Hi
Bathroom fan started oscillating on startup, for a few days it came on, went off, came on etc for a couple of mins before finally staying on properly.
Then it simply oscillated.
Took it out, need to replace CBB61 capacitor.
But I also noticed scorch marks either end of a resistor.
Resistor looks like it’s red, red, pink, gold under my microscope, presuming the pink is violet, (definitely not orange under microscope) then it should be 220 Mohm. But it measures at 22.72Kohm, which would mean the third colour is orange not violet, with the naked eye I suppose it’s orangeish
The scorch marks look to me like the resistor is getting too hot.
Any suggestions please (pics attached)
Thanks
