I’m not sure how often this happens because it hasn’t happened to me or anyone I know before. But our dryer seems to be getting too hot during cycles. The clothes are way too hot when they come out, even on the lower settings. The heater element is still cycling on and off though which is think is normal. I’ve already checked the flow and the vents and everything seems to be square there. What would you recommend I check next. Do you think it’s the thermostat?
Hi Kealan, we recommend trying to dry a load with the vent unhooked from your dryer. If you are still experiencing these symptoms you could have a faulty dryer cycling thermostat WP3387134. I hope this helps!

Is there a way to test the thermal interna bias switch to be sure it is the problem
For model number Ler7646ez2
Hello Jerry, thank you for contacting us. With a multimeter you can test the two large terminals on the thermostat, they should read closed for continuity and the two small ones should show an ohms resistance value. We hope this helps and good luck with the repair!

My dryer is taking too long to dry the clothes in it and I am not over filling it. My friend suggested a blockage but we already checked for that. We also tried using the different settings and the only one that seems to be buggy and not working is the highest setting. So do you have any suggestions of parts to check or tests to try to fix this.
Hi Dylan, we recommend testing the temperature coming from the dryer when on high heat, which should be about 110 (low end) to 160 (high end) degrees. If your dryer is cycling before it hits the 150 degrees, you most likely have a faulty cycling thermostat. This can be tested with a multi-meter with temperature. Best of luck with this repair!

Greetings, i recently replaced the thermal fuse, cleared the venting ducts, etc. The dryer started up right away, i thought all was well. However, the next day my daughter informed me that her dryer had stopped working again after drying a tablecloth for approximately 20 minutes. I suspect the thermostat is not cycling properly and is causing the dryer too overheat and blow the thermal fuse. Wondering if i should replace the thermostat and the thermal fuse(again). Thank you very much.
For model number IED4400VQ1
Hello Steve, thank you for your question. I would recommend changing the fuse, as well as the Thermostat, Internal-Bias WP3387134. This thermostat is in tune with the temperature of your dryer and regulates it in order to maintain a certain temperature. This thermostat reaches a temperature of 155 degrees, turns off, and then turns on again once it has dropped by 25 degrees. If the thermostat isn't turning off, the unit will overheat and the fuse will blow. I hope this helps!

My dryer is not heating. Trouble shooting leads me to the internal-bias thermostat. Testing with an ohm meter shows continuity between the large terminals and open between the small terminals. Should the small ones read continuity or some resistance reading?
For model number 110.70702990
Hi Marty, Thank you for your question. Both sets of prongs should read 0 ohms at room temperature. If your meter needle does not move or your display does not change, the part is bad and will need to be replaced. I hope that helps. Good luck with your repair.

My dryer is turning on and “working” but it is not heating properly. It is a gas dryer and it doesn’t seem to have a problem igniting. What should I check?
Hi Leo, we recommend testing the coils 279834 to see if they are faulty. You can test them using a multi-meter tool. Please let us know if you have any further questions.

How do you test thermostat internal-bias
For model number lgr4634pq0
Hi Vic, Thank you for your inquiry. To test to see if the internal bias thermostat is working you will need to use a multimeter to check the continuity of the part. I hope this helps. Thank you and have a great day!

Have seen 2 different answers about continuity on thermostat internal bias. One said both should read 0 at room temperature. The other said the small terminals will read an "ohm value". Which is correct?
Hi Tony, Thank you for the question. You would need to check the outer 2 terminals on the thermostat for continuity. If this checks ok then test the inner smaller terminals for resistance of 4.5K ohms. Hope this helps!

