Hotpoint HS93X cooker hood. 39262 Serial no:- 607030041.
The PCB had been blown by a lamp failure. No power to the lamp holders and the fan only operated on one speed. OK, I thought, new board should sort both problems!!
Not so….lights work now but still no speed control. 😕 Does the PCB control the speed of the motor or is it done by another component? Short of dropping the fan motor assembly, I can’t see anything else that could be the speed control.
Any ideas or a wiring diagram would be much appreciated. If another component is involved, has anyone got the part number?
Thanks,
Steve.
