My 05 plate fridge does not work. No fan, no light and no cooling nothing. I have removed it and the unit is getting power, if I put power direct to fan, cooler and even light they all work fine, so does the on/off button when tested. So I've successfully narrowed it down to the circuit board however this is about the limitations of my electrical skills. 2nd hand units are only £100 + but as I know the internals all 'work' it would be great to fix my own. Has anyone repaired or do repairs on these units or have any suggestions on common faults on the circuit board? I'd love to get it working again.
