I've got to start bringing a camera...
Called on Frigidaire electric dryer, older, basic, style (model tag removed). Complaint was it won't run, but we can hear it.
I hit the start button, and the motor hummed (not ran) while button is depressed. I opened it up, and it is FULL of lint. I had a hard time finding screws & wire connectors due to the lint.
Rotated the drum, & it was too stiff - probably just dragging the belt across the motor pulley.
I indicated this to the customer and removed the drum. The whole bottom of the cabinet, motor included was covered in 1-2" of lint. The motor would not turn. I removed it, took it to the shop & cleaned it up. Seized bearings. Can't replace those, (I had told cust. that he was looking at new motor before I left.).
Vacuumed & blew it out. took a toothbrush to the outside of bearings, and started treating it with Zoomspout Oil (thanks JW!!).
Worked it back & forth, while heating it with a heat gun on low. Got a bit of movement, then a bit more. Finally, after working both sides of both bearings, it spun freely. 10+ rotations a slap.
Took it back, installed it, and the dryer ran like a champ.
The dryer DID NOT HAVE a vent pipe. So it was pulling moist linty air back in. the lint on the motor was scorched!
I lectured about air circulation, humidity, and FIRE DANGER! (To the wife {spanish} also). You have such a pretty family. Dryers burn down houses if they're not properly hooked up. GET A VENT HOSE!
Couldn't guarantee the work, so if the bearings seize up again, we need a new motor.
But it ran, & no parts needed!
