Dometic Fridge will not run on electric

[pcoole55]

We bought a used 2005 Rockwood Forest River TT. It is not our first rv and not the first time our fridge has on/auto/gas. BUT it is the first time I came across the problem of it NOT Cooling and freezing ON ELECTRIC. It had power because the light worked and the small circulation fan that previous owner installed runs.
A few days after we got the TT my ac thermostat was not working...its on 12v. Got a repairman out and it was the converter that had died, it was only pushing like 3v.

But we put the fridge on, clicked auto and within a few minutes the CHECK light comes on. We have replaced fuses, checked the connections outside, checked fuse panel inside.

Are we just missing something? Do you have any idea what we need to do ...can not pay repariman this time

I believe the check light only comes on when in gas mode and there's a problem.
I've been wrong before so if I am this time I'll add it to my "I was wrong" list.

Are your propane tanks on?

You said you checked the fuses, is that just the ones inside or also the ones outside under the black cover that's mounted directly to the control board?

I had to replace the electric element on my old camper a few years ago. That was a crappy job, but it solved the problem. I am not sure what made it burn out, but something did.

Before you go to that trouble, check the GFCI plugs in and outside of the camper. On our popup the fridge element plug ran through the GFCI. Once in a while it would get reset in transit and then the fridge did not work on AC.

1) The black on/off switch is a "climate control" and is run off the battery power. It should be turned off when boondocking (no AC shore power) to extend battery life.

2) The check light means that the fridge is not getting 120 volt AC power AND/OR the gas will not light "for some reason" (normally no gas pressure if it has worked on gas before). If the GAS button is "OUT", it will not work on AC shore power even if it is available. Make sure it is "IN" to allow the AC shore power to work.

Make sure you have AT LEAST 12 volts of battery voltage AND the gas is on and you can run the range burners (good pressure).

IF still no light with good gas pressure and voltage; press the stack over-temperature fuse to make sure it has not opened. (You may need to remove the metal cover plate to get to it, but if you have skinny hands you should be able to get behind it without cutting yourself on the metal.)

Do not worry about the internal glass fuses unless you do not have 12 volts (lights on panel do not come on when in AUTO) or it works fine on gas but does not work on shore power ONLY.

I have had similar problems with my Dometic Rm1350. My model has a 5A/110V glass fuse on the control board. This fuse protects the board and usually blows if there are power surges. It will also blow if the AC heater for the frig is bad. You might want to look for this type fuse and check its resistance. I get replacements at the Home Depot. If you have one and it continues to blow I would suspect the heater element is bad.

X2 on the blown fuse..replaced it and all seems to work fine.
