The Dometic fridge fitted to Molly is a three way version that needs to be manually switched between modes, gas, electricity or battery.
When away and on EHU the fridge is switched to electricity and it will act normally. Cooling and maintaining what we set it to.
We have used it on gas a few times but if we have EHU it seems best to use it.
The problem we have encountered is that after days on EHU and the fridge has been working, and we are on the road, the fridge switched to battery, after about 50 miles the alarm goes off.
The battery setting doesn't do anything but maintain the temperature in the fridge. It's this that's seems to be the problem. The power comes directly from the engine alternator.
We were prepared to leave Molly there but they had it looked at whilst we waited.
It's apparently an Elddis "known problem". The fuse between the engine bay and fridge is too lowly rated and gives up after a while.
The fix is to uprate the fuse and problem solved. We hope.
Fingers crossed we don't have that irritating "beep beep" all the time when on the road.
