Frigidaire dryer rumbles and shakes
« on: August 20, 2020, 02:09:06 AM »

Frigidaire model flsg72gcs9.

The dryer would not start so I took the front panel off and saw that the drum glide felts were damaged and coming loose. I replaced the top and bottom felts. I stretched the bottom felt too much when installing and snipped off about a 1/4 extra. After reinstalling, the dry went for about 15 minutes before a low rumbling could be heard which got louder as it went on.

I took the machine apart and noticed the pulley wheel had a crack so I ordered a new one along with a new belt. Replaced them and got the same result. (the belt leaves shaving or rubber dust underneath the pulley)

I ordered a new drum bearing even though the old one looked good and replaced it. Same result.

At this point the motor would not turn without assistance so I thought it was bad bearings and installed a new motor (and blower housing it comes with). Same rumbling, maybe even worse.

I noticed when I pushed on the back of the dryer the rumbling would stop and noticed on one of the corners it was missing a screw. I had to drill through the hole to get to where it secures the intake to the back round plate. Still continued to rumble.

The rumbling did not start until after I installed the new felts. They have had to be replaced a few times over the years. The left side of the felt has rubbing marks because the drum leans to one side creating a gap on one side and rubbing against the other. But I think it has always done this. I have leveled the dryer but the drum still leans that way.

Whenever I reinstall the drum it runs fine for 15 min to 45 min

The only thing I have not replaced is the blower fan but the dryer runs fine with the belt off and starts rumbling as soon as I put the belt back on.

Any ideas?

An error occurred. Can't hear a thing.

You more than likely have a stripped blow fan wheel around shaft of motor. Typical in those Frigidaire Dryer Blower housings!

I replaced the fan and the rumbling is still the same. I think I have replaced every part on this machine. I believe the drum or housing may be warped. the drum rubs against the left side of the lower felt. I have put a plastic tube on the back of the machine and pushed it against the back wall and this minimized the rumbling but there is a squeal now. I wonder if it is possible to mount some kind of wheel like a drum roller on the side so that I can center the drum?
