with a screwdriver to loosen them, if the position of the burner needs adjusting (if the flame touches the side of the boiler, it produces smoke and causes an odor). Remove the cover. Disconnect the lighter cable connected to the electrode and loosen the burner fixing screw. Withdraw the burner, then carefully reinstall it in its correct position. Reconnect the lighter cable and replace the cover. Plug back in and reconnect gas supply.

Step 7

Follow the directions in Step 1 if the burner is damaged, replacing the burner instead of reinstalling it.

Step 8

Loosen the screw securing the flue to the burner, if the flue becomes dirty and causes odor. Gently pull the flue top to remove it. Clean the flue with a flue brush. Replace the flue top and tighten the screw that secures it.
