Dryer would not start

My wife was doing a load of laundry when she thought the the dry cycle was finished she found the cloths still wet. When she went to restart the dryer nothing. I did some research online and found the most common problem was the thermal fuse. I removed the back of the dryer removed the fuse and checked for continuity with my volt meter. I thought that I was going to find alot of lint build up. However I did not so I decieded to also replace the thermostat, using the thermo cut-off kit because this might have caused the fuse to fail. I ordered the parts from partselect and they arrived in two days. Partselect has excellent instructional videos on how to make the repair. It was quick and easy and saved the money of just going out and buying a new appliance.

**** Remove power cord from the wall****

As said earlier, you will need to lift the top. Drop the two screws holding the lint shoot and pop the top by sliding a screw driver into the corner on the front. Lif tthe top and rest against the wall behid the unit. remove the two (4 total) screws at the top and bottom of the front door assembly.
Place sometin under the front portion of the drum. At this point you'll see the need to clean everything! :) Slide the belt off and around the drum, (take note of the routing it takes.) Remove the drum by gently pulling it towards you. Set it aside. Clean more. :) (It is nice to have a vacuum handy.) At this point you really need to get to the rear of the system. So I tipped the top back down, and spun it around. Removed the rear panel and cleaned some more. (15 years of a lot of lint in there!) Then you'll need to remove the rear cover on the left side, covering the blower impeller. Get read for a whole lot of debris. Vacuum again. So now you have the motor exposed in the front and rear. You need to remove the impeller by turning that clockwise to loosen it. The trick is holding the shaft in place from the front at the same time. I used an old rag and wedged it into the impeller edges and worked it around until it jamed up. Once the rag was wedged pretty good, I went back to the front spun the shaft. Then you can remove the impeller by hand. Vacuum more. You may get by without having to remove the lint shoot completely, but I did just to clean it up more. I did have to remove two screws in the upper corner near the top of the lint shoot. (Basically the hold the back in place.) I took a few notes at this point about the wiring harness. Used a heavier screw driver (standard), You can push down on the clips that hold the old motor in place. Then work it out the front. Clean more. The new motor is not an exact replacement slightly differnt but the instructions with it were ok. Follow them for the correct wiring. You will need to remove one wire and cut and recrimp a spade lug or two. I used ty-wraps to secure the lines back in place. Look closely at the diagrams and make sure you set the motor down in the same direction the instructions say, if you twist it slightly it will sorta lock in place where it needs to be. Re-install the hold down clips to the front and rear of the motor. Clean up your impeller, and reinstall it too. Then basically reassemble the dryer...tracing your steps backwards. This isn't really difficult, it just takes time and as you can see, you will/should clean as you go !

No heat in dryer

Once I unpluged the dryer and then removed the back cover, I located the heating unit and then removed the thermostat. Once that was done, I installed the new thermostat and connected the wires. I tested the dryer to make sure that it would heat. Then I replaced the back cover.

Drum spinning but no heat

  • Customer: Chad from Derby KS
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Socket set

Purchased thermal cut off kit but only replaced the top most thermostat. There were some extra wires wired into the bottom thermostat, that were not described on the video or any other repair user posts. It checked fine on my multimeter anyway.

Dead motor

  • Customer: Robert from Glencoe IL
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers, Socket set

1. Shut off gas and disconnected dryer.
2. Opened cabinet. Easy sheet metal screws and fairly obvious how everything goes together. NB: You'll need a block (or a helper to hold things while you run to look for one) to hold the drum while removing the front.
3. The motor is connected with a single harness, so wiring is a snap.
4. Removing the blower wheel from the back was hard. I braced the motor shaft and turned with all the leverage I could muster, but it was stuck. Plan B: Recip saw to cut the shaft. Motor comes out one side and the fan comes out the other.
5. The fan, of course, was unusable because there was still a piece of motor shaft stuck in the thread. This is why I had to spring for a new wheel.
6. Put everything back together and receive wife's adoring praise...

dryer would not turn off when the door is open

it took loess than 10 minutes to change the door switch after watching the repair video

Dryer would not tumble.

