Their thermal fuses will fuse and separate the power circuits. This automatic readjustment occurs when devices exceed their usual temperatures. In addition, thermal fuses automatically fuse to disrupt the power supply and prevent fire outbreaks from electrical appliances. Thermal fuses ensure that these appliances do not overheat. Thermal fuses are so significant in appliances like dryers and coffee makers where a mere malfunction could cause the internal temperature to increase rapidly. Essentially, devices that produce heat need thermal fuses. Thermal fuses prevent excess heating by opening up circuits when unfavorable events occur. Like fuses assist in the smooth operation of electronics and electrical systems, thermal fuses are safety devices that identify heat rise from overcurrent or surge within an electric system. If you have a blown thermal fuse, replace it as soon as possible! Are Thermal Fuses Necessary? You’ll only be putting your dryer at a high risk of devastating damages like fire outbreaks, which could further affect your entire home. You can bypass a thermal fuse on your dryer however, it is something that I don’t advise. They often want to know if they can Bye-pass the thermal fuse on their dryers. Surprisingly, a short power outage can cause your thermal fuse to blow- this usually occurs when the electricity comes back on.ĭue to cases like blown thermal fuses, most homeowners are generally curious about bypassing thermal fuses. $50-$75 once every 4-5 years is worth it in my book.Dryers play a vital role in helping us do our laundry and domestics without using outside sources like the sun.īut, unfortunately, things can go wrong the most common problem with dryers is the thermal fuse. I keep a spare set of the thermostats and fuses on hand. FYI – you may as well do a thorough cleaning of lint from the dryer and the dryer vent at this time and have the peace of mind. In short, as long as you have the dryer a part you may as well just replace the Thermal cut-out kit, the High Limit Thermostat and the Cycling Thermostat.Īs a DIY job it will be cheaper than a service call. If the thermal cut-off fuse is bad, it’s because the high-limit thermostat is bad (not cutting out at high temps). They have a cycling thermostat and a thermo-cutout kit consisting of a high-limit thermostat and a thermal cut-off fuse. Whirlpool Gas dyers and all gas dryers made by Whirlpool all have the same design. You literally have to somehow raise the temp to it’s cut-out temp and then check continuity. If you check then for continuity at room temperature, you will not know if they are bad.

You have to check the thermostats for continuity at their cutout temperature which can be up to 265 degrees in the case of the high limit thermostat. In my experience, (gas dryer) there are two reasons the thermal fuse will blow.ġ) Blocked vent causing the dryer to overheat.Ģ) Thermostats failing to cut out at correct temperature – and again causing the dryer to overheat.

What brand machine do you have and what was causing the problem? Comment now and let us know. Have you had issues with a thermal fuse tripping? The simple fact is, it doesn’t happen for no reason at all. In the end, anytime the thermal fuse or cutoff trips, it will need to be replaced.Īs a one-time use part, it’s not designed to be reset.Īlso, remember to track down the actual problem when this fuse blows.

Plug the dryer in and test to see if it’s working properly.

Position the new heating element to the heater box properly and screw into place.

Remove the high-heat thermostat from the old heating element and transfer it to the new one.

Mark the location of each wire, so you can remember where they go later.

The heating element will be located near the bottom of the machine, you’ll need to disconnect the wires going to it.

To repair this problem you will need to follow these steps: When this occurs it will cause your dryer’s heating element to remain “ON” constantly, even during the fluff or AIR ONLY cycle.Ĭycling thermostat just not able to control amount of heat produced by the heating element.Įventually, this will cause your dryer to overheat which will trip the thermal cutoff fuse.

When the coils in the heating element expanding, they can touch metal casing and it can cause the heating element to become grounded.
