Might be a difficult one this!
An old electrolux fridge. Works fine on Gas and 240V. It seems to operate poorley - if at all on 12V. It is difficult to tell if it is completely non-working as I have not really done a comprehensive test.
The situation is that depite being pre-cooled on gas overnight, after a 4 hr journey fridge is considerably warmer - to the point that it feels like the contents are keeping the fridge cool rather than the other way around!
The thing is the electrical side checks out OK, removing the 12V fuse to the fridge and putting an ammeter accross the terminals shows the expected 8 or 9 amps draw from the car. This suggests that the 12V element is working correctly.
I did once try the fridge on 12V from warm, and after 5 mins there was no noticable reduction in temperature - even on 12V I would have surely expected at least some signs of coolness in the ice making compartment at least?
Is it possible for the heating element to become detached from the 'boiler' part of the circuit and thus be working but not heating the refrigerent?
Any other ideas?
