Why does my dryer keep burning thermal fuses?

Clogged or restricted exhaust vent air flow is the most frequent cause of a thermal fuse blowing. Check the lint screen for lint or a build-up of debris that could be inhibiting air flow through the dryer. Check the flexible vent hose behind the dryer for kinks or clogs.

What causes dryer thermostat failure?

Blown Thermal Fuse A frayed wire can cause a thermostat to keep going bad. A dryer will blow a thermal fuse if it’s close to overheating. Each time the thermal fuse blows it can interfere with a thermostat’s function and cause it to go bad, too.

Can a dryer thermal fuse be reset?

If you’re wondering how to reset a thermal fuse because your clothes dryer overheated, you’re on the right track, but a thermal fuse — as opposed to a thermal switch — is not resettable, and if one blows and the appliance stops heating or won’t work at all, you have to replace it like you do an old-style electrical …

How can you tell if a thermal fuse is bad?

How to tell if a thermal fuse has blown? To test if your thermal fuse has blown, touch the right side of your multimeter lead to the right side of the fuse, and repeat with the left multimeter lead. If the multimeter needle fails to move, this indicates the thermal fuse has blown.

What are the symptoms of a bad dryer thermostat?

Symptoms of a bad dryer thermistor include air in the dryer that won’t heat up. If the dryer does heat up, a bad dryer thermostat can result in loss of temperature control. If you have a faulty dryer thermostat, the dryer may keep the heat on for too long, causing the dryer to get too hot.

How can you tell if a thermal fuse is blown?

Touch the left multimeter lead to the left side of the thermal fuse; touch the right multimeter lead to the right side of the fuse. Keep an eye on the multimeter needle; a needle that fails to move indicates a blown thermal fuse. If this is the case, don’t fret: thermal fuse replacement is a simple task.

How do you know if your dryer thermal fuse is bad?

Multimeter Test 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.

What causes the thermal cutoff to keep going bad on a dryer?

When a thermal fuse blows on a gas or even electric dryer the most likely cause is a restricted vent. The thermal fuse blowing is related to air flow and temperature. The air flow can be restricted by a bad vent, clogged lint screen or an overloaded drum.

What causes clothes dryer to stop heating?

The most common causes for an electric or gas dryer to stop drying or heating is: 1. The dryer lint screen (lint trap) has not been cleaned (poor or restricted airflow). 2. A clogged or kinked (bent) dryer air vent hose (inadequate or no airflow). 3. Drum has stopped turning, broken drum drive belt.

Why does the dryer fuse keep blowing?

Lint can bypass the trap sometimes, and end up in the wrong places inside your dryer. Once such place it can end up is wrapped around the thermal fuse inside the blower wheel. When this occurs, it will cause the fuse to overheat and blow due to heat build-up.

What causes dryer vent fires?

A clogged exhaust vent is another common cause of dryer fires. When the exhaust duct becomes clogged – whether it’s from lint, dryer sheets or even articles of clothing – it prevents the hot air from escaping, allowing potentially dangerous buildups of gases. Clothes dryers must have an open, functional tunnel to exhaust the hot air.
