dometic fridge intermittent

It sounds like a bad heating element. The check light is only for LP operation, indicating ignition failure.

UPDATE
I think it is pointing in the direction of a bad element....in short, the fridge works on gas but not on electric. fridge has 120VAC and also 12VDC to control board, but that is far as I checked.....

timeline....


Last night I plugged in the trailer to shore power and turned on the fridge. i put a indoor outdoor thermometer inside and outside the fridge which records the MIN/MAX temps. it ran on electric all night. Checked the fridge this morning and the inside fridge temp and outside fridge temp were the same, and by looking at the MIN/MAX temps recorded on the thermometer, the fridge neverworked at all throughout the night.

this morning around 9am I simply unplugged the fridge at the back and let it switch over to gas, it did and ran all day. checked it about 5pm and the inside temp of the fridge was 1 degree C, outside temp 15 degree .C worked great all day, water in ice cube trays froze solid.

So before i came home I plugged the fridge back in, I will check tommorrow to see after switching back to electric if it worked or not.

I'm suspecting the heating element might be bad, so when I go back to the trailer tomorrow I will try to test it.

I will consult the manual, but how does one test the element? if its a Resistance test.... typically what is the wattage of these elements, so I can compare the calculated resistance with the measured resistance.

thanks
