Re: Kenmore dryer 110 86983810.

If your Kenmore dryer has stopped producing heat, chances are the problem lies with the dryer's thermal fuse. A fire-prevention safety device, the thermal fuse is designed to disrupt the flow of electricity to the dryer's heating mechanisms if the dryer temperature reaches a predetermined maximum. Once activated, the thermal fuse must be replaced to restore the heat to your dryer. In Kenmore brand residential dryers, the thermal fuse will be located in one of two places.

Instructions

Front Panel Access
1 Unplug your Kenmore dryer from its power source. Make sure that the appliance is unplugged before proceeding.
2 Use a flathead screwdriver or putty knife to remove the dryer's bottom service panel, sometimes called the toe panel. Slide the screwdriver or putty knife along the top of the toe panel until you've located the toe panel clips. The clips are usually located about four inches in from either side of the service panel. Push down on the toe clips with the screwdriver or putty knife to release. Remove the panel and set it aside.

3 Locate the thermal fuse on your Kenmore dryer. Look for the thermal fuse directly above the dryer's motor; it looks like a white strip with two wires, and is usually mounted off to one side. See Resources for a diagram of thermal components.
Rear Access
4 Disconnect the Kenmore dryer from its power source while locating the thermal fuse.
5 Move the dryer away from the wall so that you can access the back of the appliance.
6 Use a screwdriver to remove the dryer's back panel. Set the panel and loose screws aside until you are ready to replace them.
7 Locate your Kenmore dryer's thermal fuse just above the exhaust port. The thermal fuse looks like a white strip with two connected wires.

Tips & Warnings

Clogged exhaust ports are a common cause of thermal fuse failure. While you've got your Kenmore dryer in pieces, clean out the exhaust ducts to keep it functioning at its best.

Take all proper safety precautions when working with electrical appliances. Make sure that your Kenmore dryer is unplugged before attempting to service it.

Hello,

If your Maytag dryer has mysteriously stopped producing heat, a blown thermal fuse may be the cause of your problem. In Whirlpool dryers,thermal fuses are safety switches that are designed to disrupt the flow of electricity to your dryer's heating mechanisms once the dryer reaches a predetermined maximum temperature, usually somewhere around 180 degrees F.

Thankfully, troubleshooting the thermal fuse in a Maytag dryer is easier than it sounds.

Instructions And Things You'll Needed.

• Screwdriver,Towel,Electrical tape,Replacement thermal fuse, if necessary.

1 Clean out thelint screen in your Maytag clothes dryer. Lint buildup can cause your dryerto overheat, triggering the thermal fuse to disrupt power to your dryer'sheating mechanisms. Take the lint screen out of your Whirlpool dryer and washit in warm water. Dry the screen thoroughly before replacing it.

2 Look behindthe dryer to check its flexible exhaust hose for kinks or obstructions.Disconnect the exhaust hose from the back of your dryer and clean out any lintthat has built up.

3 Go outside andcheck your Maytag dryer's exhaust vent for obstructions. Lint buildup, birdnests or other obstructions in the outside exhaust vent can trigger yourdryer's thermal fuse.

4 Disconnectyour dryer from its power source before attempting to access its thermal fuse.

5 Access the thermal fuse in your Maytag dryer byremoving the back panel. Remove the screws that hold the back panel in placeand it should easily come free.

6 Look betweenthe dryer's blower housing and exhaust to locate its thermal fuse. The thermalfuse in a Whirlpool dryer looks like a white plastic strip that has two wiresconnected to it.

7 Bypass the thermal fuse in your Maytag dryer whileyou perform a quick diagnostic test. Use electrical tape to tape together thetwo wires connected to the thermal fuse. Reassemble your dryer and plug it backin. Set the dryer to a timed heated drying cycle and press "Start."If the dryer produces heat with its thermal fuse bypassed, it means the thermalfuse needs to be replaced.

