Would not heat sometimes
Pulled the big front panel by removing two screws near bottom of front and pulling out at bottom until the top pops loose. Vacuumed out all of the dust and checked for loose connections. Ran dryer - igniter would light, but no gas. Checked the two solenoids with a VOM. the one with the two leads would intermittently read Infinity (open). Super simple repair. Remove two screws on solenoid bracket on top of the gas valve, Replace solenoid and plug it back in with the easy push-on connector. NO PROBLEM - all fixed.

No Heat, no ignition in burner
Our dryer would not heat and it seemed that no gas was coming from the regulator. The igniter was working fine but the burner never turned on. To check the problem, i followed the instructions to remove all body panels until I had access to the burner assembly. I dismantled both gas valve coils and tested each one for open or closed circuit using my multi-tester. I found that the three terminal gas valve coil was an open circuit and was not functioning so I ordered a new one from PartSelect and within just a couple days, had the drier back up and functioning. I also replaced the igniter due to a malfunctioning igniter that has been changed by the manufacture. I must say that PartSelect has the fastest shipping I have ever seen. One part I ordered was at my door in less than 24 hours and I only paid standard shipping...un real! OUTSTANDING....5 STAR SERVICE

Dryer turns off after 1-2 minutes
I tried to follow directions followed by others on this site after diagnosing the problem via suggestions provided by users. I have a Whirlpool Duet dryer from 2002. We've had problems since moving about 3 years ago. I removed the front panel (lower) by unscrewing the two bottom screws (1/4" sheet metal screws). Then I took out the lint screen and the metal tube/contraption immediately beneath to get access to the area where thermistor is located. See the drawing/chart to help you locate this. It's really easier than it seems. Make sure you have the chart/drawing for your model - it makes difference! The thermistor came out pretty easily with a nutdriver that has a swivel offset shaft. Ask your hardware store tool dept. about that one. Put everything back in reverse order of course and test either with/without the front panel re-attached. In my case it fixed at least part of the problem. I was able to get clothes almost dry with most settings but I have yet to install the moisture sensor to see if that helps in addition to the internal-bias thermistor. I am the kind of person that does one thing at a time so at least I now know the thermistor was bad. Good luck and hang in there with your own repair. It's a lot cheaper even if it takes you longer to do than a pro.

The Dryer Would Not Turn On
The dryer wouldn’t turn on at all. It was like it was unplugged from the wall. However, fixing it couldn't be easier. I simply removed the back panel, found the fuse, tested it with an Ohmmeter (to determine that this was the part that didn't work), ordered the part from this website, and replaced the part. The part arrived in about two days. The shipping was a little pricey, but overall the whole thing cost me $20 vs. whatever it would cost me to get someone else to repair it. The website helps to identify the problem, and it is helpful to read how other people fixed their problems. It was so easy and the service was so good, I will definitely use this website again and recommend it to others.

Replaced two parts in the gas heater assembly
I removed the front panel of the dryer by removing the 2 screw that secure it at the bottom and pulling upward to disconnect the cover at the top. I then removed the two screws that hold the metal cover that secures the 2 elements in place. I disconnected the wire plugs from the 2 elements, removed the 2 elements and replaced them with the new parts making sure to place them in the same positions as before. I then replaced the housing cover and tightened the screws. Then I replaced the front cover of the dryer.

dryer worked but no heat
Initially we thought the problem was the igniter, so we ordered an igniter kit. Installed it but was unsuccessful. We then went on the websight and read further, about 50% of dryers with no heat but working had a problem with the thermal fuse.So we ordered the thermal fuse installed it, which was very easy, and success. Once the problem was diagnosed properly it was fast and easy. Recommend looking at the statistics for specific problem.

Heat Would Not Come On
After replacing all the other fuses and sensors I finally replaced the Radiant Flame Sensor and it is working perfectly.

After replacing the other parts and the heat still not coming on I read somewhere that the Radiant Flame Sensor is a normal closed circuit and when I checked with a meter it was open. I would have saved a lot of time and money if I had read that earlier.

noisy drum
the job would have gone faster if the right parts had been sent in the first place. I would have never paid for two day shipping. In the repair, I removed the rear panel, clipped the plastic triangle holding the bearing, installed the new bearing and new clip.

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!

Squeaky Dryer
I looked for squeaky dryer within parts select and went with the 80%. I received the Maintenance Kit, replaced two rollers and it works like new. Amazing since this is the first time I have ever opened a dryer. The instruction sheet and parts were all I needed.

Door would come open while drying clothes
Very bad design to keep door shut but very simple to fix. Just screw bad strike out and screw new one end. Whirlpool should have gave extra when you buy this type dryer.

Dead motor
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...

Door latch wouldn't latch
Like another reviewer's repair story, I decided to take the door apart. It was too difficult, at least for me, to get the faulty catch out without damaging either the the door or my hands. This is why I give it an "easy" rather than "very easy" rating and put the total repair time at a half hour or better. I also decided I wanted a second person to help - not with getting the door apart or putting it back together, but because a second pair arms was very helpful in rehanging the door well. We removed the door (four screws), marking which side of the hinge needed to be flush with the actual dryer when rehanging. Then we took the door apart, which comprises another sixteen screws (four on each edge). We used an electric drill but I'm sure it could be done manually. We used needle nosed pliers to get the faulty latch out of that side of the door, then replaced it with the "back up" from the other side. Then we put the door back together and carefully rehung it. Done. We did decide that, in future, all kids (we have three boys) slamming the door would be severely beaten. Pushing the door until it's against the dryer, then PUSHING (as opposed to slamming) the latch ONTO the catch pin on the dryer is obviously what was intended. However, I've learned not to count on my boys being particularly conscientious, so I'd ordered four replacement latches to keep on hand. This machine was delivered in April 2009 and I replaced the latch in April 2011. Based on this and our laundering habits, I'm sure the others will be used long before the dryer calls it quits.
