Check the 12V supply, and if recall kit is installed, check the limit and thermal fuse.

My dometic model #2652 has no electric,why??


Check the fuses on the lower back of the unit. There is a control board with them on it. If the fuses are good, you will need to replace the control board. Here is the manual for that unit.
Here is the control board in case you need to order it.

RM6270 in a touring caravan, over 5 yrs old. Worked fine until mid-Sept, when it ceased on 240V, 12V & gas still good. Any other sources of the problem possible, other than the 240V element (e.g. power...


Some of the Dometics have what was called the 'Dinosaur Board' which is a circuit card which controls the unit.

Not sure if it applies to your exact model, but if there is a company who just makes replacement control boards for Dometic fridges, that is a big fat clue, in my book. Cheers.

not likely but possible. if they already had one bad board what's to say their production methods have changed since they made your last bad board. I have just had 6 bad compressors from this chinese company danfoss in one month! for only 2 freezers i have installed 3 bad compressors in each! nobody takes pride in production anymore they want the stuff to break.

My dometic 2611 dosent want to operate correctly. Check light consistantly comes on. I'mm connected to ac power all of the time. AC sometimes works for a day or so then it might switch to gas for no...


If your unit is automatically switching from AC to gas for no reason, then you either have a problem with the power supply or the lower control board. On the outside of the fridge, there is a black box located in the lower left corner, this box is the control unit. The control unit senses the incoming power source and automatically switches it to LP if no AC power is available.

Turn the refrigerator on and set it to auto. Let it run until you notice that it switches to gas. Immediately go outside and check for incoming 120VAC power at that lower board. If you have power there, then you have a bad board. If you do not have power, then you have a power supply problem. Check the electrical plug and outlet in the fridge compartment and also make sure that your GFCI's throughout the coach are ok.

Hope this helps,

Jeff

Light stays on check when on ac on Dometic Fridge


Here's some info regarding the check issue you're experiencing:

Problem. Unit controls go to "check"
There is a common problem with, Dometic RM2807 or RM2811 and most later model Dometics with upper controls. The refrigerator's "check light" comes on or the refrigerator just shuts down seemingly for no reason. Another common problem occurs while on 120v. The refrigerator might switch to gas or just shut down even while you have a good 120v supply.

Answer. Dometic RV refrigerators with the push button upper control boards have a problem with the main power boards. The power board components are encased in yellow epoxy, reducing heat transfer. This tends to cause them to run too hot which in turn can often cause the power board to fail completely or cause problems such as listed above. We have found the only effective repair is to replace the power board. We do not use the Dometic replacement as they too can fail. The Dometic replacement also requires you to rewire the board and gas valve. The only board we recommend is the P-711. The P-711 not only will fix these problems but does not require the rewiring. It uses all the standard wiring. See Power Boards

Hope you find this helpful and best regards!