None of the components are testing bad. ? The thermal fuse, the high temp sensors, start switch, door switch, all are showing continuity or resistance. The heating element is good. I have only 2 choices left. The timer or the motor. The motor is last as it is hard to get to. The problems began when the timed dry cycle quit heating as it ran. So i used the auto-sense cycle and it worked great. Problem solved for 6 months. Yesterday i put the clothes in and set the timer and pushed start. Nothing! No hum, no buzz, nothing. Not on any cycle. Both parts left are expensive. So, is there a go, no go test for the motor? Would you be inclined to suspect the timer? How can i be sure it is one or the other? Thank you for the help.
For model number EED4400WQ0
Hello Danny, thank you for contacting us. It does not sound like an issue with the motor. It sounds like it would be the timer. The dryer timer is used to control the unit's cycles by regulating the length of time that power is directed to each setting. If it becomes faulty it could cause nothing to happen when you start a cycle or only work on certain cycles. Hope this helps!

How many ohms should the thermostat read when tested with a multi-meter?
For model number KEYE760WWH1
Hi Paul, Thank you for your question. Your meter should be set at the lowest setting. The thermostat should read 0 ohms. If your meter does not move when you test the part, it will have to be replaced. I hope that helps. Good luck with your repair.

Dryer would take forever to dry clothes, even on high setting
I ordered all the thermal sensors for the dryer. They arrived two days later and they were the correct parts. It took me about 1/2 hour to replace all three sensors and now the dryer works like new again. My wife was very pleased, so was I.

intermittant heat
First I shut off the gas supply and disconnected the dryer vent and unpluged the unit so you can access the rear of the dryer. Then I removed the rear cover. This is where you will find your thermostats and fuses. Holding the new part next to the one to be replaced I transfer the wires one at a time so as not to get them mixed up, then unscrew the old part and install the new one. Insert a flat blade screwdriver under the top cover in the 2 front corners to unsnap it from it's clips, also at this time you need to remove the 2 screws that hold the upper part of the lint filter tube to the lid, then lift the lid to expose the drum ( I tilted the dryer back as far as the flex gas line would allow me to and rested the top lid against the wall without removing it, to many wires). Behind the front cover in the top right corner is the plug for the door switch,un-plug it and also there are 2 screws one in each corner. After that lift the front cover straight up and pull it away from the cabinet ( it has clips at the bottom to hold it in place). Reaching under the drum on the right side pull down on the belt tensioner and release the belt from the motor then you can remove the drum. Laying the drum down on it's front edge I removed the rear felt seal and took a piece of sand paper to rough up th old glue and clean off some of the felt that was still stuck to the drum. Following the directions from the seal package I put the glue around the edge of the drum and re-installed the new felt. This is a good time to clean out your dryer, while the glue sets up. A shop vac works the best, but be carefull not to suck up the money, it will help pay for the repair ( I found over a dollar in change ). At this time I also changed the coils on the gas valve, remove the 2 screws that hold the clamp and replace them one at a time. Re-install the drum with the belt on it, fold it and push it through the tensioner and put it on the motor pulley. rotate the drum to make sure that the felt is not kinked under itself, re-install the front cover bottom clips first, then the 2 screws and the plug for the door switch, pull down the lid and snap it in place, before installing the rear cover this is a good time to remove the rear cover to the lint chute and clean in there also ( it's easy to see why there are so many dryer fires). Re- install that cover and the rear cover and vent tube, turn your gas back on and check it for leaks ( even if you didn't disconnect it) plug your dryer back in and get busy catching up on the laundry that you haven't had a chance to do because your dryer broke, then smile and think about all the money you saved by doing this simple repair your self. Thanks Parts Select

Dryer will not turn on
Followed electrical drawing from switch to motor, Thermal fuse was in the line and no power coming through it, removed wire and put together and tested, dryer turned on. Read statements from others at parts select and also bought thermostat because time stopped working last year. Installed both parts and cleaned dryer, works perfect including timer.

Dryer wouldn't heat
I first unplugged the electrical plug, then opened up the dryer, front and back. Once I had diagnosed the problem I unscrewed the thermal fuses and thermostat. Marked which color wire went to which connector and continued to replace one wire at a time. Re-attached the mounting screws, verified all wires were connected, plugged in dryer to test heat cycle. Once the dryer worked correctly I vacuumed all lint and covered it up.

