MEDB855DC1 Maytag Dryer - Instructions

I followed the very informative video and wrote down step-by-step notes for myself. The repair went very smoothly. The only thing I didn't realize, was that the dryer has 4 rollers, not just 2 shown in the video. All are easy to access once you disassemble. I had to do it twice since I had to order 2 more rollers in order to replace them all. Also, the triangle plastic washers come with the roller, so you won't need to order them separately like I did. I also changed the idler pulley roller while I was in there since that has bearings too. Just as easy. I'm very happy with my quiet dryer! One last note: The new rollers are a bit louder than normal at first, but they quiet down very quickly as you use the dryer. It must be because they are brand new.

Followed online video very easy and dryer works like new one....

The pulley is accessible from the back of the dryer. Disconnect the gas line. Remove all the screws. Also remove the small plate that secures the line cord. Lift the back up and out. I was able to avoid disconnecting the water line. Take a picture of the pulley so that you will have a record of the belt routing. Release the spring and remove and replace the pulley and bracket. Vacuum out the lint. Plug in the dryer to make sure that it works properly before reassembly.

Just follow the repair video, it was easy!

I pushed one end of the catch on upper side the hole and when locked, I pushed the other end of the catch to the lower side to get locked. To complete, the white cover was inserted on top of the catch and done.

Remove the protective cover on door with screwdriver, pop out the old catch, snap new catch in place, replace protective cover

Replaced door catch on dryer door. Followed video on Whirlpool website and it took less than 10 minutes. The dryer works great.

took out old ,twisted in the new one it was nice to have the right part the first time!! thank-you

I researched causes of the noise, zeroed it down to the idler pulley. I then got the dryer schematic and took the dryer apart after disconnecting the power and the vent. i did not have to remove the drum, the idler pulley was easily accessible once the top and back panels were removed. I simply removed the drive belt from tension off the pulley, removed the old pulley and installed the new one. Once finished the dryer was running whisper quiet.

Unplugged the Dryer first. Removed the two screws from the bottom panel using a 1/4 socket and removed the panel by pulling down and out. Reached behind the blower and removed the connectors from the old thermistor and then the thermistor itself by removing the two 1/4 inch hex head screws. Replaced with new part and after screwing back in, reconnected the wires and replaced the panel. From start to finish, it took me about 20 minutes.

Very easy repair... The video was really helpful too. I was able to find a different video that was closer to our model. (Front Loader HE) It probably took me a little longer than needed but I took the time to shop-vac everywhere I could, since it was all easy to get to. I opted for next day shipping so the shipping charges were more than the part. Tools I used were: Cordless drill-screw driver, 1/4in. socket, Phillips head bit and needle nose pliers for the control panel connections. Thank you again for making this so easy. Saved us a lot money by not calling an appliance repair tech.

Lubricated pulley wheel which temporary reduced noise. This verified what was making noise. Looked up the part on partselect.com and ordered it. Recieved idler pulley with bracket in just a few days.
Quickly removed back panel using nut driver with drill. Slipped belt off pulley, removed one screw with plyers to released spring and removed old assembly.
Inserted new assembly, connected spring, slipped belt back on roller.
Tested before replacing back panel.
All was very quiet. Replaced back panel.
All done

Unscrewed the inside part of the door from the outside door shell. Removed the broken pieces of the catch and replaced it with the new one. Screw the door back together. Did not need to remove the door from the dryer cabinet.

Message indicated something amiss in the motor circuit. Followed Instructions in the on-board manual. Turned out to be the internal-bias thermostat, and the exhaust air thermistor both. Changed faulty parts, cleaned lint from the system and we are off and running again.
Thank You.

I googled the problem and determined that the thermistor was faulty. I found your web site from which I ordered the replacement part. The part arrived within a week. The replacement was not particularly difficult, but the space was very tight (without removing more panels and covers). I just kept at it and got it installed and the dryer works fine now. There are several pertinent videos on you tube, none of which were my particular model, but the combination of them led me to a successful installation.
