Dometic Fridge 2019 Elddis Affinity 554

I bought the caravan new.  After 6 months the fridge stopped working.  Two and a half months later I managed to get it fixed with a new PCB.

Now, the caravan is 2 1/2 years old and the fridge has packed up again. ( Once again in the middle of summer.)  I have to wait over two weeks for it to be inspected and am told that replacement parts could take up to 46 weeks!  The dealer says it is out of their control.

Anyone else with this problem?

I don't want to use the caravan until it's fixed.... any suggestions?   I can't even sell it in this state! which I now wish to do. 

Also, the caravan had to be returned after its April service for the front windows hinge bar to be resealed.  My neighbor who has an Elddis Avante 2018 had the same problem.
