The Fridge Freezer fan runs for a while having switched the machine off then after a few seconds switched on again, then stops never to start again until you switch off and on again. I’m blaming the rotary switch in the fridge behind the air passage trunking, it looks like a thermostat but has no capillary. Does anybody know the part No. of this thing. Also do you think I am on the right track, this stat looking thing seems to control the fan.
