Kurt K La Center , WA September 19, 2014 Appliance: Maytag Electric Dryer DE312 Maytag Dryer De312: Motor failure noisy squealing bearing followed by failure to run buzzing noise when start pressed. How to replace Drum Support Roller. This was a Maytag DE312 actually a Whirlpool labeled as Maytag) and is 27 years old. Replaced motor, drive belt and drum rollers. One tricky part was the motor because the new motor comes with integral starter and it was necessary to cut off existing female spade connectors on some wires and crimp on new connectors. Instructions were adequate but need to be carefully followed and a decent electrical stripping and crimping tool must be at hand. I bought a new motor drive pulley because another user indicated the hex set screw was difficult to remove and all went well. The belt installation always gives me fits but if you are patient and look carefully at the supplied instructions it can be completed with some effort. Note that the grooved side of the belt mates with the pulley and the flat side runs against the drum. It is also very helpful to have the right snap ring tool because they are very difficult to remove without the proper device both for the fan removal and the drum rollers. I used a Dremel tool with sanding disk to reduce diameter of the pins on my snap ring tool to fit holes in snap rings which worked OK. This is the second repair on this dryer (replacement of heating element & drive belt) and all went well and she is up and running again. 98 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
