If your refrigerator has had a recall done on it I would check the L shaped bracket that was added as part of the recall, as it may have pinched thermal flame sensor and driving may slightly reposition it to cause an intermittent short blowing your 15 a fuse in rv panel. Remove it from the retaining fingers and slightly reposition fingers loosely around black insulation sleeve and reattach it to the previous location with the 2 sheet metal screws.
Now if the refrigerator won't come on at all check the resetable hi limit switch that is riveted to your units boiler area a few inches above your gas flame area. It has a button you can press located in between the 2 connectors.
Check for 12 VDC at the nylon terminal block in front of your main board AND on terminal J4. If power is there follow to the resetable hi limit switch on boiler. If you don't have power at all you may very well have a control board failure. You should check all 3 fuses on the control board also. So check all 4 Fuses (ONE) 15A on the RV Panel and the (THREE) fuses on the main board. If any of them are blown you can replace them ONCE only. If it blows the 15A Fuse on the RV panel again your going to have to locate the short most often from the RV panel to the main board on the refrigerator. If the fuses on the mainboard blow your going to have to troubleshoot the refrigerator wiring.

    Here is the Service tips: http://www.gasrefrigeration.net/dom_tech...



    There are only 3 fuses. 15A on the RV panel, 3A & 5A on the lower control board. See pages 11 and 12 of the service tips for fuse location and board differences. Note that the lower control board part numbers are slightly different as is the fuse location depending on what version is installed. Replace any blown fuses. If a fuse fails again enlarge the schematic on page 16 of the service manual and follow each of the components from board to the component checking for shorts of wires and the the components. The service tips has all of the checks listed.

2003 wildwood Le trailer how do we light the gas on the refridgerator??? Did not come with manual.


Your fridge should have a switch for propane/electric/automatic. This is usually located above the fridge door & just below the freezer door. When on propane the gas will feed directly to the fridge there us no need to light it! However the propane needs to feed from the large propane tank usually mounted on the tongue of the trailer to the fridge....this takes some time . We usually light our drove first then wait a few minutes & then turn on the fridge. Please know that it takes a few hours 10-12 fir the fridge to cool down to acceptable temps.
Now if u do all the above u may have a blockage (mud dauber) in the propane line - which u can usually access thru the fridge access panel on the outside of your trailer. Bees seem to be drawn to the Oder if propane. Make sure prolate tank is shut off! Take a small brush & clean the inside of the propane line & then start from the beginning.

When the switch is set to electric, you should notice the fridge getting colder in a few hours. Again 10-12 hrs before it us acceptable to place food in it.

When the switch is in the auto mode it will automatically switch from electric to propane when you lose electricity for any reason & back to electric is you run out of propane - or shut it off.

Oh one last thing you must have your battery on in order for the fridge to work!

Good luck!

Have a dmetic rm 2652, have power in fridge but no freezer or cold in fridge,tried restarted 3-4 tims still no good,trieda new 5 amp fuses ran 3 minutes stopped again?


On most Dometics, When you have a cooling problem follow these steps and it will resolve your problem or at least tell you what is wrong.
Check main terminal Block for proper Voltage
Check Heating element for proper ohms, 2652 is 44ohms
Disconnect P-2 wire on board for approximately 12 to 18 hrs. This makes the unit run constantly in case there is a clog in the unit.
The only other thing you may do is check the thermistor operation, Unplug the P-2, remove the thermistor from inside the refrigerator, put it in ice, You want the thermistor to drop to about 32 degrees, Check the ohms, they should be at 8,000 to 10,000 ohms.
If all checks out, you have either a bad board, not common, or a bad cooling unit, common

Dometic refrigerator RM 2652 is not working


The fridge needs a 12 volt DC source to operate properly, which should be connected at the back of the fridge, outside behind cover. Check all fuses in your fuse panel as well. The upper controls are powered by 12 volt DC system, and that's what tells the fridge what to do.. (battery or converter)

Rm 2652 stays on a while then cuts off and stays off


If you have the yellow epoxy filled circuit board from around 1993-1996 rather than the green newer one you can see the circuits on (take the black cover at back of fridge off to check) it is most likely just a bad circuit board. Otherwise it is most likely low voltage or a bad ground on the 12volt power coming into the fridge. Also make sure your thermostat(if available) is on maximum during testing.
