Dryer would spin but no heat
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...)

Replaced a broken pulley.
Half of my pulley was broken off so there were no wrench flats to take it off. I was able to remove it using Channel Locks and the 7/16 wrench shown in the video.

Hint: Use a one gallon ice cream bucket to hold up the drum while connecting the belt. It makes it much easier and gives you more clearance.

Installation went very well. Raised the top of the dryer, removed the front of the dryer, remove the drum, at this point the dryer‘s wide open removed the police and the tensioner also remove your tire rings replace everything back in order as how are you get apart. Repair took about an hour and 15 minutes

Dryer hummed but drum wouldn't turn unless helped.
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.

Lost bearing on dryer motor
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.

The Dryer wouldn't start after pressing the Start Button.
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.

Would not shut off when door opened, interior light would not come on.
Replacing the part was easy: unscrew the old one from the front of the dryer after opening door, disconnect and replace with new one. Getting to it was a bit more difficult: Remove 6 screws from the back, 4 that hold the back of the top down and 2 that hold the control panel in place. You had to remove the control panel to free up the wiring bundle (held in place by a tie wrap inside the control panel housing) so you could move the top forwards enough. Then remove the top of the dryer by lifting the back up slightly and moving it forward to disconnect from attachments in the front and move aside to gain access to the switch.

Both outside door handles turned very beige
Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you
