There are two mounting screws holding your thermal fuse in place. Be sure your dryer is unplugged for this. – Disconnect Wiresĭisconnect the two sets of wires connected to the two prongs on the back of the thermal switch. It is likely located in the middle of the back of your dryer components. You can match it visually with your replacement part. The thermal fuse is very small and either white or silver with two wire nodes on the back. Remove the Blown Thermal Fuse – Identify Thermal Fuse Pull away the back panel from the dryer and set it, along with its screws, aside where they won’t be in the way.
#Dryer fuse driver
You will likely need the nut driver for this task. Standing behind your dryer, remove the mounting screws holding on the large back panel.
Remove the Back Panel – Remove Back Panel Mounting Screws You’ll need enough room to stand and work behind the dryer. Grasp your dryer from the top edge and wiggle it out away from the wall. So you’ll want to wear work gloves to protect your hands. The edges of appliance panels tend to be sharp because they have not been sanded for consumer access. Pull the plug out from the wall and if you can’t reach the plug, remember to unplug your dryer after you pull your dryer away from the wall. Naturally, your fuse is an electrical component which means you need to unplug your dryer before starting the technical part of this repair. This clearing will ensure that exhaust dryer air can flow and your next fuse won’t blow because hot air is stopped by lint. Brush the duct out with your duct cleaning brush. You can also just reach in with your gloved hand, but prepared to get dusty. If you have a shop vac or a sturdy normal vacuum cleaner with a hose, use it to clean the lint out of the vent. Then detach one end of vent and shake it out. While cleaning the lint trap and vent won’t fix your fuse, it will prevent your new fuse from tripping for the exact same reason.Ĭlear your lint trap. What this means is that there’s too much lint in the flexible silver tube behind your dryer or a vent opening connected to that tube. The most common cause of a thermal fuse break is a clogged vent. For this repair, you’ll need two different kinds of screwdrivers, work gloves, vacuum supplies, and of course a replacement thermal fuse that suits the make and model of your dryer. It’s important to have all your supplies together before you start a repair so that you don’t have to stop in the middle to find a tool. However, once the thermal fuse trips once, it must be changed before your drive motor will reengage and your dryer is useful again. Without the thermal fuse, dryers which are high-voltage and heat generating would be much more dangerous to have in homes. It will still light up and respond to button presses if you have buttons, but it won’t turn the drive motor or begin creating heat. The thermal fuse controls power to the drive motor. It’s an important part but once it blows, it is blown and needs to be replaced. If the air in the exhaust vent gets too hot, the fuse blows to prevent your dryer from overheating and creating a fire hazard.
It actually measures the heat of the air leaving your dryer out the exhaust vent. We stock a range of PCB mount thermal fuses in both axial and radial lead types.Your dryer’s thermal fuse is a small safety feature that ensures that the inside of your dryer doesn’t get too hot. The allowable maximum voltage which can be applied to the thermal fuse. The allowable maximum current which the thermal fuse is able to carry. The highest temperature of the thermal fuse at which it does not function or the functioning temperature does not become higher remarkably after being exposed for a certain amount of time.
The highest temperature of the thermal fuse at which continuity does not occur for 10 minutes after the function of the thermal fuse. The highest temperature of the thermal fuse at which it does not open the circuit while passing rated current for 168 hours. Tolerance for METI is ☗ C except some types. Tolerance of rated functioning temperature is +0, -10 C for IEC 60691. Rating of the functioning temperature based on safety standards.
The functioning temperature is not the Rated Functioning Temperature. The temperature at which the thermal fuse opens (fuses off) while passing 0.1 amp or less in a controlled oil bath at arise of 1 C per minute. Opening Temperature / Cut-off Temperature The following definitions apply to our range of Elcut thermal fuses:
