YHED4300TQ0 Magic Chef Dryer - Instructions

First, I unplugged the dyer and then I removed all of the screws for the panel that covers the rear of the dryer. This exposed the cycling thermostat's location. I then removed the wires, one at a time so I would be able to put them back on in the same place. Then I removed the one screw using a nut driver and then put the new cycling thermostat in place. It was pretty easy.

This was so much easier than I though it was going to be. Pulled up on the top part of the dryer and folded it over to the back. Removed 2 screws for the front panel and disconnected some wires. Laying down I fed the new belt on and made sure the tensioner was put back into the right spot, because when the belt broke the tensioner sprung to the other end of its travel. Put everything back together. This was made super easy because you guys had the parts and the shipping was super fast. Alot of the local shops in the area didnt even carry the belt or were not helpful..

Just follow the instructions the one was provided with Maitanace kit we bought from you.

First I unplugged the dryer from 240V and removed the back cover upper (behind the switch) and lower (exposing the remainder of the parts)

Inside the upper section was a folded wiring diagram of the dryer (don't know if this was courtesy of Whirlpool or another individual, but it was a very nice touch.)

I did a resistance measurement across the heating coil and found out it was fine. I then plugged the dryer back in and carefully took voltage measurements from one phase of power (this was easily accessed where the power comes in to the dryer, just be careful not to touch or short the wires)

I had an assistant turn on the dryer (this makes things go a little faster, as you are behind the dryer otherwise) and checked for 240V across the heater coil.

Once I did not have this, I kept one lead on the left side wire (one of the power phases coming into the dryer) and moved the other lead to the left (as viewed on the wiring diagram) until I no longer had 240V. This identified the faulty component as the Thermostat High-Limit, non resetable.

I ordered the kit with the High Limit NR and High limit Thermostat (as both had to be bad). I also ordered the 150 degree cycling thermostat (although this was not necessary - for <$20 I opted to replace it as well)

Removing wires one at a time, each component is fairly easy to replace.

My only complaint is that with the combo kit, the wire attachment is a little different that the original component and requires you to cut an existing wire and crimp a different terminal to allow all three wires on the High Limit thermostat (250 degrees) to be attached. There is little to show you how exactly the crimp is to be connected (it goes on the smaller of the three wires - DO NOT CUT the jumper provided and USE A GOOD CRIMPER - not the $2 variety, or you'll be getting a new connector!!) The connector provided is designed for some strain relief from one connector to the other, however) An additional jumper with the appropriate connectors already attached would be a nicer design.

Also, make sure you do NOT screw in the smaller cover that covers the power in until you place the entire lower half cover back on the dryer (unless you want to take it off a second time, as I did...) as it uses a common screw to hold both in place.

Overall, fairly easy to do with a minimum of tools, straight blade screwdriver to remove stubborn wire connectors (esp. for HT thermostat 250), ratchet and socket for quick removal and replacement of covers, and a good T&B style crimper ($10-$20 at your local hardware and well worth it even if you only use it a couple of times)

30 minutes and done - the dryer now cranks out the heat and the advanced settings (Auto dry) work great - no more 2-3 times throug to get things dry.

If you have a minimum of mechanical ability and a little bit of electronic troubleshooting skill, you can check and repair this youself and save about an $80-$100 service call.

Thanks to Part Select for the diagram of the dryer layout as well!! (Schematic would be nice if available online, though!)

Shipped the part in about 2 days from order time, as well. Will be back (hopefully not soon, though, as something has to break first!!!)

Be safe and good luck!

(One last note: Make sure your lint trap is clear including the hose - either due to build up or a lazy kid...as this probably caused the failure as heat could not escape...)

I installed a new timer switch...loosening the six wires was delicate...I used a synthethic lubricant to loosen them first...that helped. Also, the wires are a different color so I made a diagram to make sure I got the new ones in place correctly...this was for an out-of-town rental so I left the dryer disabled for about a week while my renter was on vacation. All went well...the photos on your web site helped a lot to make sure I ordered the right one. Thanks!

I found a video tutorial that explained the three things that are usually the problem when a dryer stops working. This showed how simple the task is. I used a multimeter to check the switch, to make certain that this was the part that needed replacement. This was part of the tutorial, as well. I ordered from PartSelect because it was recommended to me by an application that I use to find places where items are less expensive. The correct part arrived in a few days and it worked fine. I'm not a handyman by any means, but the tutorial showed exactly what needed to be done. It appeared simple and it was.

Old door catch came out, new one slipped in. All works great.

