I will have a look at the cooling fan option after I have cleaned it all up and put some cooling fins inside.

Thanks

The three way fridges used on caravans find greater performance with computer fans .
I am certain this will not help the finch fridge .
there is plenty of ventillation in the back of it.
I find packing gear around it in the back of my vehicles doesnt affect the performance to any noticeable degree.
Operation on gas is the go !
Mine I leave on gas whisle driving in the back of the defender or 101 with no problems.
The only common fault which I know of is the sliding plastic cover over the controls can melt .
I never cleaned the burner on mine or had any problems other than the gas regulators on the bottle playing up.
Some times they can be a bit hard to get lighted.
Learnting where to adjust the gas control knob takes time too.
As made they came with small ice cube trays which sit on top of the cooler plate.
These small trays full of water or ice improve the surface area of the plate and help the whole thing work better.
These trays most likely would have been lost ?

Well the fridge is working OK on 240v - now maintains -5 and is trying hard but not quite freezing 400ml of water (ice has formed but not frozen through) - works just a tad better than my 12v cooler/warmer.

Gas will seem to be the go and I will try that this weeked.

Thanks to everyone who has provided advice and input.

Gary, also check the door seals properly - it's amazing the amount of energy that can be lost through a badly sealed door.

If it's going to be a bush fridge - think about putting clamp type closers on the door - not attractive but bloody effective.

With Absorption fridges it is critical that they are level.
Get a small spirit level (circular with bubble in middle)& epoxy to top.
Get a 12V fan from an old computer power supply or new from Jaycar & mount under middle of evaporator (the finned unit you can see thru vents at top of fridge).
Mount so that fan blows up towards centre of evaporator. These 12V fans draw only 150ma but dramatically improve cooling efficiency of absorption fridge even when run on gas. Mount a socket on rear and wire to fan.
A cord with cig lighter plug completes setup. Power drain is so low that you can leave fan plugged in for days without any serious discharge to battery. 24hrs X.15A is only 3.6AH.

Hi Bruiser,

Any chance of pics?
