NDR 1062 Dometic Refrigerator

Since it does not work on either AC or gas - do you have DC to the unit? I have spent many hours troubleshooting a Dometic that turned out to be a corroded DC connection.

There is a control board and a step down transformer that may be at fault.
These should be located in the lower rear of the unit.

I assume you've checked baffle distance above flame? Anything changed above fridge, as in clearance, ventilation above etc. Maybe even removed a piece of panel, that was used above fridge for vent deflection etc?

turn of you power to refrigerator this will allow this will allow gas circuit to take over

Propane refrigerators have a gas burner to create the heat for refrigerant circulation. Some propane refrigerators that were used mostly in RV's also had an electric heat element that ran off a power cord or 12 volt battery.

To determine this look at the back of the refrigerator, you will see a gas line that ends in a burner on the lower left side (looking from the back). Just above that about 4 inches will be wires coming out of the box if an electric heat element is used.

Replaced the propane refrigerator with a 120v/12v compressor, Norcold DE0061T. Will never use propane cooling again - too many hassels.

NDR 1062, cools with gas but will not switch over to Ac . If i turn off lp, check light comes on and doesn't cool
