2008 Dometic trouble

Reevco

We are on site at the start of a 3 week stay and the fridge has stopped working.

Mains 12v and gas

Had Fridge out today, checked the following:

Fuses checked at fuse box and fridge

240v heating eliment giving around 300 ohm

240v getting to fridge

12v electric getting to fridge

12v towing getting to fridge

Gas getting to fridge ok.

I'm normally good at fault finding but this has me beat I thinking it must be the main control panel itself on the frigde has anyone else had trouble like this
