I cvannot get the fridge to get cold. It comes on and then stops and will not click in again. It was working but defrosted and that was it. Is there a contact that can be reset and if so where is it?
I canot find diagramme for the compressor listed.

Hi Stephen,

If the compressor is not running the problem is electrical.  The compressor you have is an ACC (now Cubigel), they are good compressors and work in a very similar way to the Danofss which is more the industry standard.  Both models of compressor are extremely sensitive to the power supply, if the voltage on the battery is low, or you have a weak connection on the wiring between the battery and the fridge you can get a voltage drop when the compressor tries to start.  The Cubigel has a start protection system built in, so won't re-start for approx 5 to 6 minutes once it has cut out.

I recomment that you check that the battery is well charged  +12V and the wiring between fridge and battery is in good order, no corrosion or loose connections.

If I can assist further please advise.

Kind regards,

Zeb

Many thanks for your reply. Have checked wiring and fuse (15 amp). The fan comes on but it appears the compressor does not. (at least I don't think so and there is no warmth in it. After a while the fan goes off.
Is there a way I can check the thermostat is working as the switch is not easy to work and I would like to satisfy myselt it does work.
I do appreciate your help in this matter as living in West Cornwall I am not sure if there is an agent who could do it for me.

Hi Stephen,

The problem is electrical.  If the thermostat was broken the fan won't run.  You check the stat with a multi meter to confirm you have continuity (should make the circuit), or get a small piece of wire and bridge the connections for the thremostat (C & T).

Your symptoms are classic voltage drop.  The compressor is sensing enough voltage, so the fan is running but when the compressor tries to start there is a drop in voltage due to a poor or weak connection or under sized wiring.  If in doubt, run new wires from a battery that you know is fully charged.  Make sure wire size is correct and that connections are good - crimp terminals and correctly fixed to the battery - no crock clips!

I am pretty sure if you do this you will overcome the voltage drop and the compressor will start.  If it does not, it could be the controller which you can remove and sen back to us for testing.

Kind regards,

Zeb
