Household dryers are necessary appliances that adeptly remove moisture from clothes through hot air blown via a rotating drum. Nevertheless, malfunctioning can happen due to predicaments like thermal fuses being blown.
If a dryer overheats, a thermal fuse is employed as a safety device that shuts it down to prevent the risk of fire. A faulty thermal fuse can cause operational issues in your dryer and detecting the problem may be challenging, particularly if you’re not familiar with its warning indications.

Indications That Your Thermal Fuse Is Damaged and Needs Replacing
Here are some common visible signs to look out for if you suspect your appliance’s thermal fuse is blown:
Short Circuit
If a short circuit occurs, other components in the circuit may be safeguarded by blowing the thermal fuse. A sudden loss of power may also be experienced as a result. Electrical faults usually happen when an electric current deviates from its intended path, leading to overloading in wires nearby. This is often caused by insufficient resistance coming from insulation or circuit breakers.
Fault in the ground
The thermal fuse could also be triggered by a ground fault. Investigate for any malfunctioning or unplugged appliances that may have caused the incident. It’s critical to not handle adjacent outlets or devices in case of overheating faults as they can electrocute you. Instead, steer clear of the affected location and call on an emergency electrician nearby for assistance.
Electrical outlets that have suffered damage
When your electrical outlets become damaged or faulty, they may trigger a thermal fuse to blow. Thus, it’s important to examine them and replace any that are worn-out or broken. Signs of damage include burn marks, melting parts, chips and cracks in the outlet structure as well as warmth when touched. If you suspect an issue with your outlet(s), consider hiring a professional for inspection purposes only; don’t attempt repairs on your own unless experienced in this area!
Wire Damage
If the wires appear frayed or damaged, it may result in a blown thermal fuse. Ensure that you inspect wiring for any signs of harm and replace them as necessary. Check your wall outlets to see if there are dimming lights, discoloration, smoke generation with sensations of warmth or vibration before proceeding further.
Circuit Overload
Excessive heat and pressure on the thermal fuse caused by an overloaded circuit may result in blowing it. To resolve this, removing some of the devices connected to a single circuit can be attempted as a possible solution.
Incorrect Fuse Type
When a circuit is overloaded, it can exert an enormous amount of stress on the thermal fuse causing it to blow. If you notice that too many appliances are plugged into one circuit, attempt disconnecting some and observe if there are any changes.
Electrical System in a State of Decay
Upgrading your electrical system is advisable if your device operates on an old or obsolete network, as it can put undue strain on the thermal fuse and cause heating problems.
Step-by-Step Guide on Testing Your Thermal Fuse
While some thermal fuses exhibit visible cracks and gray metallic ash when blown, others may appear to be in good condition. Additionally, numerous fuses are not transparent; therefore you must scrutinize them closely to inspect the interior.
This is a method to check if your thermal fuse has blown.
Step 1: Disconnect the appliance from its power source.
As an additional safety measure, put on rubber gloves and stand on a rubber mat before removing the thermal fuses. To ensure safety and prevent fires, turn off the power supply to the circuit box using the main breaker.
Step 2: Access the switch by removing the back panel.
To find a clothes dryer’s thermal overload switch, usually housed behind the back panels or bottom toe, one should examine these areas. In order to remove the back panel and access the switch, simply unscrew its mounting screw.
Note that specific appliance panels are secured by small metal clips, which can be detached using a putty knife or flathead screwdriver to apply pressure on the back panel.
Step 3: Find a narrow strip that has two wires and separate it from the other components.
The thermal reset and overload switch can be recognized as a slim, white plastic strip that has two wires attached to it. To disconnect the thermal overload switch, cautiously pull on the pair of wires.
Step 4: Activate your multimeter.
To assess continuity and detect faults in your thermal overload switch, activate your digital multimeter for temperature measurement and configure it to Rx1 resistance reading mode.
Step 5: Place your multimeter leads in contact with each other.
To ascertain whether a new thermal overload switch is necessary, touch the leads and monitor the digital multimeter’s display. If it reads “0”, then the switch is functioning properly; however, if there’s no movement in the needle on your device, this indicates that you need to replace faulty parts.
Step-by-Step Guide To Replace Your Thermal Fuse
With just a few tools, an individual who enjoys do-it-yourself projects can easily replace a blown thermal fuse. This not only provides the satisfaction of fixing the problem on one’s own but also saves money that would have been spent on a service call.
Below are comprehensive guidelines to assist you in replacing a thermal fuse within your dryer.
Necessary Tools
Driver for nuts.
The term “multimeter” can be rephrased as a device that measures multiple electrical quantities such as voltage, current, and resistance.
Pliers with pointed, tapered jaws
Tips for Ensuring Safety
Before commencing any replacement work, ensure that the power supply has been disconnected.
To prevent harm, ensure to wear safety gloves and glasses for safeguarding your eyes and hands.
Make sure to let the appliance cool down before you begin any work.
To begin, take off the back panel
To have the thermal fuse replaced, carefully remove your dryer by pulling it out and accessing its backside for all repair work. The following step is to employ a nut driver in loosening and extracting every screw that secures the rear panel of your dryer.
Find the Thermal Fuse
The thermal fuse can be found near the blower housing of the dryer, and it has two leads attached to it for easy identification. To disconnect this component, securely grip both ends of a jumper wire (one male and one female) connected to each lead and gently pull them towards you.
Involves the removal of the old thermal fuse
In order to eliminate the thermal fuse screw, detach the connectors and utilize a nut driver. It’s important to keep in mind that many thermal fuses possess a flap on one extremity of their exhaust tube which necessitates an oscillating movement to be dislodged.
The fourth step involves the installation of the new thermal fuse.
To install the new fuse, slide in the open end that has a notch, reattach wire terminals and lastly secure with screw.
Attach the Back Panel Again
Before testing your repair, make sure to attach the panel using the nine-quarter-inch screws.
Attempt to Test Your Clothing Dryer
Plug in the dryer and slide it approximately one meter away from the wall before turning it on to confirm that it’s working properly.
