A cycling 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 and will then turn off and then on again once it has dropped by 25 degrees. If your dryer is not giving off enough heat, is over-heating, is not turning on, or is having issues with the timer functionality, this could indicate an issue with the thermostat. The installation of the cycling thermostat is simple and the only tool required is a 1/4 inch nut driver (and gloves for safety).

This part works with the following brands: Whirlpool, Kenmore, Maytag, KitchenAid, Roper, Estate, Crosley, Inglis, Amana, Admiral, Magic Chef, Jenn-Air.

Question:

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?

Leo
Answer:

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.

Question:

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.

Dylan
Answer:

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!

Question:

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?

Kealan
Answer:

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!

My dryer did not heat up

Prelude to this was 2 years ago we had the same problem, called Sears and $200 later we had a new $16 dollar part, the repair guy was kind enough to tell me what he did, and I saved the fuse he replaced. So when it happened again this summer, I went through a couple of sites (obviously including this one) to find parts, started with the fuse he had replaced, which was not the problem this time, went on to the next likely, and on through about 5 key elements (all under $20) until I found the coils on the burner assembly were the problem. All in all the repairs were pretty simple, and once I figured out how to dismantle the cabinet safely. I am VERY happy with the timely replacement parts (shipped very quickly) and when your dryer isn't working-things pile up pretty quickly. The dryer is working like a charm again. Thanks! -Mike

Timer would not advance/no heat

This was so easy with the Partselect video. I removed the back of the dryer (9 screws) with a pair of pliers. Took a picture of the cycling thermostat with a digital camara, just in case I mixed up the wires. I removed 4 wires and two screws, screwed in the new cycling thermostat and reattached the wires. NOTE: wires can be pretty tight, a pair of needle nose pliers would have helped.

Unfortunately, my wife did not mention that the dryer was not getting hot, only that the timer did not advance. I hopped back online, ordered the heating element and the thermal fuse, debated about paying for a next day delivery and decided against it. I placed the order on a Thursday night at 10:00 p.m. It shipped Friday and arrived on Saturday evening. I was not expecting it until Wednesday!!

The Dryer is working like new, my wife thinks that I'm a genious and I'm just happy I did not have to help lug clothes to the laundromat Sunday!!!

Dryer would not start

After diagnosing the fuse associated with this part as being the problem and ordering it from Sears I came across this web site and compared prices. I found the repair stories and discovered that Whirlpool which is the manufacturer for Kenmore, recommends replacing the thermostat along with the fuse as the thermostat is the likely cause for blowing the fuse. I ordered the thermostat from PartSelect and had it the next day while Sears was like 5 days. If I need repair parts in the future I'll order from PartSelect.

Dryer would not heat clothes

Unplugged the dryer from the electrical outlet.
Pulled out the dryer from against the wall, allowing room for me to work.
Turned off the gas to the dryer.
Removed all the screws from the black panel covering the cabinet, not from the console control.
Pulled off the black panel.
Located Thermal Fuse (two wires coming from it) at the bottom, just above Thermostat (several wires coming from it). Removed single screw attaching the Fuse.
Tested Thermal Fuse with MultiMeter set to Ohm for continuity. No continuity means the fuse was blown so I needed to replace it.

Since the back panel was already removed, I replaced the Thermostat for good measure. Just remembered to mark which wires went where and replaced Thermostat.
You can test before replacing everything.

Dryer tumbles but no heat

After reading most of the repair stories i decided that these two pieces were the main culprits of not having heat so i just decided to jump in and do it myself. This repair was fairly simple. I unplugged the dryer first. The dryer was a gas dryer but i did not turn off the gas. I then took the off the large metal cover on the back of the dryer as well as the air vent coming in. This required removing eight screws from the panel. Once i took off the plate, the fuse and thermostat were in plain view. I then removed the screws which secured these pieces in place and unattached the wires connected to them. There were about four wires for each piece and i just reattached the wires to the exact same spot on the new pieces. Just remember which wire goes with the right connection. They just slid onto the connector. The only difficulty was that a couple of the wires were a little snug on the connection so i had to use small pliers to pry them free. Once they were in place and i put the panel back on and plugged the dryer back on. I started it and within a few seconds the dryer kicked on and we had heat. These two procedures were quick and very easy for even the simplest handy person.

Replaced thermal fuse, cyling thermal, then replaced thermostat 205F, ptoblems still remained.
Using ohmmeter measured and inspected all components . Found that the valve coils a little bit stick to the shaft. Orderd the two terminal gas valve coil and secondary coil valve - three terminal and replaced. Problem solved. :-)

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.

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.
