Thetford Fridge!

Fezzer

Hi. I have a Thetford N80 fridge in my Elddis which has stopped working. We have had the van 10 years now from new and the fridge is not working, certainly not on gas. I have researched a new fridge and cannot believe the price to replace it, just short
of £800 which I am loathed to pay. I am unable to find any second hand fridges of this particular model whatsoever. Could I please request suggestions of what to do, am I able to replace it with a different cheaper make? It has the step at the rear of the
fridge for the wheel arch. I would appreciate any help. Thank you.