8 Replace a blown thermal fuse in your Maytag dryer.Disconnect the power and remove the back panel. Remove the electrical tape thatyou used to perform the diagnostic test and disconnect the wires from thethermal fuse. Remove the screws that secure the thermal fuse to the dryer anddiscard the blown fuse. Attach the replacement thermal fuse by replacing andtightening the screws. Attach the wires to the new thermal fuse.

Check the continuity of the thermal fuse located on the blower housing. This thermal fuse is wired in series with the motor and once blown, power to the motor is terminated and the dryer will not start. Also the power to the heating circuit is activated through the motor centrifugal switch. The dryer will therefore not heat once the motor cannot run.

Disconnect power then access the thermal fuse on blower housing.

You can bypass the thermal fuse for troubleshooting purposes by disconnecting the wires and connecting them together. Insulate the connection properly and plug the dryer back in. The thermal fuse is indeed blown and needs to be replaced along with the cycling thermostat if the dryer starts. Do not use the dryer with the thermal fuse bypassed due to fire hazards.

Let us know if you need further advice but indicate the exact model number of the dryer.

Question 1 Is the heat working?

If your getting heat Check to see if your vent is clogged

Unplug it, remove the back, 1. Hi Limit (small limit upper right hand side of this pic) the most frequent problem if dryer RUNS but no heat AND you have
checked the element and found it to be good. 2. heater assembly.
3. 250f limit (if bad no heat, timer won't advance)
4. heater element
5. Fuse(350F), if blown(open) the dryer will NOT run.
(if you do not have a meter remove and inspect this heater coil for breaks).
6. control thermostat
7. heater (warms thermostat to shut it down faster for delicates)

You can use an ohm meter to check t-stats and thermal fuse.

YOU NEED CHEK:
GAS DRYER
1-THERMAL FUSE
2-SENSOR FLAME
3-IGNITOR
4-GAS VALVE
ELECTRIC DRYER

3- HEAT ELEMENT

I had an identical problem to yours this weekend with my Kenmore dryer. There were 2 problems.

1. Timer was broken. Does not advance to "OFF" position on timed dry, however it still works for auto-dry.

2. Thermal fuse was blown. Upon replacing, dryer heated up normally.

I believe when the timer broke, the dryer had kept running and blew the thermal fuse. On Sears' website, thermal fuse is $5.30, timer is roughly $80.

Hi, Here are the obvious parts to check: Heater, High limit, Thermal fuse or thermostats...these are all generally located in the back but some models you access them from front. the most common cause is either heater or thermal fuse, I will include a picture of the thermal fuse. If you test these parts and find they all work you may be looking at a centrifiacal switch problem.

Here is a picture of the thermal fuse check this part first:

Please feel free to contact again if you have any other problems.

Hope this helps.

Most of these issues will need an ohm meter, unless you want to just take a guess.
For Gas dryers.
1. See if the ignitor glows, if not, check the thermal fuse. (if the lint screen is on top, the fuse is accessed behind the back panel, it's small and white, next to the bulkier thermostat. If the lint screen is in the front panel, the thermal fuse is mounted on top of the blower wheel housing, accessed behind the bottom-front or "kick" panel. The fuse should read 0 to .2 ohms at the most, technically is should be zero. If that checks ok, check the ignitor itself, which has a wire harness that connects about 6" from the ignitor. Should be around 50 ohms... a faulty ignitor would read infinite ohms (open).
2. If the ignitor does glow, and you hear a click, but there is no flame, replace the valve coils, (two small cylindrical objects mounted on the valve) Part # 279834. This is assuming your gas is ON.

If Electric, it would not be the fuse, as on electric dryers it is also in the motor circuit, and the dryer would not run at all. Check the heating element, should be around 9-11 ohms. If good, check all thermostats (operating, hi-limit, thermal cutoff). Infinite ohms is bad. Hopefully it's not more complicated than this, or it can get weird..... Hope this helps.
