What does a dryer thermal cut off fuse do?
The dryer's thermal fuse is a non-resettable safety fuse that is designed to break electrical contact to the dryer's heater if the dryer becomes too hot. This fuse will often burn out due to clogged dryer ducting or a defective cycling thermostat.

What is the difference between a thermal fuse and thermal cutoff?
Thermal Fuse and Thermal Switch both are electrical safety devices also known as safety cutoff. In both electrical and electronic circuits, appliances, devices they are used. As its name suggests thermal cutoff, so it will break or cut off the circuit and its operation is related to the thermal operation.
How do I know if my thermal switch is working?
Watch the needle on the digital multimeter display to determine if your thermal overload switch needs to be replaced. A functional thermal overload switch will cause the needle to move to "0". If your thermal overload switch is faulty, the needle on the digital multimeter will not move at all.
Do thermal fuses wear out?
A thermal fuse must be replaced when it fails or is triggered. Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature.

Is there a reset button on a dryer?
Many dryers are equipped with a reset button on the control panel. If the motor won't run, let the dryer cool for about ten minutes. Then push the reset button. If there are no problems with the motor, switches, or electrical system, this should restart the dryer.
What is thermal cutoff switch?
What is a Thermal Cutoff Switch? A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change.
Why are thermal switches considered cut off switches?
Thermal switches are specified as cut-off switches because they represent a straight-forward approach to shutting down a system if a critical temperature is reached. The simplicity of an electromechanical thermal switch is what makes this approach so desirable to designers, as they are passive devices which require no power, and will reliably change state at the specified set point. Applications include:
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.
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 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.
How does a thermal cutoff work?
The thermal cutoff isn't the same as a thermal fuse. The fuse controls the dryer's heating element whereas the cutoff controls the motor. When the fuse blows, the dryer won't get hot, but when the cutoff blows, the tumbler won't spin. The location of the cutoff varies according to dryer model, but it's usually attached to the dryer housing. It monitors the temperature inside the housing, and when that temperature exceeds its limit, it melts, thereby opening the circuit to the motor. Since it only responds to temperature, its failure usually doesn't signify an electrical problem.
What happens when a thermal cutoff blows?
When a thermal cutoff blows, you have to replace it to get the dryer working again. If the new one also blows, you need to troubleshoot the cause of the excessive heat before you install another one.
Where is the cutoff on a dryer?
The location of the cutoff varies according to dryer model, but it's usually attached to the dryer housing . It monitors the temperature inside the housing, and when that temperature exceeds its limit, it melts, thereby opening the circuit to the motor.
Can a cycling thermostat stay on when it is off?
If it has shorted, it may stay on even when the cycling thermostat turns it off. A visual inspection may reveal that it's touching some part of the assembly casing, but if not, you should unplug the dryer, remove the heater assembly and test it for continuity with an ohmmeter.
What Is a Thermal Switch & How Does It Work?
A thermal switch, aka thermal cut-off switch, is an electromechanical device that activates and deactivates electrical flow based on temperature changes.
Why Does My Water Heater Thermal Switch Keep Tripping?
There can be multiple reasons why your water heater thermal switch keeps tripping. Let's delve in:
Is It Safe To Bypass A Thermal Switch?
You might be wondering whether it is a bad idea not to use a thermal switch. Well, it's designed to ensure safety; therefore, you cannot disregard its need and importance.
How To Bypass Thermal Switch On Water Heater
Your water heater's thermal fuse looks like a thin white plastic strip with wires coming out of each end. To bypass, use an electrical tape or a wire nut to hold both ends in place.
How To Reset The Thermal Switch On A Water Heater
Thermal switches cut off critical machinery current when temperature limits exceed to prevent any potential failure or burnout.
Conclusion
Bypassing a thermal switch on a water heater can be considered quite unsafe for several reasons. That is why you mustn't do it without proper safety gear. For best results, please call in a professional!
