Eric T Columbia , MD December 22, 2018 Appliance: Model WHIRLPOOL DRYER I THINK Dryer squeaking loudly!! / trash compactor switch bad as well I diagnosed the squeaking problem years ago,and sort of forgot about it. I had sprayed some form of lubricant on the roller bearings. When I was repairing my mothers furnace, I heard the dryer again. It had gotten much worse. I looked at A PROS website again. I love the schematics, they are very helpful I ordered the parts and fixed the dryer. She said it is like having a new machine in her laundry room.
