Mrs complained that dryer drum stopped rotating and there was a buzzing noise and slight smell of electrical burning. Before these symptoms the user pressed the start button, there was a delay of about one second and an associated kind of buzzing sound before the motor kicked in. With the tumble dryer moved to the garage (and empty) I tried to replicate the fault without any consistency (sometimes it would be fine others not). With the lid removed I applied slight resistance to prevent the drum rotation and the symptoms returned. Not aware of any particular bearing noise but was wondering if a damaged bearing would offer enough resistance to prevent the motor from kicking in. Any ideas or tips greatly appreciated.
