Dryer quit heating

I removed the hex head screws from the back of the dryer and removed the back panel, after unplugging the dryer. I tested the various electrical components until I found that the upper limit temp fuse had gone out. Came to partselect.com and found the kit I needed and ordered it. When it came in, I replaced the upper temp limit fuse, and the other parts that came with the kit. I also, since the back was open, used the opportunity to vacuum out the blower fan and as much of the lint as I could get to. Dryer works great now!

Dryer would tumble but not heat.

Used an inexpensive multi-meter to detect that there was no continuity through thermal cut-off (high end) or disposable thermal fuse. I identified these parts by reading your online schematic of the dryer. I noted that the flexible ducting had been crushed on the dryer which lead to the feasibility that the thermal cut offs, especially the thermal fuse could have burnt out. Ordered the parts on Monday, drying clothes again on Wednesday.

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.

Dryer would't heat up and noticed a smell of something very hot just prior to dryer not heating up.

Prior to ordering parts i moved the dryer out and took the back off the dryer with a nutdriver. I noticed right a way the heating element was damaged and burnt up. I ordered the above parts and recieved them in two to three days. the parts on my dryer were easy to get to and I just matched up the parts i recieved and replaced them one at a time. It only took a nit driver to remove them and plug the wires back in to the new parts.
the dryer works like new again.

No heat

The dryer stopped heating, it would only blow cold air. I removed the back panel and tested the thermal fuse with a DMM. The fuse was open, so it was bad and I needed a new one. I tested the thermostat and the DMM measured continuity across the terminals, so I thought it was good, bad assumption. I ordered a thermal fuse from PartsSelect and it came with a thermostat. Like a dummy, I only installed the fuse. The 1st time I ran the dryer the fuse blew again, because the thermostat was bad. So, moral of the story, install both parts.

No heat

Purchased new heating element and replaced. This was the number one recommendation for the fix for my problem. I do not have any measurement devices to check any of the parts. This was trial and elimination. The old element was badly burnt. Still no heat. The second recomendation was the thermal fuse. I purchased that and replaced. Still no heat. After reading through some of the repair forums on this site I decided to try one more time and replace the thermal cut off kit. A little harder to do because it required cutting and replacing some wire ends. That was the problem. We now have heat and once again I have a happy wife! I left the new element and the fuse in. The dryer heats much faster than it did.
The repair videos on this site were very helpful. Some of the wire changes on the Thermal Cut-off Kit can be very confusing.

Dryer blew air but no heat

Our dryer quit heating and I feared that I would have to buy another one as I have never worked on a dryer. But figured I would go online and see what I could learn. Parts Select gave me the info that I needed.
Not being sure which part was bad I decided to start with the one time use Thermal fuse. When I noticed that it only cost 7 bucks and my wife had been complaining that the dryer had not been heating well for a while I figured I would go ahead and replace themostat. I ordered the thermal cut-off kit and replaced both parts. I put them on and plugged it back up and it is heating fine. I found the videos very helpful in showing how to do this.

No heat

To be short and sweet, the repair was simple once I got the parts I ordered which came really quick. I put them on and it worked fine. Ez to install as well. It only takes half the time to dry, it seems to work better than when it was new. I saved hundreds. The repair man was going to charge $69.99 just to come out to see what the problem was. The parts I needed were under $100 so figured I'd try an do it myself, after reading others repair stories. I did it! I will be a repeat customers if something else breaks down. Thanks Partselect.

The ice guide for our fridge was broken. No heat for the dryer.

The ice guide snapped right in 2 minute job.
With the dryer I had to remove the back of the dryer which was about 8 screws another 5 screws for the One time use thermal fuse, the thermal cut-off kit and the high limit thermostat. I used a nut driver and it took about 20 minutes. I am not sure which part needed to be replaced but seeing that I had bought all 3, I replaced all three.
The dryer works fine now.

CustomerTimothy from Anderson IN

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...)

CustomerStephen from Wilson NY

Poor dryer performance and slow drying!

I knew that the dryer needed a new belt and since the dryer was also failing to dry the clothes in one cycle, I decided to replace the three thermostats, figuring that I might as well do all three if I'm going to open up the dryer. I downloaded a schematic of the dryer from the Whirlpool web site, which helped me to order the right parts and see how I would be able to make the repairs. Once I figured out how to get to the drum for the belt replacement, installation was quite easy.

First step was to unplug the dryer, remove the vent hose and remove the back panel with a nut driver. Once the back panel was removed, it was easy to see all three sensors. The heating element unit was easy to remove - two screws. This made it easier to replace the sensor. Each sensor was shaped differently, making it easier to decide what went where. This normally would not have been a problem, but the part numbers have changed for this dryer. I could have also cross referenced the parts by using the partselect.com web site.

To access the dryer drum, I had to remove two screws on the back of the dryer that are located in two tabs that hold the control panel to the dryer cabinet. Once removed, it was easy to lift the top of the cabinet and swing it up and against a nearby wall for support while I replaced the belt.
I removed the old belt from the motor pulley, and then just removed the whole drum. I placed the new belt around the drum, placed the drum back in position. With my wife supporting the drum, it was easy to bring the belt through a guide and slip over the motor pulley. Then, I rotated the drum manually to make sure the belt wasn't twisted.

After ten minutes of putting everything back together, it was time to plug in the dryer and test it. I did it without a load first and checked the vent for hot air. After that, we did a couple of loads...one on high and one on perma press, and when the cycle was over, the clothes were dry!

Delivery time from PartSelect was super fast! Prices are excellent, and I really appreciate such a helpful web site. Anyone with a small amount of mechanical ability and "do it yourself" experience can save $$$ by fixing it yourself. Having someone service this dryer would have cost me more just to replace the belt.....let alone the added insurance of replacing the sensors. And, I learned that if the heating element should fail, replacing it would be a snap, and would start with a visit toe partselect.com!
