MED7020RW0 Whirlpool Dryer - Instructions

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.

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

Turn off electric to unit.
Remove lint trap.
Remove lower cover below dryer door. 1 grey clip on either side. Bend upper portion of the clip down while pulling forward on panel.
Remove 4 1/4 inch bolts that hold blower duct to fan.
Push pulley upward while removing belt.
Use a small angled pick to remove pulley lock ring.
Install new washer and pulley. I added grease to pulley shaft.
Hope this helped. Good luck

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.

I took off the back panel off the dryer. The idler pulley could be accessed on the bottom. It was a bit cramped but not too tough to replace.

first of all there is no video for this model dryer (cabrio accu-dry) the main difference is that the console is removed by removing 3 screws across the back top of console then using putty knife release spring fastener on each side ,slide forward and lift. remove one screw at top of control board and remove from plastic mount,and unplug connecting wires.remove top of cabinet lifting up and forward. The rest of install is typical to other models. The back panel doesn't come off this model. You have to access everything from the front.

Took door off with a Phillips screwdriver went to hardware store with door so he could match up the 6pt screwdrivers that were needed.
No more then 1 hour to do.

Disassemble dry. Put on new pulley wheel. Greased pulley wheel. Put dryer back together. Works great. Yours truly G.B.

pull the back off and replace the pulley.

Took back panel off, and it was really easy putting the new idler pulley in.

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.

I ordered the part(and a backup) and had it in two days. 5 days less than ordering from sears.

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.

The first thing I did was to watch the video from Part select on How to change thermostat cut off switch and the high limit thermostat fuse.I did not have a meter reader I just brought the thermostat cut off kit for about $ 32.00 dollars from part select and replace both part's and my dryer still was not getting hot so back to part select video's I looked up the video on replacing the heater element and I ordered one for about $ 97.00 with shipping I replaced it and put it back together and it worked it took just a few hours . I would like to give Avery special thank to part select for the video help and for having the parts for a great price again thank you so much.

Followed your video for replacing the Tension Pulley, Drum Belt and Drum Rollers. Models were not exact, but instructions were very clear and detailed enough for a "computer geek" to do the repair myself (with some help from my wonderful wife). Live in Ohio, parts came from Kentucky and I had them the next day! The dryer is almost 10 years old. Running great now. Thank You!
