Fridge works on gas...but not on AC

there should be a small black box transformer wired into the ac cord
that goes to your standard plug
the transformer should then have wires going to your heating element
If someone has removed the transformer just order a 110vac to 12v 12 amp transformer and wire it in like you would a doorbell
when the transformer is working you should feel heat at the rear of your refrigerator at the heating element

Unplug the fridge. Remove the cover from the circuit board, unplug the 2 wires going to the heat element and do an Ohms reading should be 35-45 Ohms. If the Ohms is good then you need a circuit board as long as you have checked the 110 volt fuse on the circuit board.

I have the same unit and the same model number. Mine also not heat up. upon investigation I noticed the heating element has a 4 wires which I believe each pair (2 wires) meant for 100/120V and the other one is for 220/240V. I checked 2 wires (1 pair) has an open circuit while the other pair is ok. I directly connected the heating element to the power and it was heated up. I measured the resistance and it was around 78 ohm. from my lame calculation this is for 100/120V heating element. the 220/240V was busted.

Since mine on 220/240V power grid, to use the working 78 ohm heating element the estimated power would be P=VxV/R, around 738W which is way too high than the rated power (365W) for this voltage. I plan to add the dummy resistor 82 ohm + 78 ohm heating element to reduce its power around 370W. Hope it works.

To get proper heat, keep your temp setting at +5 degree than your temp and also mode in "heat "position. If still noheat, check your heating sensor for closed circuit by an OHMs metre.It it'swith RV, check power to RV.Ifit's with heating element check power to element. If power is there but stillno heat means element defective. Replace new heating element. Thanks.

To get proper heat, keep your temp setting at 30+ degreeand also mode in "heat "position. If still no heat, check your heating sensorfor closed circuit by an OHMs metre.It it's with RV, check power to RV.Ifit's with heating element check power to element. If power is there but stillno heat means element defective. Replace new heating element. Thanks.

Hi!!

Right beside the circuit panel, there is a grill, remove the 4 screws to gain access to the transformer/battery charger. You'll see a double power outlet, one cord is from fridge, the other is from the transformer. UNPLUG Transformer cord and reset breaker.

It will take a couple of minutes for the fridge to change to AC if you have it in AUTO. If everything works fine, REPAIR OR REPLACE TRANSFORMER/BATTERY CHARGER.

Don't forget to rate this answer, Good Luck!!!

are you running gas to oper the frig in the rv or electricty if only using the heating element for the frig RV STYLE ONLY maybe starting to make and break causing intermittent cooling or not enough cooling in frig but at all thing concerned try to increase you temp setting higher if you have that option

On the back of the unit, at the bottom, there should be a panel that is removable. Inside should be a fan, the condenser coil, and the compressor. The fan has to be constantly blowing air over the condenser coil, to dissipate the heat (which it is essentially being removed from the refrigerator by the compressor)

When the entire fridge stops cooling, one of three things have happened. The fan isn't removing the heat from the coil, or the compressor isn't compressing the freon, or the freon has somehow leaked out of the system. If it is the fan, you have an easy do it yourself repair. If it is the compressor or the freon, you will probably (but not necessarily) need a professional.

Inside the fridge, there is a coil that is cold instead of hot. A fan must continually blow over that one too, to circulate the air over the cold coils. The fan usually only works when the doors are closed, so be sure to have the door switch pressed to "shut" when checking it.

Check those and post back. And, I know... it really is Dometic.
