Re: w/pool american style dryer
These motors only seem to last 18 months to 2 years if in heavy use so it would be a good idea to take one along.
To get the fan off without breaking it first fit an adjustable spanner onto the pulley end of the motor to stop it turning then go round the back of the machine select a large spanner and jam it accross the fan blades.
Then use another spanner and large screwdriver as a tommy bar to turn the fan clockwise.
It will always come off in one piece thus depriving Whirlpool of another £20 of revenue 😉
