4KMEDC300BW0 Whirlpool Dryer - Instructions

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

i was able to go on line with your company , find my dryer, order the part and had it the next day. fast , great , service

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

First tried heating element and thermal fuse with no luck. Ordered thermal cutoff and fixed problem. Had I used an ohm meter first I would have determined problem before having ordered heating element and fuse, as both had resistance. I wast just lazy and ordered the took the most common failed components first before taking dryer back off.

Pryed dryer top open and opened front door. . Unscrewed the 2 retaining screws. Pulled old switch from the wiring harness. Put new switch in place and replaced the retaining screws. Put new switch wire plug into the wiring harness. Before closing top, checked door switch function with dryer on. Dryer cut off when door open and when closed dryer started normally. . . Maint. Note instruction book should warn that letting door slam, which I did on occaision, broke the switch arm. Might save future problems.

I ordered all the thermal sensors for the dryer. They arrived two days later and they were the correct parts. It took me about 1/2 hour to replace all three sensors and now the dryer works like new again. My wife was very pleased, so was I.

I basically took the back offo the drive, then detach
the heating coil. Afterwards had to go back in and
change the thermal regulator an the job was completed.

Followed electrical drawing from switch to motor, Thermal fuse was in the line and no power coming through it, removed wire and put together and tested, dryer turned on. Read statements from others at parts select and also bought thermostat because time stopped working last year. Installed both parts and cleaned dryer, works perfect including timer.

It was simple once I figured out what to do:). I removed the 2 screws on the top of the dryer... they were a bit hard to find. Even with the other descriptions on this site. I was removing things I didn't need to. The 2 screws you need to remove are under the LINT COLLECTOR LID. Remove those 2 screws & lift the lid... it will be tight at first. the front of the lid has 2 "catches" in the corners.

The hardest part was getting the door switch assembly to "unplug". We pried it off -- eventually -- & then simply plugged in the new one.

Saved me LOTS of money & was worth the 30 minutes - 1 hour of work.

As I said previously, once you realize how to get the lid up & manage to pry off the plug, that's all there is to it -- easy!

Save yourself time & money & do it yourself!

Grow a second set of hands. Always unplug any appliance. Remove lint screen. remove two screws (philips Head). I took a wooden shim lightly tapped w/hammer to pop front of dryer top free. Mine worked on hinges and just flipped back til it rested against the wall. Removed two 5/16 screws inside holding face on carefully raise face section off the support clips at either side on the bottom. Pull drum out (I have the large style drum commercial size [approx.). Clean the inside free of all lint (known to be fire hazard). Sling new belt around drum. Get newly grown set of hands to hold drum in place. Pinch belt to fit between tensioner, lift tensioner and place belt around motor pulley. Spin drum couple times to make certain belt isn't twisted. Reverse dismantle proccess to put back together. Replace all parts that come with kit, you'll feel better knowing you got a new dryer, almost.

When my dryer suddenly stopped functioning, without any prior signs of pending failure, I guessed that it had to be something simple, like a fuse. I did a google search and stumbled across a forum post that described the symptoms (wouldn't turn on), and the poster said that Whirlpool recommends replacing the thermostat whenever the fuse is replaced. The reason for this is that the likely cause of the fuse burning is that the thermostat is no longer properly regulating the temperature range of the heating element.

I disconnected the power source, and then I removed the back cover, and both parts were in plain view, so I simply replaced the wires one by one.

I spent nearly an hour trying to self-diagnose the problem before I wised up and found PartSelect.com. After reading just a couple of postings I went back and tested the thermal fuse. It was bad. Other posts suggested I replace the thermostat at the same time, so I ordered both. The parts arrived within three days and the actual repair took less than 10 minutes.

unpluged the dryer, removed the back panel, I examined the heating coil, it seemed unbroken, so I used a amp meter to test the various sensors. Found the upper thermal sensor was bad, looked up the part and ordered it, had to get the thermal cut off kit to get the sensor I needed. Installed it no problem, put the back back on, and it worked great.

First, I replaced the heating element which was super easy but I still didn't have heat - frustrating! I then ordered the thermal cut-off kit and thermal fuse. I replaced the thermal fuse and still no heat. Then, I took one of the fuses from the kit and replaced that and finally got heat. There was another fuse in this kit that I still don't know where it goes but right now I don't need it. Had I known (by a volt tester) this would have been super easy to fix, but I didn't have one so it was trial and error. I did find out, however, that if the heating element goes it usually takes the fuse with it. The fuse I replaced (that finally gave me heat) was located in the casing just above the element. I hope this helps!

First unplug your dryer. Then, I removed the two screws on the lint trap leaving the lint trap in place--do not pull out the lint trap--only remove the two screws. Next, slide the top of the dryer slightly forward in order to release the top of the dryer. I did this with my hands. Once the top of the dryer is released, raise the top of the dryer and unplug the door switch assembly. Then, remove the two screws that hold the switch. These two screws were located on the front panel of my dryer and are visible when you open the dryer door. Remove the old switch and install the new switch by putting the two screws you previously took out from the old switch back in place and plug in the new switch. Lower the dryer top. Push the top back to lock in place. Line up the lint trap holes for the two screws that hold it in place and replace those screws. Plug your dryer back in and it should work properly. Very easy repair. We ordered our part one morning before noon, and it was here the next afternoon with regular shipping. GREAT SERVICE.
