Frdige Performance

I have done a search.....and found lots of useful fridge advice.

The fridge (Electrolux 3 way 17 yrs old) works on 240v (I say works buts that is the point of this thread).
It also "works" -but not so well on Gas (suggesting my jet is clear...?) (i am not expecting much from 12v......0

It spent the last 6 months upside down inthe garage so has had the coolant agitated to celar blocakges.

I have tried to seal round fridge so air can only come in at bottom and out the side vent.

On 240v
Making sure the van is level I managed to get 0 deg in Ice box and 12 deg in fridge with an outside of 15 degrees
When the van reached 25 degrees inside - the fridge was about the same (0 deg and 12 deg). I did get the ice tray down to -5 degrees overnight though.

On gas - the performance is a little worse (typically a couple of degrees warmer - to the point where you saw little difference between outside temp and fridge temp.

Any ideas why performance could be so poor (or is this poor?....) on both 240v and gas. The heat exch certainly gets hot at he bottom (and warm a bit higher but only slightly warm by the time you get to the bit behind the vent/grille.) Does this suggest blocked channels in the coolant meaning it is only perhaps getting to the freezer bit.....?

Your Ideas please :D

Optimal performance is on 240V mainly because it is thermostatically controlled. The freezer compartment is basically the sole source of keeping the entire fridge cool and any items in it (simply put - heat energy travels from Hot to Cold). With fridge on 240V and after 30 minutes or so, check that all the pipework and fins are getting hot but take care not to burn your self. You also need good ventilation around the fins for the fridge to operate efficiently in warmer temperatures. If the ice box is getting to 0 degrees then it is working and these older absorption fridges are not brilliant in warmer climates

they are supposed to be most effecient on gas as there is more /even heat distribution.

had this prob with mine recently , stripped evrything down , cleaned the jet/pipes ect , didnt work any better the first time, but 2nd time sorted it!

was freezing the stella at big bang last weekend in the ice box!
make sure the swirly deflector is fitted in the gas tube and yes these older fridges are tempremental about being level
