We replaced the thermal fuse a couple of years ago when it stopped heating up, but otherwise have had no problems. Over the last couple of months, it's gotten harder and harder to get the dryer to start. You have to push the start button for a couple of seconds before it engages, and the amount of time it takes to engage has gotten longer. Sometimes the first time you press the button doesn't do it, and it starts on a second try. I knew something was up, but all of my searching didn't turn up anything informative about a dryer getting harder to start. I warned my family and waited for the other shoe to drop... ... which it did this morning at 4AM, in the middle of one of several vital pre-trip loads. Sigh. Now the dryer just hums when I press the start button, but never engages. I've checked the door switch, it seems fine. The drum isn't stuck, it turns with a little resistance but that seems comparable to how it's always been. Any advice gratefully accepted! I'd love to get this back up and running for several more years!

The motor (Item 62 in the Cabinet Parts section at ~$105.00) may be worth replacing if the unit is in good shape. If you decide to replace it I would open the unit up and check the belt, the rear support rollers, the front support, the drum felts, the idler wheel. all internal seals etc. so that you have a total cost to do an overhaul. Also not that the blower wheel screws onto the motor shaft (reverse thread) and sometimes they freeze to the shaft and have to be destroyed to get them off. So get it to loosen before ordering anything.

I'm having trouble ascertaining whether there's any heat during those moments that it hums while I push the button - nothing seems to start up long enough to warm up. But it's been making plenty of heat as it started having more and more trouble starting up. I'll pop the back off later and start checking things out for electrical connectivity and visible damage. Now that I've messed with it a while during troubleshooting, after a few repeated button presses it doesn't always hum anymore - but if I give it a few minutes to recover, it'll hum again when I press the start button. Am I doing damage to something else when I push the start button while the motor is ostensibly dead? I've been rather confused by the behavior pattern (button took longer and longer to start the dryer turning, now won't start turning but just hums, sometimes won't even start anything). Is there perhaps something wrong with my start button assembly as well or could this still all be related to a motor failure?

When you hold the start button for a while and the motor does not start up. it's start winding is in the circuit and this causes the motor to overheat. the motor's internal thermal protect trips and you then have to wait for the motor to cool down so that the thermal protect resets. That is why I think you get no hum for a while after trying it a few times.
