I used a screwdriver to remove the old part and pushed the new part in with my fingers, it was very easy. If I could do it, anyone can. I was a lot cheaper then having a repair man come to house. I am very glad I found your site online, I will definitely be using your company again.

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 watched the video on how to diagnose problem and then how to repair . Videos were very helpful. Also the parts were ordered on line and arrived in 2 days. Parts at a local appliance parts store were twice the cost of what I paid for the parts from PartSelect.

How to un-screw the blower fan!

The dryer motor quit working. Learned, if you are changing one that is old, get the blower wheel fan too! I could not break mine loose from the motor shaft, and had to bust it off.

To un-screw the blower wheel fan from the motor shaft: from the front of the dryer, grab the plastic fan on the back of the motor with an adjustable wrench, and the motor shaft on the front of the motor with vice grips. Turn the motor shaft CLOCKWISE holding the fan still to un-screw the fan. If you have to remove the pulley, grab the shaft and turn the pulley COUNTERCLOCKWISE with a wrench.

Just make sure to pay attention to the orientation of the new motor in the instructions. If you match the old motor, it will not fit. It is all spelled out in the directions.

And on You Tube up came several videos showing me how to ewmove the switch and install the new one.

The hardest part of the job was not instaling the switch but the dryer Vent hose from the back of the dryer after I puled it away from the wall, it disconnected and the I had to Pull the Washer out which was right next to it so I could put the vent hose back to the dyer.

I ordered the timer at 11pm on Thursday and had it in my hand Saturday morning at 11am. 36 hrs delivery time is FANTASTIC as I only asked for standard 3-5 business day delivery.

Exchanged the wires from the old timer to the new timer and had everything up and running in minutes.

Thanks partselect...To think I used to pay a guy $70 per hour to do this kind of service.
AND
My 16 year old can now fix a dryer...!!!

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.

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...)

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.
