My maytag neptune dryer seems to be leavin blue stains

The blower wheel on these tends to wallow out. That makes the dryer overheat and take twice as long to dry the clothes. Lint begins to build up in the filter housing. Finally the temp exceeds 350 and the round white fuse on the blower housing melts. Boom you has got a dead dryer. To get into the slopefront type dryer seems a bit intimidating bit really is not. Remove the door. The door is reverseable so 2 more screws opposide need to also be removed. Then the goalpost shaped front pops off. Then that reveals the top hold down straps. Remove them and top can be popped. Next you remove the front shroud the drum rides on. then get the drum out. Did I mention you do not work from the back at all on this model? Do not try to fix it in the wash room. Take it ouitside and put it on the picnic table or a tailgate to repair it. You will need a phillips head screwdrivers pliers 1/4 and 5/16 nutdriver and snapring pliers.
Shopvac to clean it up and probbaly a new fuse and blower wheel.

The small blue wheel, just next to the Motor, is the tension pulley, your belt should go around it, before going around Drum

my first guess would be something ,someone placed in dryer perhaps coveralls or oily clothing.There is no place that I am aware of on a dryer where you could pick up oil leaks from ..are you sure you did not have a lint fire,the oil stains may be soot

the problem is with its motherboard .. i too had the same problem.. ask the repairing persons to change the motherboard if it is warranted. ( but there is no other way)..

My best guess, is it is your blue jeans. fingernail polish remover..non acetone usually does the job. Stay in a well ventillated area when doing this. Good luck.

Give this site a try. Some guy on the forum had the Neptune issue and found a replacement seal. There are some how-to videos on YouTube(may not be your specific dryer, but same idea.) I'll let you have the joy of looking on YT.


Maytag Neptune Dryer MDE9700AYW Felt Drum Liner

I had this problem and the cause was a loose screw holding on one of the "paddles" inside the drum. I removed the door, front panel, lifted the top, manually rotated the drum until I saw the screw head which had worked loose and was slapping the side of the dryer. A quick tighten of the screw and the noise was gone.

Drum size or capacity for the Neptune Model Number MAH4000AWW is 3.4

you have to replace the back tub the bearing come built in the tub from the factory there is not any way just to replace just the bearings

This may be caused by some kind of wash product or softener product. You may be using too much. You can use a blue glass cleaner or small amounts of mild abrasive cleaner and water to try to remove it. Drums are made of porcelain or stainless steel and should 'never' wear out.
