4KMEDC420JW0 Maytag Dryer - Overview

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

The issue was the idler pulley. First I began opening up the front panel based on a youtube video but soon realized the model was slightly different and required a lot more items to remove. I saw the pulley in the back with nothing in the way so I put the front panel crap back on and removed the rear panel. There it was, very simple to remove and replace. I'm not looking forward to drum rollers though. Hopefully they're aren't as difficult as they appear.
