4KMEDC300BW0 Whirlpool Dryer - Instructions

Watched Video - very helpful in repair Maytag Dryer working like new now Thanks for your guidance in my repair

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 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!

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

Kill power to dryer from breaker box.Remove lint filter & 2 screws. Take a flat head screw driver and place in gap between rash from corner of top panel & front panel of dryer and pry up to raise top panel of dryer & rest against wall the wall on angle do it doesn’t fall back toward you. Unplug wiring harness from dryer switch inside top front corner of dryer with outside of drum exposed when top panel of dryer is raised. Open dryer door and remove screws on each side of dryer switch located at upper inside corner of door opening. Take flat head screwdriver had slide in between connector & wiring harness on dryer. Remove old switch. Reconnect new dryer switch to wiring harness & remount switch to inside of dryer door opening. Lower top panel of dryer & press front corners of top panel to front panel of dryer & clips will be locked in place. Replace screws in dryer filter mounting holes yo top panel & replace dryer filter in place. Turn on power ‘ & check if light is working 1st. Then, turn timer knob clockwise, close door and listen if the drum is turning. Open door to see if drum turns. If both work, the job is complete.

As seen in video, All Good !

I REMOVED THE OLD TIMER AND INSTALLED THE NEW ONE. ALL I NEEDED WAS A 3/8 SOCKET AND IT TOOK LESS THAN 15 MINUTES. I USUALLY CANNOT FIX ANYTHING AND THIS WAS VERY SIMPLE AND THE VIDEO SHOWED ME EXACTLY WHAT TO DO. THE PART IS WORKING OK SO FAR.

OPENED REAR OF DRYER TOP PANEL, TESTED FOR CONTINUITY ON TIMER, ALL TEMP SENSORS AND HEATER COIL WITH MULTI-MEETER AS DESCRIBED IN ONLINE YOUTUBE VIDEO FOR WHIRLPOOL DRYERS. TIMER TESTED BAD AND REPLACED TIMER. EASY TO UNSCREW AND UNPLUG.

Unplug unit first.
Took the front cover off the front of dryer below the door.

first, I read the other repair stories and used them as a guide.I checked to see if the heating element was broken. It was not. The Thermal Cut off Kit was the ticket for me. I replaced the three easy parts it contained. Repair time was 30 minutes tops that includes checking the heating element and removing and replacing all three possible culprits (of the Thermal Cut-off Kit). Thanks a million. Happy Ending!Oh by the way, my dryer now dries super fast(saving me a bundle)

I watched the video or I would have likley just called a repair man. It took longer to clean behind the dryer than to install the new thermal fuse. After taking the back off the dryer is was as simple as changing a fuse. Dryer works like new for about $20 bucks and we avoided the hasle of getting a repair man, especially since we live in the country. Thanks for having a web site that is so easy to use and full of good information.

unpluged the dryer, took off the back, followed instructions and was able to take of the problem on my own.

I did my repair alone by myself after viewing a short video online at partselect.com The man in the video showed every step slowly and professionally. I took some extra time to clean the dust off behind the back of Dryer while I had it open for fixing.....thanks for your help and it saved me over $190 plus which I was quoted by technician for estimate and parts. I paid $43.00 for my parts...both High limit and Cycling thermostats were replaced. My wife told me good job honey ! You can do it too.

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

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