Re: New fridge in new van not working
Hi Russell,
As OT said the fridge needs to see 12V but it is a separate 12V called the D+.
Firstly if it is trying to use gas when the engine is running the fridge is not seeing that the engine is running so the D+ wire is not connected or livening up.
These AES fridges need to have two 12V supplies plus another positive 12V called D+.
1. The big 12V from the Anderson plug is to run the fridge heating element this is the main supply.
2. The little 12V supply usually from the van 12V battery this is for the fridge electronics. This supply must always be available or the fridge will not work.
3. The D+ supply is used to tell the fridge the vehicle engine is running and the fridge can then use 12V. The D+ is a separate wire run from the tow vehicle to the fridge and usually looks at the vehicle alternator and if the D+ is outputting then the engine is running. Usually you can find a fuse or wire in the vehicle that only is livened when the engine is running to connect the D+ wire to.
Why the gas is not lighting is a mystery. The fridge should run on gas if it has gas has a spark and naturally the little 12V is available which it should be or it would not even work on 240V if the 12V was not there.
If you can hear the ticking noise from the spark it real sounds like there is no gas.
