Why are thermal fuses different from traditional fuses?
They’re different than traditional fuses because they only interrupt current flows when there is enough of a problem to cause overheating. When the fuse becomes overheated itself, the sensors detect the heat and interrupt the current. Once a thermal fuse does its job it must be replaced immediately.
Where do you find thermal fuses?
Thermal fuses are easy to find if you know where to look. Most hardware stores carry them. They are also sold in home improvement stores, appliance stores, and you can also order them online. The average cost is $10 per fuse.
What is a thermal fuse?
According to SWE, a thermal fuse is a component that serves as a safety device. It is also known as a thermal cutoff. It opens circuits to prevent overheating. Thermal fuses are designed to detect heat that arises from an overcurrent that occurs within an electrical system. The cause for the overcurrent could either be due to a breakdown in a component or a short circuit.
How do you know if a thermal fuse is working?
According to Hunker, you should use a multimeter to test a thermal fuse. Simply touch the right side of the device’s lead to the right side of the fuse. You should also repeat the process on the left multimeter lead. If the needle moves this means that the fuse is still in operation. If the needle doesn’t move, then you can assume that the fuse is blown and must be replaced. Various appliances that use thermal fuses will stop working if the fuse is blown. If there are no other defects or problems with the unit, then simply replacing the thermal fuse may make them function normally again.
How do you replace a thermal fuse?
After testing a thermal fuse as recommended, a blown fuse is not that difficult to replace, depending on the kind of appliance it is in. For a clothing dryer, in most cases, the back panel must be removed. The fuse is usually found behind the back panel. It’s always recommended to refer to the owner’s manual of any appliance for the exact placement of the thermal fuse. Sometimes it is located in the top part of the dryer. If you don’t have a paper manual you can usually find one online. Simply remove the old blown fuse and replace it with a compatible model.
What appliances use thermal fuses?
Some common household appliances that use thermal fuses include hairdryers and clothing dryers that are used for everyday laundering tasks. They are also used in the construction of coffee makers. The thermal fuse works by disconnecting the current to the heating element when there is a faulty thermostat or some other type of malfunction.
What is the difference between thermal fuse and overcurrent?
A second difference is that a thermal fuse will only react when there is an excess in heat, versus excessive current. The overcurrent must be high enough to cause an excessive amount of heat that can be detected by the thermal fuse. The heat causes the thermal fuse to heat up to trigger the response that provides safety from electrical fires.
Why do dryers need thermal fuse?
The role of the thermal fuse is to prevent fires, by detecting when the dryer drum is overheating, and tripping in response. The dryer will therefore stop running. A thermal fuse is a one-time use component, but luckily, they are inexpensive and easy to replace. Remember, as the thermal fuse is a safety component, do not use the dryer again until you have replaced it. With a new understanding of what the dryer thermal fuse does, you might still be wondering, where is the thermal fuse on a dryer?
Where is the thermal fuse located?

Why won't my dryer turn on?
In many cases, if your dryer has a malfunctioning thermal fuse, the dryer will not turn on at all. However, with some other dryers’ models, the drum will turn and the dryer will operate, but the heating element will not turn on to heat up the clothing inside the dryer. This could cause you to open up your clothes dryer only to find out that all of your clothing is still wet. Keep in mind that symptoms can vary by dryer model, even if two of them come from the same manufacturer.
How to check if a thermal fuse is working?
It’s not something that should be used as a permanent repair. This process involves disconnecting the wires from the fuse and then tying them together using a jumper wire. After you have completed that, plug in the dryer and turn it on before checking whether it operates. If it starts running and has heat, this signifies that the thermal fuse has burned out and will need to be replaced.
How to check continuity of thermal fuse?
The first step here is to press the power button on your digital multimeter. Turn the control dial or press the button on the multimeter to test for continuity. Take the left lead on the multimeter and press it against the left side of the thermal fuse . The right lead should be placed on the right side of the fuse. Watch the needle on the multimeter for movement. If there is no movement, that means there is no continuity, and the thermal fuse needs to be replaced.
Where is the thermal fuse on a gas dryer?

