Dometic Refrigerators - Recent Questions, Troubleshooting & Support


Since I don't know what does work I am kind of shooting in the dark.
Does the ac heater get hot ?
The spark ignitor is part of the control board. But won't work?
I assume that you have a user manual but I am including a link to download one.

Note that there are three fuses. B (12V control) and C (120V Heater) on the control board and a thermofuse L located on the stack.
If L is good and everything else is good there should be 12VDC on J1 and at Fuse B

Look at the back of your fridge by temoving lower vent / avross panel on outdide. Find the 12v power wires that are likely coming up from floor of compartmentn. They should go to a small terminal block. Make sure they are tight here, on both sides of the block.

Look closely in this area for a fuse holder, probably valued at 25 amps. Check this fuse, replace as necessary. If blown, can be caused by dc heater failing or converter may have surged while running on the shoreline.

Find the AC outlet where fridge is plugged into. See if it has a reset button on it, otherwise check bath and kitxhen outlets for an ourlet that resets the ground fault / earth leakage function. If this is tripped, may have been a surge when operaring on shoreline or generarator or a wiring problem could be present.

You may also have a bad mode switch, especially if frisge is gerting both 12vdc and ac power to it. Its not unusual for propane to continue to be able to operate since that is the preferred mode for most rv / caravan refrigerators.
