All the heating and temperature control components are located in the back of the dryer. To access, unplug the dryer and remove the exhaust vent hose. Turn the the dryer around so you can view the back and remove the back panel. With the panel removed, the component locations are as follows:

Right-Hand Side:

1. Heating element - located inside the heater box. If bad, the dryer will run, but will not heat. A good reading is about 9 to 13 ohms.

2. Thermal Cut-Out (TCO) - located on the outside of the heater box on the end opposite the heating element terminals. If bad, the dryer will run, but will not heat. A good reading is a short (0 ohms).

3. Hi-Limit Thermostat - located on the outside of the heater box adjacent to the heating element terminals. It works in conjunction with the TCO to help regulate the drum internal temperature. A good reading is a short (0 ohms).

NOTE: If either the TCO or Hi-Limit Thermostat are found to be defective, it is recommended that you replace BOTH components to prevent premature failure. These two components are commonly sold as a set.

Left-Hand Side:

1. Thermal Fuse - located on the blower fan housing. It is a small white plastic looking component with two wires attached. If defective, the dryer will not run at all. If the component is good it should read a short (0 ohms).

2. Internal Bias Thermostat - located on the blower fan housing adjacent to the Thermal Fuse. It has four wires attached to it.

NOTE: All resistance checks should be performed with the component terminal wires disconnected to prevent false readings.

If you have any questions, you can refer to searspartsdirect.com for some helpful exploded view diagrams to assist you. The components I mention are listed under the "Bulkhead" heading as follows:

Item 6 - TCO/Hi-Limit Thermostat replacement kit
Item 15 - Hi-Limit Thermostat sold separately
Item 17 - Heating Element
Item 23 - Thermal Fuse
Item 24 - Internal Bias Thermostat

If you need further assistance, please let me know. I hope this helps you.

Most commonly it's the white thermal fuse in the back of the dryer, but it could be any number of things including a door switch, burned wire, bad motor, bad timer, etc. Try the thermal fuse first. It's easiest and cheapest.

I have a Kenmore Dryer, Model 96292110. It runs, but it does not heat the air. I have checked the circuit breakers. They are fine.


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.

Thanks for using fixya.

Thermal Fuse

Item #2986 (OEM Part)
$10.70

Thermal fuse. If the dryer overheats, this device stops the flow of electricity to the heat source and/or the entire dryer. It is located on the blower housing and cannot be reset. The most common cause for overheating is a vent tube clogged with lint, a birds nest or other debris.

    Removing a part form a Whirlpool Electric Dryer


    The thermal fuse is located on the outside of the blower housing. To get access to the thermal fuse you will need to remove the back panel of your Whirlpool dryer.

    How do you check it:
    Before you do any repairs on your dryer, you will need to disconnect the dryer from the wall outlet.


    After removing the back panel, remove one wire from the Whirlpool dryer thermal fuse and take a reading between the two terminal on the thermal fuse.
    The reading should be 0 ohms, if the reading is infinity, the thermal fuse is bad and it must be replace. When you find a bad thermal fuse, you will need to replace the operating thermostat too.

    The operating thermostat opens at 155 degrees and the thermal fuse blows at 196.

    These means that operating thermostat did not open at 155 and that is why the thermal fuse failed.

    The thermal fuse


    Check yo see if you have any air restrictions by feeling the vent that exits the house. You should have strong air flow. Any restriction, even if small will cause the dryer to overheat and blow the fuse. Thanks Dave www.washermd.com