What is thermal fuse?
The thermal fuse is different from the thermal cutoff. The thermal fuse stops the dryer from operating, tumble and heat included.
Why is my dryer vent clogged?
Make sure that the vent is clean and that it has an unobstructed path. It’s also possible that the fuse has reached its end of life, or that there’s some other failure in the appliance that’s making it overheat. If the dryer doesn’t have clearance on all sides, or if it’s too close to a furnace, that might be a contributing factor.
What to do if fuse is blown?
If you can identify the underlying problem, fix it first. Then you can replace the fuse. If the fuse is blown, other components responsible for heat have probably been stressed. Replacing those components could save another repair in the near future.
How to tell if a fuse is blown?
If it shows less than one ohm, the fuse is still working and the problem lies somewhere else. If it shows an infinite amount of resistance, then the fuse is blown.
How to test if a fuse is failing?
The simplest test is to remove the fuse and use a re-settable fuse in it’s place. That’s not a fix, just a way to test for the real issue causing the fuse to fail, and it’s very dangerous to bypass the fuse for normal operation!

In past years, house fires were commonly caused by failed dryers. However, thanks to these components, this is a thing of the past, as both parts work to prevent fires.
Why does my blower fuse overheat?
When this occurs, it will cause the fuse to overheat and blow due to heat build-up. If this is the issue, you’ll need to access the blower wheel and clean all lint and other debris from around it. Then you will need to locate and replace the thermal fuse.
What is the thermal fuse wrapped in?
The Thermal Fuse is Wrapped with Lint. Lint can bypass the trap sometimes, and end up in the wrong places inside your dryer. Once such place it can end up is wrapped around the thermal fuse inside the blower wheel. When this occurs, it will cause the fuse to overheat and blow due to heat build-up.
What are the parts of a dryer that go bad?
Dryers have many parts that can go bad. Two such part are the thermal (limit) fuse and the thermal cutoff.
Why does my dryer overheat?
When dryer hoses or vent lines become clogged it prevents proper air circulation, which will eventually cause your dryer to overheat.
Why does my Whirlpool dryer keep tripping?
Another common reason for Whirlpool and Maytag dryers, that this particular thermal fuse keeps tripping is due to a failed relay on the control board.
Where is the thermal fuse on a Whirlpool dryer?
Whirlpool – made 29-inch (wide) machines (Most Kenmores, Kitchenaid, Roper, Estate): you’ll find the thermal fuse ‘reading’ the heating element’s temperature from the side of the ‘can’ where the element lives, in the back of the dryer . This one’s the device mounted highest on the side of the ‘can’, directly above the safety thermostat, which is down near the element leads.
What is thermal fuses?
Thermal fuses, or thermal cutoffs, are small electrical temperature sensitive ‘switches’ designed to interrupt electrical current flow when heated to their specific rated 'trip' temperature. Unlike a thermostat, which automatically resets itself when the temperature drops, thermal fuses are more like their cousins, electrical fuses, ...
Why do we need a thermal fuse?
In addition to their legally mandated application in modern clothes dryers (since the 1980’s), thermal fuses are used as safety devices in other heat-producing appliances like coffee makers and hair dryers. They disconnect the flow of current to the heating element in case of malfunction (such as a defective thermostat or clogged dryer vent) that allows the temperature to rise to dangerous levels, possibly starting a fire.
How to test if a dryer is open?
To test one, leave it in the dryer, power the dryer down, bypass the thermal device, and power up and run the dryer with it bypassed or jumpered. If the dryer now heats, you immediately know it’s open and should be replaced.
Where is the thermal fuse on a Maytag?
Note: most newer Maytag ‘Dependable Care’ machines (the last ‘real’ Maytags <grin>) have their thermal fuse on the side of their element can, similar to the Whirlpool 27 inchers. Very similar to the Speed Queen front panel: two screws are removed from the bottom, and it’s swung upward and unhooked to get access to the element area.
Is a thermal fuse a fault?
OK, to be fair, this failure’s usually not the thermal fuse’s fault, but the real cause lies in a partially (or completely) clogged dryer vent system. In those cases, the thermal fuse is just doing the job it was designed for.
Where is the thermal back on a can?
The thermal’s furthest back on the can, behind the safety tstat. Easy to get to: use a putty knife in its top edge to release the bottom front panel, and swing the panel down. It’s easiest to remove the heat shield over the front of the element to get a little extra room to work.
