Okay so replying to my previous post, you have had it working previously on all three power sources before so it's not a problem related to power. I have heard that the ammonia can settle and become dormant if the fridge hasn't been used for a while that's why I asked if you have had it working before. I believe this is an old remedy to get the fridge functioning again and I do know that this method did work for a family member with an 80's caravan many years back. What you have to do is remove the fridge from it's mountings and check to see if there is an ammonia leak first which you should be able to detect by a strong smell. If there is a leak then unit is not sealed and will require a new unit. If no leak is detected then agitate the ammonia solution by tipping the fridge upside down amd leave it for about an hour. Turn it back over again for another hour and then turn it upside down again and leave it over night. The next day turn it back over, re-fit the fridge and operate it on GAS only as it gets colder quicker by this method and will immediately activate the ammonia. If it does get cold then leave it connected on the gas for a day or so to keep the ammonia circulating. It may work and it may not but I have provided a link to show basically how a caravan fridges work, how to best use them and what can go wrong.

Hello there
Dont forget these absorbtion fridges need to be level.

Yes that's another valid point to be taken into consideration but I didn't mention this due to the fact that it's a motohome with 4 wheels and not a caravan with 2 which can be unlevel from front to rear. If your motorhome is on a slope at all then yes this can affect the operation of your fridge so make sure you are on level ground first.

I don't know whether we've just been lucky but we've never had any issues over the fridge needing to be "level"...and we've pitched up on some really sloping festival sites...

...we've always found that,as long as the van is at  a "liveable" angle,then our fridge(or rather,fridges)have worked...
