How to Troubleshoot a Dometic RM2401 Refrigerator

If you're unfamiliar with the company Dometic, they manufacture appliances for the marine and RV industries. Dometic specifically creates the RM2401 refrigerator, which many people use in recreational vehicles (RV) or camper trailers. These type of refrigerators run off of propane gas and electricity. Due to this, they can sometimes need troubleshooting. Whether you're on a camping trip, or a family vacation they're relatively easy to operate.

How To Troubleshoot

Step One: Unplug The Refrigerator

Before you unplug the refrigerator, make sure to check the propane gas bottle to see if it needs refiling. Sometimes if your refrigerator is not working, the problem can be as simple as refueling your propane. No judgment, everyone's had their dumbfounding moments. After you check the propane, then you can unplug the refrigerator.

Step Two: Disconnect the Gas Supply

All you have to do is turn the screws on the burner-housing cover plate in a counterclockwise direction and remove the cover. It's easier to unscrew them with a screwdriver, but if you have a fancy drill that works as well. Next, you're going to disconnect the lighter cable by loosening the burner screw. Pull out the burner and unscrew the jet. If your jet is dirty, you can clean it with alcohol or go the old fashion way and blow into the compressor. This will help to clear the jet. Although this is the easier route, for a longterm fix you should properly clean the jet. Afterwards, you're going to put the jet and burner back in place, reconnect the lighter cable and replace the cover. You can now plug the fridge back in. Don't forget to reconnect the gas supply.

Step Three: Don't Obstruct Air Flow

This type of appliance needs the appropriate amount of ventilation to operate correctly. Make sure no items are blocking the refrigerator at any time. If you live in a particularly hot climate, move the refrigerator's thermostat closer to its max setting. This will ensure that the refrigerator doesn't overheat.

If Your Fuse Blows

Step One: Remove The Vent Cover

If your fuse blows, the first thing you may think is to call someone else to fix it. The phrase "blown fuse" sounds scary at best, but it's very easy to fix. The first thing you have to do when replacing your blown fuse is remove the vent cover. The vent cover is located outside of your RV because it gives you easier access to the back of your refrigerator.

Step Two: Locate The Black Box

On the outside of the RV, you'll see a black box. You're going to remove the cover and check the two fuses. One of the fuses is for the refrigerator control system, and the other one is for the AC cartridge heater. To replace the fuse, you need to disconnect the 12-volt wires. Remove the cover, take the blown fuse out and then you'll be able to replace with the same amp fuse.

Step Three: Keep An Eye On The Fuse

It's important to make sure that after you replace the fuse, you check it every hour for at least five hours. If the fuse is still not working, then you're going to have to call a technician. The good thing is that for the most part fuses only have to be replaced every couple of years.
