Before making the repair, however, you will need to look up what type of thermal fuse your particular model of dryer uses. Thankfully, a thermal fuse is really rather easy to replace. Once tripped, it needs to be replaced to restore function. Like many fuses, the thermal fuse in your dryer is a one-time use. However, in some dryers, this may only cut the heating element. The fuse is designed so that if the dryer gets too hot, the fuse will trip and shut off dryers. The thermal fuse became mandatory in dryers as a safety mechanism. While a dryer that won’t start or won’t produce heat can be caused by a myriad of different issues, the key factor in a blown fuse is that it stopped mid-cycle. The coils should only be touching the porcelain holders on the element.If your dryer suddenly shut off mid-cycle and now will not turn on again, or turns on but does not produce heat, you may be looking at a blown thermal fuse. This will cause your heating element to overheat very quick and will either need to be replaced or bent back into the correct position. Grounded Heating Element If the coils on your electric dryer heating element are touching the cover or any other metal then your dryer heating element is grounded.If not functioning correctly the heating element will not turn off and the dryer will over heat. Although not as common to brake it is possible it is faulty. Thermostat Failure There are two thermostats: the cycling thermostat located near the thermal fuse on the blower enclosure, and the thermostat located on the heating element.You want the tube to be as straight and direct to the wall as possible. This is especially important if you are using flexible tubing. Crushed Ventilation When sliding your dryer back into place make sure the ventilation that connects from the dryer to the wall is not kinked.Your dryer need good ventilation in order to dry cloths properly and maintain the proper temperature. Clogged Vents You will want to clean out the vents inside the dryer, the ventilation tubing behind the dryer, and the vents running through your house.This is the main reason why fuses brake.The following list are things you will want to check so your fuse does not break again. Thermal fuses are meant to protect your dryer from overheating and damaging your dryer or even worst starting a fire. Reasons why your thermal fuse broke or keeps breaking It is an important device that is meant to prevent the dryer from over heating and prevent fires. *You should never leave the dryer fuse bypassed. If the dryer still not heat the the fuse is good. If the dryer begins to heat then you know the fuse is bad. Step 5: Turn the dryer on, but not for to long. Step 3: Use a wire nut or electrical tape to connect the two fuses directly together. Step 2: Unplug the the wires to the thermal fuse Otherwise, you will want to contact a certified repair technician. It is not recommended to try this method unless you are comfortable. Otherwise it is bad and will need to be replaced. If you get a reading of 0 or a beeping sound then the fuse is good. Step 2: Touch each end of the leads to each of the fuse terminals. Step 1: Set the multi meter to continuity and or resistance. You can find one at your local hardware store or you can order a multi meter using the link. Most multi meters will have this feature and can inexpensive. What You NeedĪll you need is a multi meter that can read continuity and or resistance. Once this fuse is blown it will have to be replaced. Fuse temperature ratings can range from 300 to 350 degrees. This fuse is responsible for making sure the heating element does not go over a certain temperature. If your dryer runs but does not heat your high limit thermal fuse may have blown.
