Start Winding Dryer motors usually have 2 windings a Start and a Run
At motor start both windings are on once the motor gets close to its run speed the start winding is disconnected.
This is usually done by a pair of switches on a centrifugal speed mechanism, this is part of the motor.
It could be that this mechanism is just dirty, clogged up with lint
One of the switches has failed
Start winding has burned out
I'd try cleaning the motor out first |
