Dometic NDR 1062 fridge quit, won't run on AC or propane

Ours gets pretty warm, almost too hot to hold your hand on down near the burner.

Can't remember the exact resistance value but I believe the heating element in our Norcold is around 300 watts. At 120 volts that's around 2.5 ohms. You'll need to look up the value for your model Dometic.

It won't make much difference if you unplug it for a minute to measure the element resistance.

It's sounding more and more like you may have a blocked or empty cooling unit.
