Engel 12v fridge overcools even when thermostat down. how do i access the thermostat

If the fridge is overcooling it could be the thermostat. If the defrost panel is permanently switched on, overcooling might not be noticed but the condenser will become quite hot.

If running continuously, there is no overcooling and the condenser remains cool, either the compressor is defective or the refrigerant has leaked away.

Enter "Engel Perth WA" and do a search.

The compressor is on the way out and exceeds the current capacity of the 12v inverter circuit. The compressor runs on 32V AC @50 Hz and the inverter circuit is not able to produce sufficient current when the compressor becomes worn. It still runs on 240V circuit as this is a straight step down transformer from 240 volts and is not current limited..

the owners manual will tell you but yes most do

check or replace thermostat(s)

Engel do not sell individual refrigeration components. Unfortunately. But you can buy from them a complete evaporator, compressor and condensor pre-assembled. You just need to make up a box. The electronic control box is also available as well as the thermostat. I am not sure who you can contact in the USA but I am sure if you go to www.engelaustralia.com you should be able to track down someone in the US who can supply those parts. Alternatively you can make up one using a Danfoss BD35 compressor with a dual control, which can run on 12vdc, 24vdc and 220vac. You then just need a wide range thermostat -30/+30c and you are away.

AUTOMATIC AC/DC CHANGEOVER: All Engel Fridge Freezers can be plugged into both AC and DC at the same time. The Engel is smart enough to use the AC while available and then automatically switch to DC when the AC is no longer working. It will also sense the resumption of AC power and automatically switch back to AC making it ideal for high hurricane areas and places where power disruption is common.
