Dryer is occasionally leaving rusty looking smudge marks on clothing.

your clothes are getting caught between the drum and the rim due to bearings out of the wheel guides. These guides are what the drum rests on when it is turning. Most dryers you can access these guides by taking the front off the dryer. Not a big expense just a little difficult to get to .

The first thing to check if the vent. If the vent is clogged then the dryer will get too hot. http://www.appliance-repair-it.com/clothes-dryer-repair.html

The dryer is prone upon leaving marks on clothes. The felt band surrounding the drum has worn out. Replacing this felt band will keep your clothes streak free again

Usually, if you are getting brown streaks or marks on clothing, one or both of the drum seals are going bad. Clothing will drag between the bulkhead and the drum, leaving brown marks. If you want to do the repair yourself, I can provide instructions, otherwise call for service.

it sounds like a drum support roller is going bad or the belt idler pulley. i think maytag has a kick panel on the bottom that can be removed. look inside with a flashlight and you may be able to see something. if not, you may have to take the drum out to get a really good look. make a note and study how the drive belt serpentines around the motor, pulley, and drum so you can get it back together.

Are you using a liquid fabric softner ? If so , rewashing the clothing may remove the marks . Use dryer sheets (softner) instead .

you might need to replace the felt on the inside front that the tub rides on

those "burn" marks if they have an arking shape to them are smudges from the felt that goes on the drum support above and bellow the door inside the drier. the felts wear out every five to seven years or so. easy repair. send me a model number and i could go into more detail. part numbers ect.

throw a clean pair of old sneakers in the dryer with the clothes. this should not allow the clothes to stay in one place during the entire dry cycle

Take a look and see if the drum near the door moves up vertically. It shouldn't move more than 3/16ths of an inch. If it does, replace the upper felt seal/plastic slide. The upper seal that supports the front of the drum on the front of the dryer is worn out to the point that clothes can get stuck in the gap between the drum and the front of the machine. This leaves brown wedge marks on clothes. While it's apart, replace the lower felt seal as well.
