As recommended on this forum, i've fitted a small (60mm) computer fan to extract warm air from the fridge compressor space. The fan works but doesn't run very fast, so doesn't move much air.
The fan has 3 wires- live / neutral / and a 3rd which i suspect is a control wire. I suspect the 3rd wire is used to control fan speed, but i've nowhere to connect it, so it's redundant on my set-up
Does anyone know for sure what the 3rd wire is for and has anyone faced and solved the problem?
