MED7230HW4 Whirlpool Dryer - Instructions

Unplug dryer from 220VAC outlet

Remove bottom cover panel, slip a flat blade screwdriver into each clamp, and bottom piece becomes removable. Pull forward and lift bottom cover piece.

Pull up top section from dryer frame. Disconnect dryer door off/on contact three wire switch by pressing plastic connector together. You may need a small flat blade screwdriver to seperate connector.

Remove two Torx (T15 head) screws in the far left and right corners of the front door panel.

Remove two screws underneath dryer lint screen, be careful to not let front door and front cover fall forward. The rotating dryer drum will now be loose.

Underneath drum, there is a cover panel over the dryer motor. Likely you will find a bunch of lint all about. This dryer had likely not been cleaned in many years.

Remove screws on dryer motor cover.
Remove panel. Likely, you’ll more lint about.
After vacuuming, use a flashlight and hand mirror to locate belt tensioner, back side of motor. If your belt is not broken, press down on the tensioner spring and remove belt from tensioner and motor. Inspect belt, replace if worn. In this instance the belt was well worn.

Slowly pull dryer drum forward, walking belt along as you bring drum forward out of the dryer casing.

At this point you have plenty of room to access the one bolt holding the tensioner, in this instance it was a 13mm socket. Be careful to remove the tensioner springs before removing the bracket. Your PartsSelect is an identical match to the original one.

Install new tensioner, tighten slightly, then put springs back on.

Reverse this entire process to get your dryer back together and back running smooth and quiet as it was when new.

This dryer was quieter than its owners remembered it being back when new 15 years ago.

Well worth saving the $ doing your own work.

Good luck on your repair endeavor!

Removed the front panel, removed the tub and removed the old seal. Tub seal area was scraped, sanded and wiped with acetone to ensure a clean. Bonding surface. Applied adhesive with and acid brush to get a consistent adhesive layer without getting too much in any one place. Seal was a bit smaller than the tub circumference so it had to be stretch to fit. While the adhesive was curing , I took the time to clean the contact surfaces and vacuum the lint from inside the cabinet. Reinstalled the tub, drive belt and front panel.

Followed standard instructions regarding removal of top first & then the front panels. Realized after following this process that I did not have to remove top, but only one of front panels to obtain access to moisture sensor. If I have to do this again, the replacement of sensor will be much easier.

A) Watched video of repair on site.B) Looked around for competitive prices and decided on PartSelect because of original parts, price, and 1 year guarantee.C) Proceeded to take dryer apart like video showed. Error was my dryer front panel has two screws covering the heater box and that was all I needed to remove and replace heater instead of dismantling the back. Good news though was, I removed all the lint build up in the machine so not a waste of time. Be sure not to touch the new heater wire coils as oil from your hands will destroy the heater prematurely. Heater was original Whirlpool ! I'm a happy camper.

Followed instructions for standard blower wheel replacement and repair kit installation, which were straight forward. The only real issue I ran into was removing the blower wheel, The instructions say to turn it clockwise and remove it, however this wheel had been on there for a long time and it also has a taper shoulder so it was not coming off without a fight which is why the dremel tool is listed. I had to cut the old bower wheel out in pieces so I could remove the electric motor, which was easy. Once out and on the bench and only the metal hub left on the shaft a 7/16" wrench and large vise-grips got it to break loose. The good side of this is it allowed me to blow out any lint that had built up on the motor, like new again.

To replace the light bulb, I removed the screw and the cover, unscrewed the old bulb, replaced with the new bulb and replaced the cover, securing it with the small screw. It worked appropriately with normal use for a few days and then I noticed the light was not coming on when I opened the door.

I removed the cover and pulled out the bulb to find that the filaments inside are dangling and burned through. I need them replaced, please.

The repair went well, using the whirlpool repair manual and looking at the video from PartSelect. The machine was a bit different than the one in both the video and the manual but that did not cause any problems. The only tricky part was to reinstall the belt "blind" behind the motor, easy to pinch your fingers and also get scratched by the sheet metal edges. To make it easier for that part I supported the drum with the old belt and a bungee cord to the garage frame so I did not have to hold it up and work under it at the same time. When the drum and new belt were in place I just cut the old belt, it was going to the trash anyway.. I replaced the belt and the tension pulley, witch was not turning easy and worn by the belt. I also put some grease ( SUPER-LUBE, www.super-lube.com) on all pulleys. It took about 2 hours because I am 78 years old and have heart problems.

I followed the video provided by ‘Partselect’; although it was not the exact model it was close enough to get the job done with high confidence.

Just follow the repair video, it was easy!

replaced dryer lint screen with new.

Removed the top, removed lower front cover, removed the front, removed the belt, removed the drum and the back. Removed and replaced roller support shaft and drum roller’s. Completed all Front and rear support for drum. Replaced drum , replaced drum roller belt and replaced back, completed replacement of the top, front.

Couple screws behind the electrical panel at the top and the top pushed back and was able to remove front panel, and then it was pretty easy. Take the two screws on top front, lint trap screws . The lint trap vent needs to come off. Then the belt, drum comes out to access the idler pulley. I did replace two drum wheels, I saw there was 5. I would recommend replacing all of them, they didn’t move well…..

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.

Followed the instructions all went good except for the sliding the shield back in it didn't want to go back in but it does fit. Dryer works like new again.

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.
