4KMEDC300BW0 Whirlpool Dryer - Instructions

I did what any novice would have done. I took the entire thing apart to get to the gas jet. I did not know about the thermal fuse until I got to the schematic behind the timer and controls. I was a tech back in the 70's and 80's and only worked on electric dryers. Back then I would remove the heater core and twist the coils together to save money. So I had no idea how a gas dryer heating unit worked. So now any one that reads this. You do not have to take the dryer completely apart, I did that for all of you. Just replace the thermal fuse on the back of the unit by unplugging that wires and removing the screws! It looks like a long white piece of plastic with 2 wires to it. You will find this under the full metal shield on the back of the unit. This should be about a 1 hour repair at the most!

The dryer stopped heating, it would only blow cold air. I removed the back panel and tested the thermal fuse with a dmm. The fuse was open, so it was bad and I needed a new one. I tested the thermostat and the dmm measured continuity across the terminals, so I thought it was good, bad assumption. I ordered a thermal fuse from partsselect and it came with a thermostat. Like a dummy, I only installed the fuse. The 1st time I ran the dryer the fuse blew again, because the thermostat was bad. So, moral of the story, install both parts.

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

Took the top off and then front off and drum out . Replaced Drum roller and shaft support bolts.

Did not have a voltmeter to diagnose so bought several thermostats ,fuses, heating element .Replaced them all and the culprit was one of the the thermostats.Good investment and easy install.

Removed the dryer's back panel and took a look. Had no idea what to do next, so I read up on it. Partselect was extremely helpful to me, the exploded views with the part numbers called out were particularly helpful. So I determined it was the thermal fuse. Unscrewed the screw holding in the fuse and disconnected the electrical supply. New fuse went in really easily. Job took a lot longer than it had to cause since I was in there, I cleaned out the dryer really good.

Why the fuse blew was interesting: had an extension cord routed over the dryer, well it was situated such that it caused the timer knob to bind up. Apparently, the dryer ran all night because of this and blew the fuse. So don't obstruct the knob or you will be replacing a thermal fuse!

YOU NEVER SENT ME THE PARTS!!!
I had to drive to a parts store to find them. On January 17, 2024, I tried to call you when the parts did not arrive and your recording said there were no reps available and you hung up. WE CANNOT GET HELP TO CANCEL THIS ORDER. We have been going in circles with PartSelect and shipping. SO, how do I get my refund of the $107.26 for the parts that I never received!!

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.

very easy

I removed the base cover and cover over my lint blower. The thermal fuse is located on top of the blower housing. I removed the thermal fuse utilizing a small nutdriver and installed the new fuse.

Part came in about 3 days. After reading and checking what was wrong with the Dryer -- which i read if there was no noise coming from the dryer it was the door switch, Looked up the part number and then saw a video that showed how to install the door switch. The video was so informative and precise on everything you had to do and easy Saved money on a service call.

I followed the video. So easy..

Installed thermal cut-off kit. Dryer works fine now. Kit very easy to install.

As seen in video, All Good !

I Picked up the two front corners up, after removing the 2 screws from the vent and the 2 screws that hold the door switch in place, then I disconnected the old switch and put in the new one. Just the opposite of how I took it apart. Very simple and it works great!! Thanks
