For the last year its has only been working on #3 highest, but today even that has failed.
So taking the statement from Fezz below from an earlier thread
"There isn't a speed controller on the fan. It's simply two 25 watt resistors wired so that the lowest speed setting runs through both, middle through one and high bypasses. they then feed into a connector to the fan. I'd start checking that connector and the neutral line coming off the fan."
1. It would seem that the resistors are knackered, these can be replaced without too much trouble, just time and ripped knuckles getting it out.
2. Something else is knackered. Would this be the fan itself, it had started to be noisier? If so then what type/product of fan should one be looking at as a replacement?
3. What else could be broken or needs to be investigated?
(NB. Wiring and connectors all seem fine, there is power to the fan)
Thankyou for looking.
