Remove the back access panel on the dryer, and look for the exhaust duct near the bottom of the unit. The thermal fuse is either circular or oblong, often white plastic with black material in the center and two wire leads. The thermal fuse is mounted on the exhaust duct.
Are thermal fuses for dryers universal?
A universal part, widely used in dryers of various brands: Whirlpool, Maytag, Kenmore, Crosley, Amana, Admiral, Estate, Roper, etc. Different from Thermostat, the Fuse is not resettable.
What happens when a dryer thermal fuse blows?
A thermal fuse will blow when the temperature gets too high, not when it’s drawing too much current. When it blows, the dryer stops generating heat. It’s necessary to replace it before the dryer will run again.
Can you run a dryer without a thermal fuse?
Bypassing a Dryer Thermal Fuse
Operating a dryer with a bypassed thermal fuse is both unnecessary and unsafe, so a bypass should only be done long enough to troubleshoot a potential problem. Even short usage without a thermal fuse in place could result in irreparable damage to the appliance or injury to yourself.
How do I know if my thermal fuse is bad?
How to tell if a thermal fuse has blown? To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead. If the multimeter needle fails to move, this indicates the thermal fuse has blown.
How do you reset the thermal fuse on a Whirlpool dryer?
You can reset a Whirlpool dryer by pressing and holding the start button for a few seconds. This should start the reset automatically. If it doesn’t you might have you work your way through some of the individual parts of the cycle until it finally will reset on its own.
How do you tell if a thermal fuse is blown without a multimeter?
If you do not have a multimeter, you can also test whether or not the fuse is working by bypassing the fuse itself. Simply detach the wires from the fuse, wire them together using a jumper wire and attempt to operate the dryer.
How do I know what thermal fuse I need?
Remove the two wire leads from the thermal fuse and touch a multitester probe to each wire terminal on the fuse. If you get a reading of infinity, the fuse is fine. Any reading less than infinity indicates a triggered thermal fuse you will need to replace.
How many thermal fuses does a dryer have?
Electric dryers use two household fuses or circuit breakers. The drum can still turn if just one fuse is blown, but there will be no heat. You may need to replace both fuses or reset both circuit breakers. If the dryer’s thermal fuse has blown due to a power surge or other mechanical problem, the dryer won’t heat.
Is a thermal fuse one time use?
A thermal fuse is a cutoff which uses a one-time fusible link. Unlike a thermal switch which may automatically reset itself when the temperature drops, the thermal fuse is more like an electrical fuse: a single-use device that cannot be reset and must be replaced when it fails or is triggered.
Why would a dryer run but not heat?
Common reasons for an electric or gas dryer not heating are a tripped circuit breaker, clogged vent, and no gas flow. Other potential reasons include a faulty thermal fuse and broken heating element.
How many amps is a thermal fuse?
Providing reliable back-up protection for temperature controlling thermostats and other over-temperature conditions, the G4 series MICROTEMP thermal fuse is the industry standard for over-temperature protection. The G4 is rated for continuous operating currents up to 10 amps @ 250VAC.