Looking at the schematics, it wasn't clear exactly where the motor was located. I took off the rear panel thinking I could get to the motor through the blower. Realizing that was a no-go, I did some web searching and found that the lint screen chute had to be unscrewed, the top had to be lifted to gain access to the top 2 screws holding the front panel to to the main body. The barrel was then dropped and the rib belt removed from around it so I could set it aside. The clips were removed from the front and the back of the motor to gain access to the blower shaft. .The motor shaft is screwed into the blower shaft but it took me a while to figure out how to grab the blower shaft( made of hardened plastic?) with an adjustable wrench while torquing the end of the shaft with a (3/4"?) socket wrench. Access to the rear was rough, but getting the motor out an back in was easy. The spring tensioner for the belt was the next hurdle. With the s-curve facing outward and clipped to the base, the belt with the rib side wrapped around the barrel, the belt was slid between the roller and the tensioner bracket and wrapped around the motor drive rib side inward. I had to take the old motor to kind of prop up the barrel so I could at least see the tensioner and motor interface. I had to do a balance trick where I held the barrel up while centering it to the belt and the rear panel while ensuring the cloth seal was seated to the outside of the chamber. The front panel went on, and the front cloth seal was seated by spinning the barrel. The rest was just a matter of reversing the steps. Tons of lint/dust is probably what crashed this motor. Disassembling the front and the back allowed a thorough clean up - vacuuming and wipe down. Should go another 10 years/

Numbet one - unplugged the dryer. Then disassembled dryer (front panel, loosened vent from top panel and removed drum). Removed motor after carefully documenting wires and their corresponding numbers, along with pictures. Read directions several times to assure we understood process. Followed instructions for replacing connectors. Used pliers and screwdriver to install motor clips. This took numerous, patient attempts. We also had to partially remove the vent in order to reinstall the motor. Then replaced drum, front cover, reattached vent to top cover. Reattached outside vent hose. Plugged dryer in and tested it. Motor replacement worked fine and fixed the problem (squealing).

First I pulled out lint catcher, you will see two screws ,removed two the screws on top ,( philips head screw driver) I than took a putty knife and pushed in the front of the dryer under the lid and lifted the top up, I than removed a self tapping screw on each side with a 5/16 wrench and lifted the front panel out. I than pulled out the drum and this exposed the two rollers, I than pulled of the nut locks with athe pliers , took off the plastic triangle snaps and pullled off the old rollers , replaceing them with the new ones,put the triangle locks on and that the lock nuts on , I than put the drum back in, than the front panel, replaceing the two self tapping screws , snapped down the top,replaced the other two screws again on top and replaced the lint catcher, I was done.

UNPLUG THE DRYER!!!!!
First removed the two screws holding the lint filter in place. Then slipped a screw driver between the top and the dryer body to remove the top. Using a nut driver removed the two screws holding the front of the dryer in place, remove the two wires for the door switch., lift the front cover of the dryer and set it aside. Support the drum ( two extra hands would be nice) and remove the drive belt. Then remove the drum. A thorough cleaning to remove all of the scorch like stain from the drum and back plate. Remove the seal and glue the new one in its place. Put it back like you found it. Make sure that the seal is not tucked against the back plate. Dryer works better than new and no more stains.

Watch the utube video a few times. Followed instructions. Marked all screws. Cleaned the inside of dryer where motor is. Replaced drum seal and then belt. I replaced front of dryer screwed everything in place and I did it. Holding drum in place while installing front of dryer was hard as it was heavy but I did it m. My friends and husband couldn’t believe it. Utube is great!

Solution: electric motor replacement as the integral centrifugal switch lever (plastic cam) wears over time causing the start windings' switch poor contact. Took it all apart, (back panel, front and top) including lifting the drum out to completely expose the motor. Needed to wrench the plastic fan from the inside motor shaft. Tricky part was swapping the original pulley (6 rib belt, still good) for the one supplied for 4 rib belts. I needed to file another flat onto the other side of both motor shafts (old and new) to break them free, using a vice to secure the pulleys. The dryer works perfectly! It's a great dryer that can be repaired by a determined novice. The enclosed instructions were helpful, although if followed about cutting the original motor shaft to obtain its pulley might require drilling the shaft from the pulley = nonsense. Thanks again Parts Select.

I looked at the parts breakdown to see how it cam apart.

I tore the dryer down,
1. removed the door
2. openned the top
3. removed front panel
4. removed fron bulkhead
5. removed belt and drum
6. removed back cover
7. removed the ductwork
8. removed the fan (this is the hardest part, it is very tight on the motor with left hand threads, there are flats on the (inside of the dryer)fan where the motor shaft goes into the fan for a wrench and you can put a socket on the front pulley on the motor. I ended up just knocking the center out of the fan and replacing it.
9. removed the motor and cleaned the entire unit
10. reinstalled everything in reverse order. Note:I went ahead and replaced the idler pulley and the rear wheels that support the drum, and put a new belt in (just about
everything that could fail) I spent about $200 to keep a $1200 dryer in service at least another 7 years.

Troubleshhot problem, used multimeter to verify current to motor. Once that i was sure motor was getting proper voltage, I used a meg-ohm meter on A/C motor windings and physically tried to turn motor and found that it was siezed. I then cleaned inside of unit inspected belt and drum rollors. Due to the cost of the items, I decided If I was going to replace the motor I should replace all moving parts, and install new belt. Everything went easy. WHAT WAS MOST IMPRESSIVE! was that the Parts people sent the correct parts on time the first time, with no hiddin charges. There web site should accurate diagrams of parts and internals of machine. I was really pleased and will use this service again. Thank you
