Dryer would not heat....at all.

Not noticing the break in the heat coil, I ordered two other minor parts, before ordering the heat coil. Less than 10 minutes to replace the old one, and now it works great! Thank you for your installation instructions and parts diagrams!

The drum would turn but no heat o rtimer

I followed the diagnosis sequence found on your website. The detailed diagrams of the unit helped. I tried to use the factory website but it assumed the reader had a certain amount of practical repair experience. The parts were delivered very quickly. I would have liked to have known if there was some way to test with a meter some of the original components I eventually had to purchase so I could narrow the problem down more closely.

No heat in dryer and lint filter torn

Dryer didn't heat. I got the heating element thru sears and when I ordered it I thought I should also order the thermostats but I didn't. Element arrived two days after ordered right on time. Slipped right in in a few minutes. Turned dryer on. No heat. Went back to drawing board. Watched videos on part select site and realized I needed thermostats. Ordered them and lint filter. Arrived right on schedule and also slipped in in no time flat. Turned dryer on and yes it heated perfectly. Wife was pretty impressed with new lint filter as other one was torn with jagged edges. MY SUGGESTION: if your dryer doesn't heat and you can't test each individual item thermostats and heating element order the three of them ( high limit and cycling thermostats and heating element) cause they'll probably will all go at the same time anyway. Then won't have to wait on the second shipment if things don't work with partial replacement. Parts select was great and videos are well understood and easy to follow. Would certainly use again.

Dryer was only intermittently heating, very poor circulation so clothes weren't drying

I tested the continuity of all of the fuses with an ohm meter. It was very easy to replace the thermal fuse and cycling thermostat (less than 15 minutes). A possible cause of the problem and symptoms was also a large buildup of lint in the lint chute/blower housing area which impeded airflow severely. It was easy to unscrew it and pull the lint out. It works like new now.

Dryer wouldnt turn on.

Followed the instructions in the video provided on the partselect website. The video's instructions were excellent. Simple removed the back comver of the dryer, located the parts and replaced them. It would have cost me at least $500 for a new dryer. At least $150 to have a repair man come. I did this repair myself for $45!! I highly recommend partselect.com.

CustomerDebby from Charlottesville VA

No heat. Spinning and blowing fine.

Extremely easy! I used this website's part diagrams and videos to find out where the parts were in the dryer. I only needed a 1/4" socket on a screwdriver handle to remove the back of the dryer and the same socket for the screws holding most of the parts on (one needed a phillips screwdriver). I didnt have a ohm tester, so I ordered the heating element, cycling thermostat, thermal fuse and 250f Thermostat, knowing I could return the one(s) I didnt need. Replaced them all and guess what...it still didnt work! So I read some other people's comments and found out there was one more part I hadnt ordered that might be the problem...the THERMAL CUT OFF KIT. It has the 250F thermostat PLUS another (different) Thermal cut off fuse, that attaches several inches above the heating element. I ordered that part, got it the next day, and the Thermal cut off fuse that was in the kit (not available separately) ended up being the solution to my problem! The wire to it was actually fried, so the extra connectors in the kit were perfect, and I just cut and stripped the wire a little and put on the new connector, and the dryer works great.

Dryer not drying/no heat

The diagnostic tool on the web site was great, offering the top reasons for my problem. The web site schematic diagram of my dryer was extremely helpful for the repair. Taking the back panel off and having the schematic for guidance made it possible to replace the parts in about 20 minutes. ALSO, I ordered the parts on-line on a Thursday, and the parts were on my doorstep the next day!! Awesome service which I have passed along the info to several friends.

CustomerFirmin from Lansing MI

No heat problem

First off I was really impressed about the videos provided. They helped make the repairs with more confidence. I changed just about every part related to an heating problem before I hit the defective part. Part I changed were Heating Element - 5600W 240V, Cycling Thermostat, Thermal Fuse, High Limit Thermostat. After replacing all these parts, still no heat. I then read that the Thermal cutoff kit has an additional sensor that you can't get separately but as a part of a kit which forces me to purchase an item twice. After another week spent waiting for the second order to arrive, the part came and I was able to replace and regained heat fairly quickly. Yeah! I do have an ohm meter but the dryer is at a location that is very difficult to reach when plugged in so changing the parts one by one was the safest way to go. It is fixed now and we are all happy. My only complaint is that the thermal kit was not mentioned as a possible issue or else I would have ordered it on the same order. In any case this earned me major brownie point to my significant other double Yeah!!!

Dryer runs not much heat..

I am almost 60yr. old, I have never come across a better do it yourself site ever. The repairs went well and the video instruction were even better, where have you been my whole life? Instead of picking & plucking parts I went for all 3. I have gone back and forth to stores way to many times in the past for repairs. This was quick and easy and I had no doubts about the job. Prices were right shipping was fast and my wife & I are now happy dry people. Thanks much PARTSELECT

CustomerAndrew from Alturas CA

No heat

I first repaired the most likely suspects. The heating element and fuse. That did not do the trick. So then I replaced everything else that could effect the heat, that was over 1% of the likely problem. Wala...fixed. Directions were easy, work was easy and the result was a working dryer, good as new. I probably replaced a few items that were not bad but the entire cost was just over $100. A far cry from replacing the dryer at $599

The burner would fire off when you first started drying cycle but would not fire anymore after that

I REPLACED THE CYCLING THERMOSTAT BUT THIS DID NOT REMEDY THE PROBLEM AND AFTER FURTHER EVALUATION I DETERMINED THAT THE SECONDARY SOLENOID COIL (HOLD/ASSIST)HAD AN OPEN COIL WIRE ON THE GAS VALVE. THIS IS BEST PURCHASED AS A SET, PRIMARY COIL AND SECONDARY COIL, AS IT IS LESS EXPENSIVE THIS WAY.
