4KMEDC300BW0 Whirlpool Dryer - Instructions

The repair was fairly straight-forward. I removed the front of the dryer, lifted the top off, and then released the tension off the belt dy depressing the pulley arm. Once the belt was off, the drum came right out and then it was on to unhooking the wiring from the old motor. Very simple up till this point. The snag came when I went to unthread the impeller fan off of the old motor shaft. It was permanently sealed onto the shaft so I had to cut the old shaft into using a reciprocating saw was a metal-cutting blade. Once this was done the new motor installed easily exactly like the old one was mounted. I had to also purchase a new fan due to the fact that I was unable to remove the cut shaft from the old fan. All parts worked great and the dryer assembled back together easily. Works like a new dryer now.

First, let me say the t videos are excellent. Check them out if you haven't already.

I came across the video on diagnosing the causes of odd dryer noises. After watching that, I decided that the issue was probably a drum roller.

I took a chance and ordered the maintenance kit to avoid having to take the dryer part to confirm the diagnosis and then put it back together again while waiting for the parts to arrive (BTW - the parts arrived within two days of my ordering them) .

Even if you know your issue is only the roller, I recommend getting the entire kit. It takes no extra time to replace the drive belt and the idler pulley while you have to dryer apart and I consider it good preventative maintenance.

Definitely watch the how-to video PartSelect provides on how to perform the repair using the maintenance kit. It's very clear and very helpful. I'm not sure I could have figured out how the belt fit through the idler pulley without it.

As video shows, the repair is pretty straightforward. As others have noted, you'll likely find a couple of dollars in change and a goodly layer of lint in the bottom of the cabinet. Have your shop back handy.

It seems kind of silly, but I found the hardest part of the whole repair was getting the front panel to slide onto the two bottom clips that support it.

One thing to watch out for are two small metal clips surrounding the screw holes at the top of the front panel. The nut screws that hold the panel in place screw into these, not the panel itself. After I struggled to get the panel in place I realized that in the process I had knocked the clips off and so had to remove the front panel again in order to retrieve the clips from the bottom of the cabinet. Minor frustration. And with all the practice I had the first time around, the panel went on much more easily the second time :-)

It was very gratifying to plug the dryer in, turn it on and have it run perfectly. Better yet, it impressed my wife.

Followed the video .... Also installed another part. which was a kit. the video here showed the third wire being installed. The video on repair clinic did not show where to attach the third wire (orange wire). The Kit and the Thermostat was installed with 25 mins. Thanks

I have not received the parts yet waiting on the motor, can’t put the blower fan in without the motor, ordered it , Jan 23rd, still no motor, have to go to laundry mat, have you ever had to do that with 7kids, and you and your wife’s laundry, probably not, because you would have had your motor by now. Maybe you can help me with the part so I can redo a testimonial here for you. 19 days and still waiting

Perfect!

Be very careful of burrs on the edges of the steel inside the dryer. I cut myself badly when reaching into unplug the switch.
Procedure: Lifted the dryer top by pulling forward and rotating front up. Removed 2 philips screws holding the switch at the door. Reached into dryer and unplugged bad switch. Inserting small blade screw driver at the edge helped release the plugs detent. Installed new switch using reverse of above.

I removed the hex head screws from the back of the dryer and removed the back panel, after unplugging the dryer. I tested the various electrical components until I found that the upper limit temp fuse had gone out. Came to partselect.com and found the kit I needed and ordered it. When it came in, I replaced the upper temp limit fuse, and the other parts that came with the kit. I also, since the back was open, used the opportunity to vacuum out the blower fan and as much of the lint as I could get to. Dryer works great now!

Removed the Lint filter, then lifted top panel and rested the panel against the wall.
Disconnected connector attached to the door panel.
removed screws, from both side of door panel and lifted door panel up and out.

Moved Idler pulley to the right taking tension off the drum belt, lift the drum out with the drum belt.
removed old drum felt seal and removed old residual glue, reglued and installed new Rear Drum Felt Seal.
Installed new Idler pulley Assembly and reassembled in reverse order.

Unplugged dryer
Removed back
Removed knob and screw from front and 2 screws from the timer in the back unplugged one wire at a time and replaced one at a time.
Dryer working great.

Used your video, went very easy

Used the maintenance kit....followed the movie tutorial. I also used an empty gallon plastic container to support the front of the drum while stretching the belt over the motor pulley. For the rear drum rollers, before sliding them on the shaft, I put a light grease film on the shaft. After the repair, the dryer runs quieter.

Remove top, front and drum. Top is removed by sliding a putty knife under the front corners and pushing the tabs back. Front is held with screws. Disconnect two electrical connectors. Rollers are easily accessible and changed.

First only replaced the high temp cut off switch which allowed the element to heat. However, after one heat cycle the switch would not reset. Then changed the thermostat (included in the kit). After tapping the cut off switch lightly to manually reset it, the dryer ran perfectly. Moral of the story: always change all parts included with a repair kit!

I simply removed the rear panal of the dryer. Removed the two wires from the fuse at the rear of the dryer. Attached an OEM meter across the two fuse connections and had no continuity. Ordered a new fuse and recieved it in 2.5 days.Replaced the fuse,reconnected the wires and replaced the rear panal. Started dryer and it now blows hot air and runs like new. I can't say enough about PartSelect. Great diagnosis using their website, the delivery was fast and I recieved the correct part at a good price. Very satisfied, Thanks PartSelect. Fred F

My dryer started squeaking and I thought it was the drum rollers, so I bought a set. When I attempted the repair and got as far as removing the dryer drum and I decided to spin the shaft on the motor and that was where the squealing was coming from. I put the rollers on and reassembled the dryer. One day later the motor seized up. Ordered a new motor and installed it with no problems. The nut on the back of the motor ended up being a 20mm wrench. Motor cost me $105.56 and the maintenance kit (ps37308) (2 rollers,4 clips, button clip, new idler pulley and belt) cost $32.08. It cost a total of $137.64 in repairs with no labor costs and I accomplished it in under an hour. Minor handyman skills needed or find a friend who is handy. My dryer is 14 years old and now is running like new again. I used the 50% rule, if a repair exceeds 50% of the cost of a new machine, replace it, if the repair can be done for less than 50% of the cost of a new on, fix it.
