Can you temporarily bypass a thermal fuse?
Temporarily tape the two wires that go to the thermal fuse together to essentially "bypass" or "jump" the thermal fuse. Use electrical tape to properly insulate the connection and avoid contact of bare wire contacts with the dryer cabinet.
Are thermal fuses universal?

Can you tell if a thermal fuse is blown?
Multimeter Test 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.

Will a dryer turn on if the thermal fuse is blown?
A gas dryer will run but won't heat if its thermal fuse blows because the dryer overheated (usually because the vent is clogged, so check the vent path). Use a multimeter to check the thermal fuse and replace the thermal fuse if you don't' measure continuity.
What causes a thermal fuse to fail?
The main reason that a thermal fuse will blow is a blocked exhaust vent. This is because when the exhaust vent is blocked hot air cannot properly get distributed out of the dryer and this causes it to overheat. So, if you give the exhaust vent a regular clean, it should stop the thermal fuse from blowing again.
What happens when the thermal fuse goes out?
A tripped thermal fuse can have two effects. In some dryers, it simply shuts off electricity to the heating element. This means a dryer will run, but it will only air-dry clothing. In other models, the thermal fuse stops power completely.

Is it worth replacing the heating element in a dryer?
If your dryer's heating element burns out more than once within a year or two, the thermal fuse, which is supposed to protect it, is probably defective, so it's a good idea to replace it. The temperature in the heating chamber may also be too high, and that may be caused by poor venting.

Are there different types of thermal fuses?
There're two types of thermal fuse: Alloy Type and Organic type.
How do I choose a thermal fuse?
The thermal fuse is generally connected in series in the circuit when it is used. Therefore, when choosing a thermal fuse, its rated current must be greater than the current used in the circuit. Never allow the current through the thermal fuse to exceed the specified rated current.
What's the difference between a thermal fuse and a regular fuse?
Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature and not to excessive current (unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature).

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.
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.
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.
What happens if you replace a fuse?
If you just simply replace the fuse, there is a good chance the fuse will blow again.
How long is a fuse holder?
The power cord will lead to the fuse holder. Be careful not to touch any electrical parts or interior metal objects. The fuse will be one to two inches long. It may be a glass fuse with a filament, or a ceramic fuse.
How to tell if a glass fuse is blown?
It’s easy to tell if a glass fuse is blown; it will show scorch marks, and the filament will be melted. To check a ceramic fuse, use an ohmmeter or continuity tester. With an ohmmeter or multimeter, you should see a reading close to zero ohms if the fuse is intact, or infinite if it’s blown. If a continuity tester indicates continuity ...
Why does my microwave keep throwing a breaker?
If it keeps throwing the breaker, though, you should check why. You might be running too many appliances on the same circuit, or the oven could be defective. Unfortunately, microwave fuses are rarely in a convenient location. You’ll have to do some disassembly to get to the fuse. Typically this means removing a panel.
Can you get a shock from a microwave caster?
If you don’t know a capacitor from a caster, leave the matter to a professional. Even an unplugged microwave oven may contain high voltages and could give you a dangerous shock. If you’re learning, be sure you have expert supervision, and follow all instructions.
