Estate gas dryer where is thermal fuse

The number one cause of thermal fuses blowing is the build-up of lint inside the exhaust venting which makes the dryer overheat. At least once a year you should detach the venting from the rear of the appliance and use a vent brush to clean out the lint and any other debris to ensure good air flow. In addition to fuses, Repair Clinic carries all the replaceable appliance parts to fix your dryer such as igniters , gas valve solenoids , heating elements , thermostats , timers , door switches , and much more.

Will the dryer run if the thermal fuse is blown? If the meter display shows zero Ohms of resistance, the fuse has electrical continuity and has not blown, indicating that another component in the dryer is likely defective and preventing the appliance from running or heating.

If the meter display shows no significant change, the fuse has no continuity which means it has blown and will need to be replaced. Shop Dryer Thermal Fuse Parts. Ensure to shut off electrical power to the dryer before attempting to locate and troubleshoot the fuse. Most dryers plug into a volt wall outlet, so you can unplug the unit to cut off power. Thermal fuse shapes and sizes vary. Some are made from plastic; others are metal. Look for a small device about the size of a quarter to about 2 inches long, mounted directly on top of the exhaust duct.

A thermal fuse has two wires connected to it. A reliable method for testing whether a thermal fuse has burned out is to temporarily bypass the device.

However, it is tempting to operate the dryer this way, or forget to replace the fuse once the dryer is running. Bypassing the fuse is only a quick means of detecting whether the fuse is bad. It is not a permanent fix. Disconnect the two wires from the fuse and tie them together with a jumper wire, then turn on the dryer. If it runs and heats, the thermal fuse burned out and must be replaced.

A better, faster means of testing requires an electrical multitester set at its lowest RX setting. Remove the two wire leads from the thermal fuse and touch a multitester probe to each wire terminal on the fuse. If you get a reading of infinity, the fuse is fine. Any reading less than infinity indicates a triggered thermal fuse you will need to replace. Replace the fuse with an exact match for your dryer make and model.

Then check the dryer for a reason why the fuse burned out. Sometimes, age wears out a fuse, but other times something else failed and caused exhaust temperatures to rise. Ensure the power is still off before troubleshooting, then examine the exhaust duct for obstructions that limited air flow.