Dryer wouldn't turn on.
When my dryer suddenly stopped functioning, without any prior signs of pending failure, I guessed that it had to be something simple, like a fuse. I did a google search and stumbled across a forum post that described the symptoms (wouldn't turn on), and the poster said that Whirlpool recommends replacing the thermostat whenever the fuse is replaced. The reason for this is that the likely cause of the fuse burning is that the thermostat is no longer properly regulating the temperature range of the heating element.

I disconnected the power source, and then I removed the back cover, and both parts were in plain view, so I simply replaced the wires one by one.

Heat in dryer very low, would take an hour and half to dry a load
First I called an appliance repair place. They charged me $40 to come out and said "the air vent might be clogged". I snaked it out and really wasn't anything in there. So I started thinking it might be a thermostat. After reading the reviews that others posted here, I said, "how hard can it be"? Thanks to PartsSelect putting a diagram (schematic) of the parts, I could see what I was looking for when I removed the back panel. So I took my nutdrivers out, disconnected the vent hose and removed the 10 or so nuts off the back panel & got it out of the way. Took out the vacuum cleaner and sucked all the lint out. Removed the housing where the heating element was and marked on both thermostats and housing where each wires went. As cheap as PartsSelect had the thermostats priced, I figured why not remove the guesswork by buying the highlimit and cycling thermostats and a new heating element too. One screw in each thermostat and out they came. Swapped wires with new thermostats and put them back. With the heating element...it was all one piece, so no fighting to get the element into an old housing. Just swapped them. Put the back panel on and reconnected the vent hose. Cost to repair: about $100. Time for parts to get to me: 2 days. Time to install new parts: about 10 minutes. Knowing that I have a dryer that runs like new AND saving a TON of money on electric bill....THAT is priceless. Thanks PartsSelect!

Thermal fuse blown
I spent nearly an hour trying to self-diagnose the problem before I wised up and found PartSelect.com. After reading just a couple of postings I went back and tested the thermal fuse. It was bad. Other posts suggested I replace the thermostat at the same time, so I ordered both. The parts arrived within three days and the actual repair took less than 10 minutes.

Easy Repair of Whirlpool Combination Washer/Dryer

We were very pleased to receive the parts earlier than expected and they were installed shortly after we got them. I managed to pick up on another problem, possibly the cause of the failure to start with. The heating element had fallen off the insulator and I checked to find that easy fix, securing it back in the insulator, based on a YouTube short that covered all five steps to check when the dryer doesn't dry. Thanks a lot. A load was immediately placed through both washer and dryer and it performed like new. We will use Part Select when ever we need anything.

Easy repair- great part - dryer fixed!

The part was in great condition. Arrived within 3 days. My dryer stopped heating and after trouble shooting the main components we figured out that it was most likely this part. As soon as I plugged it in the element started working and the automatic dryer function started working better than before.

Easy Repair, did not fix the problem of no heat.

Part is fine. Website is great that it gives you a list of parts to go with symptoms! But, I have to be the guy that ends up with the "elusive" problem. Determined that my actual problem is the contacts on the blower motor were fouled. They swing close when the motor is rotating via a "centrifugal" switch. This switch controls the flow of electricity to the heating element. The only way to replace the switch is to buy a whole motor. Cleaned the contacts with a file, seems to be working ok.

Delivery by Puralator was a nightmare

Once received, the part was OK but one of the tines was bent quite a bit. Luckily it was easily bent back into shape.The part was ordered on Oct. 22nd and received a week later. I was notified that the entry # and phone #ers to my townhouse were missing and replied immediately. I'm not sure how it could have taken so long for the message to be relayed to the driver. I guess I shouldn't have be surprised since neither your company nor myself had any luck getting through to Puralator's customer service phone line. PS My brother ordered another part for the same problem and received it almost the next day in his home mailbox. Maybe you should put ENTRY # on your order sheet and phone # required.
