When you disassemble your unit to access the components, the slender thermal fuse is usually towards your left on the blower assembly. Some readers may not be familiar with thermal fuses and thermistors, especially when they are next to one another on Duet dryers. Unlike a fuse that won’t let the heating element or burner start, a failing thermistor will shut the dryer prematurely by erroneously detecting a massive temperature spike (i.e., overheating). An electric variant has another next to the heating element.Ī bad thermistor prevents a Duet Whirlpool dryer from heating or reaching a high temperature. If you have a gas Duet Whirlpool dryer, there’s only one thermistor on the blower assembly. This sensor isn’t exactly a thermal fuse it’s more of a thermostat. Whirlpool Duet dryers have a thermistor regulating the heating cycle. While the thermal fuse on Duet Whirlpool dryers isn’t unique, you must try to get a manufacturer-approved replacement. You’ll find the part number on the thermal fuse match it when you buy a replacement. If one or both fuses have continuity, test the adjacent thermistor.Replace the fuse if it has no continuity and nil or infinite resistance.You may also set the multimeter to least resistance to test the same.Test the thermal fuse terminals for continuity with a multimeter.Remove the wire harnesses of one or both fuses (subject to the model).Take a picture of the wiring so you can reassemble it accordingly once you’re done.Find the thermal fuse(s) ー Duet gas dryers only have one thermal fuse on the blower assembly, while electric dryers have a second one on the heating element assembly.Locate the blower and heating assemblies at the bottom.
#WHIRLPOOL DUET DRYER THERMAL FUSE DRIVER#
Get a 1/4 inch socket or nut driver to take out the screws.Remove the kick plate or front panel (subject to the model).Unplug the Whirlpool Duet dryer (gas or electric).Test the thermal fuse and replace it if it has no continuity.
So, you must also address those issues to prevent a new thermal fuse from blowing. This outcome could be due to a failed part (as in the fuse itself) or other factors causing your dryer to overheat and blow its fuse. I must mention here that a blown thermal fuse is a consequence. Also, it is easy to test whether the thermal fuse is broken or not. Fortunately, this tiny yet critical part is an inexpensive problem to fix. The thermal fuse is among the likeliest culprits if you suddenly find your dryer not heating one day. Regardless of the number, your Duet Whirlpool dryer won’t heat if you have a blown thermal fuse. Electric dryers have two thermal fuses, whereas the gas Duet models have only one. The thermal fuse is a safety fixture in both gas and electric dryers in the Whirlpool Duet series.
