I sold someone a fan for his CH boiler a couple of months ago and he
swears that it causes RF interference. I sent him another one which he
says is OK. We've also changed his pcb for him (to eliminate the
possibility of it being a relay problem

Now given the fact that it's a shaded pole motor and the connections to
it are sound (i.e. electrically, it's just a coil of wire) does anybody
have an explanation ?