  • Difficulty: Really easy

I wasn't sure if the problem was the belt (probable) or the idler pulley assembly (less likely) but the total for both parts was about $26 plus shipping. So why not replace both to be sure?

As it turns out, my original idler pulley assembly does not turn. Rather, it has a concave semi-circular piece that is fixed in place. The belt ran in a groove in that piece.

The replacement part has a nylon wheel that turns. As a result of replacing the idler pulley assembly (which I don't think was necessary to fix my tumbling problem) the dryer runs much quieter. (We used to get a fair amount of squeaking when the belt rubbed).

As for the actual repair (I would rate myself as above average on tackling household repairs), it was about the simplest repair I've ever done. I followed the video provided on this site (excellent video) and it took less than 20 minutes -- cleaning up all of the lint/odds and ends under the washer and dryer took longer than the actual repair.

My only issue (minor) was disconnecting the electric harness. It did not slide as easily as in the video. I had to coax mine a bit with a small screwdriver (make sure your dryer is unplugged!!). I suspect it was simply a function of the harness never being unplugged -- the dryer is 9 years old.

I also felt great because I'm sure I saved a $125 service call (for only $26 in parts and 20 minutes of my life).

Good luck!

I disassembled the dryer once to clean the motor and compartment. After reasembly, the problem persistes. I ordered the motor and the second diasasssembly was accomplished in 10 minutes and the entire job took 45 minutes and the dryer was running like new. Tip- Leave the motor secured while removing the blower fan.

Badly worn idler pulley and rollers.

Braced dryer drum with a block. Removed the two rollers one at a time by using a screwdriver to pop off the triangular clip. Slid on new rollers. Would have been easier to remove the drum out the front instead of bracing it. Installed new idler pulley and belt. Dryer is 25 years old and sounds like a new one now when running.

dryer sounded like I was strangling a dog

First, I watched a utube video of replacing the dryer belt. Then I went to Sears Hardware and couldn't find a part. Then I ordered the parts for my favorite online repair parts source - partselect.com. I had the part in one day! We did exactly what the video showed and also replaced the two wheels that looked like roller blade wheels. Piece of cake. Saved a $75 repair call plus whatever the parts would have been and spent about 20 minutes doing it. Back in business. Great for a 12 year old dryer! Buy the dryer kit!

dryer would stall and the motor would hum before tripping circuit breaker

When the problem first came up, I took the dryer apart without first looking up any instructions. This wasn't difficult, but didn't realize when removing the fan from the motor, there is a square lug as part of the fan hidden by the rear clamp securing the motor. I was able to remove the fan by holding the motor shaft with a crescent wrench and removing the fan by hand, but was difficult and gloves were necessary in case the fan loosened quickly and my hand came in contact with the sheet metal (very sharp).

I took the motor out and attempted to clean it as it was loaded with dust as was the dryer internals. I tried to lube the motor bearings and appeared to free up, but the sight of metal shavings on the rear bearing seal had me concerned. This ultimely did not work and was trying to buy some time until the new motor arrived.

This is when I looked up the motor part number and found that Parts Select had the part number in stock. I ordered the motor on a Saturday afternoon and got a quick response acknowledging my order. The motor shipped that following Monday from Fresno and arrived on my Southern California doorstep Tuesday. These guys have their act together and are helpful in making the repairs. In my case I did not have to make any adjustments to the wiring or the pulley for my model and replaced the motor the following weekend in about 45 minutes. Since I had the unit apart several times before replacing the motor, the installation went quickly.

The dryer is again working fine for a unit 12 years old and my wife is once again happy that we didn't have to purchase a new dryer.

I has to disconnect the Hot/cold water line pull the washer out connect the dyer hose reconnect the cold /hot water lines and yada yada yada

PartSelect sent me three different door catches with instructions for choosing the correct one. I did choose and simply inserted it into the slot and voile! All finished and it works great now! PartSelect had the part delivered the day after my order was placed. I would suggest doing business with them to anyone asking who they might contact for a part. I especially appreciated the ease of identifying and ordering from them. I was able to do all of this on-line via their website.
