Squealing noise when running, bad motor bearing; needed new motor.
The instructional videos that this site provides are really great and most helpful. If changing a motor or blower, it will tell you to hold the motor shaft while loosening the blower, (CAUTION: left hand thread). Those instructions would be great for a dryer that is almost new but the likelihood of needing to change the motor or blower wheel on a fairly new dryer would be slim. Because my dryer was not new, as I suspect most needing repairs aren't, I ended up doing what most everyone else had to do and that is,cut the shaft that extends into the blower wheel because that blower wheel absolutely refuses to break free from the motor shaft, most likely because it's seized onto the shaft, probably caused by years of moist air in the blower tunnel, (too bad the factory doesn't put a dab of Never Seize on the threads before assembling it when new). In any case, if you determine that you need a new motor, do yourself a favor and order a new blower wheel at the same time, then plan on cutting the old one off if it fails to budge on your first attempt. I used a Milwaukee M12 Hackzall, which is their smaller mini cordless reciprocating saw, with a 6" blade. A six inch blade is just long enough that it will flex, allowing the space required to get in between the blower and the end of the motor. You might be able to get a full size reciprocating saw in there although it will be tougher. Be careful not to destroy the felt seal on the cabinet wall that keeps the lint out of the main cabinet. Once the motor and blower are free of each other, the rest is simple and quick. If I spent two and a half hours completing the repair, 90% of that was trying to unscrew the blower from the motor. This site is great to do business with, from their large inventory, to their great web site, service, and delivery. Great company!
