Halstead Hero 90

[cheeseman]

Hi,
I have a Halstead Hero 90 boiler approx 6 years old.
It would seem that the fans electro magnet has over time become permanently magnetized therefore during its start up process the fan does not spin and the boiler goes to lock out. Given a helping hand to get the fan turning it spins as it should and the boiler will fire up, although when the thermostat cuts in to shut down the boiler, the fan has this residual magnetic resistance and won't start again unless assisted.
Is there anyway of dissipating the magnetic charge thus allowing the fan to spin freely as it should when the boiler is off?
Many thanks

it's a shaded pole motor and it sounds like the coil has gone.

fan needs to be replaced (halstead, so will be twice the price of anyone else) although you may be able to get a reconditioned fan for a lot less.

you need a registered installer to do this. don't think he/she is ripping you off when they charge you £180 for the parts. a british gas fixed price repair may be your cheapest option.
