Have you tried contacting apluljack regarding a repair of your control ? the one shown that they repair in their catalogue looks very similar to yours.

As far as I know they are discontinued, then only option might be a repair.

The components are all standard stuff but it’s finding the failed component that’s causing the problem is the difficult bit.

If I remember correctly te board is on a split level, what is the reason for needing a new board? What’s not working?

The top circuit board has a burn on it so yes maybe can be repaired
The red part in photo is gone and is black

The red component looks like a varistor (mov) they are there to protect the board from over voltage and go short circuit.
So it may work again just to test it if you snip it out. What are the symptoms on the fridge?

I have not AC power when I plug it in it blows the fuse and trips
I think I need a new fridge but finding one to fit is my problem
If anybody knows what model this is I would appreciate it as the model tag is not readable

The repair mad has told me that it is unreparable as it is covered in glue and will not be able to remove the bottom board

If it trips on electric hook up, that is probably just the heating element blown

Sorry been painting the outside of the house! I hate painting!

Funny that because I love my watercolour painting.🤣

The red thing as stated above is a varistor, it’s probably short circuiting.

There is a guy on fleabay who does repairs like this but I can’t remember his details.

Will keep looking 🤔

Thank you I have ordered one ...no harm in charging it and see what happens

Dominick Do what Richard n Ann said. If it then works, you just need an electronics engineer to replace the varistor.

Failures of these devices is common. It has done it's job.

Just snip it out (at least one end) and try it. It will run without the varistor protection. Then you will know if there is any other damage.
