The high pitch squeel was the result of a failing drum bearing. It was particularly evident when first turning on the dryer, but became softer as the dryer heated up. In order to replace the drum bearing, I removed the top panel and front door panel.

The top panel was easily taken off by removing 2-screws from the back edge o ... Read more f the panel, and sliding it back to release it from the front panel seam.

The front panel is more involved, but still relatively easy for your average "do-it-yourselfer". I removed the front door panel by first removing the control panel (4-screws; 2 on top and 2 from the back of the panel). I removed 2 cable assemblies from the control panel via connecters (different sizes so didn't need to mark) and 2-wires attached to the large control panel mode selector (I marked these 2-wires). I set aside the control panel. I removed the front door panel by taking off 6-screws (2 on top, 2 on the bottom, and the remaining 2 on the inside of the panel on either side of the drum). After removing these 6-screws, I carefully pulled the front door panel away from the front of the dryer, carefully releasing 4-alignment latches (2 on either side). The front door panel was still electrically attached to the machine so I had to disconnect a couple more wires. I carefully disconnected 2-wires from the door light assembly and 3 more wires from the door switch (I marked the 3-wires on the door switch). I set aside the front door panel.

From the back of the dryer, I removed the small motor access panel on the bottom left corner. This panel also provides access to the drum belt. I released the drum belt from the motor drive wheel by releasing spring tension at the tensioner. The belt can easily be disconnected from the motor drive wheel and tensioner assemblies.

Removal of the drum was now possible. With the front door panel removed, the front of the drum is maintained in place via a small plastic stop on the top crossmember. I removed this stop prior to removing the drum. With one hand, carefully grabbing the belt that is was loosely draped across the back of the drum, and the other hand holding the front lip of the drum, I provided a quick and forceful upward motion to the back of the drum in order to dislodge the drum shaft from the bearing housing assembly. Once this was accomplished, I simple pulled the drum out of the dryer housing via the front of the machine.

The drum bearing repair kit ordered came with the replacement ball bearing, bearing housing, drum shaft, high-temperature grease, and attaching hardware.

I replaced the drum shaft on the drum via the 4-screws accessed on the drum rear panel.

I removed the old bearing/bearing housing via the 2-screws holding it in place. I wasn't too concerned about loosing the small ball bearing as the kit provided me a new one. I generously applied some high-temperature grease to coat the interior lining of the new bearing housing. I also placed a dab on the back seat where the new ball bearing sits. This helped hold the bearing in place while reattaching it. I reinstalled the bearing housing to finish replacing the repair parts.

Reassembly of the drum is in the reverse order. I paid particular attention to making sure the new drum shaft properly seated with the new drum bearing housing.

After reinstalling the drum and while the front door panel was still off the dryer, it was easy to inspect the blower housing. I found the squirrel cage had broken loose from the molded nut that attaches it to the motor shaft. That would explain the heat problem; the heat was not being exhausted through the duct.

THE SQUIRREL CAGE IS REVERSE THREADED. I was unable to remove the nut from the motor shaft as the design encompasses a metal bushing molded into a plastic nut shaped form. The plastic would not hold up to the force I was applying trying to loosen the squirrel cage. So I ended up removing the entire motor and blower housing assembly from the base

Fixed it eventually with part PS470049 ('M' Series Ignition Coil Kit). See separate story.

The flame sensor did not fix it but read on for info on how to replace this part. Before replacing this part, I should have read another posting in a different web site about the ignition coils: if you see a red glow inside the burner uni ... Read more t but the flame does not come on, then the problem is likely to be with the coils, not the flame sensor. However since some users here had solved the problem by replacing the flame sensors, I figured I'd try it. The setting for "More dry, less dry" never worked either so maybe this would fix two problems at once.

This dryer is a stacked front loader sitting on top of our washing machine. Opening the little front door (lower left side) is easy once you figure out that a little screw below needs to be removed. I almost broke the door trying to pull it open. The sensor is attached to the side of the flame area cylinder. It was hard to remove both the screw and the part itself from the slots as it's very springy. In fact when I finally removed it, it dropped to the base of the unit and sparks went flying as one of the electrical clips touched the metal (ground). Tip: first disconnect the electrical lead coming from the back of the unit to the ingnition block and later I used rubber gloves just in case. (I could not access the plug/outlet in the back). I installed the new part easily, though I was confused by the electrical leads: the white wire connects to the lead that has a red plastic dot on the side, but I think that must be a mechanical part and not a (wrong) marking, while the red connects to the other lead. Anyway, I connected it the same way I found it and put it back. Reconnected the other electrical wires and closed the door.

This did not fix the problem which turned out to be with the gas valve coils: as they get old, they turn off the flame when they get hot, even though the dryer keeps on turning. To read how to replace that part, search for comments under part number PS470049 ('M' Series Ignition Coil Kit). I don't know whether replacing the flame sensor is going to fix the "more dry-less dry" function, will have to see. Still, this website is great. Our dryer is a Westinghouse bought in 1991 (almost 20 years old!) and with this fixes it's just like new.
