If you do not have a multimeter, you can also test whether or not the fuse is working by bypassing the fuse itself. First, i must assume that you have 220 volts of electricity supplied to the dryer.

In addition, the dryer may have a thermometer and temperature control or a simple thermostat. You can find the parts breakdown for many models online; When the fuse blows it can cause the dryer to run but not heat, or to not run at all.

So there are three temperature sensors in most dryers, and the thermal fuse is the last. Let it cool if it’s hot. Any of these could result in the overheating of your dryer which leads to a thermal fuse that will blow.

If your dryer is slowly losing heat, this would be a sign of your heating element going bad, not your thermal fuse. It will be inside the back cover panel. Remove the two wire leads from the thermal fuse and touch a multitester probe to each wire terminal on the fuse.

What it does, how to test it, where to find it. Install the new thermal fuse in the reverse order that you removed the old one. It should be tested across the two outside terminals at.

The leading cause of thermal fuse burnout is obstructed airflow. Many models have a thermal fuse mounted on the exhaust duct. If you have a bad thermal fuse, make sure address why the dryer was overheating.

If the thermal fuse is expensive or hard to get, then substitute a temporary fuse of the same rating just to test with before replacing the oem fuse. If the thermal fuse is not allowing any current to pass, the clothes dryer will not heat. At this point, you should purchase a replacement thermal fuse.

Check to see whether it. So be sure you discover what caused the fuse to fail. Disconnect the wires from the thermal fuse by gently pulling on them.
