Hi everyone,
about 2 months ago my dryer started having problems. It would occasionally not work and create buzzing noises as if it's trying to start. We opened it up and saw that there was dust everywhere (assuming this was causing some sort of overheating) and vacuumed it all up. We also replaced the drum rollers as well as the rear drum seal, but it still made buzzing noises. So recently, I replaced the thermal fuse and high limit thermostat, but I'm still having problems. Anyone know what it might be?

Thanks in advance.
