What happens when thermal fuse blown on dryer?

At room temperature, the thermostat should give off a continuity reading of zero, so touch one probe to one terminal and the other probe to the other terminal and check the tester’s display. It should read zero. If it reads infinity, then the thermostat is bad.

What happens when thermal fuse blown on dryer?

Test the high limit thermostat. Touch one of the multimeter probes to the left terminal and the other probe to the right terminal at room temperature. If the instrument shows zero ohms of resistance, the electrical path between the two terminals is open and the thermostat is working properly.

Are all dryer thermal fuses the same?

All dryers sold in the United States are legally required to have a thermal fuse. This is different from the electrical fuses that are found in many appliances, and a dryer might have both. A thermal fuse will blow when the temperature gets too high, not when it’s drawing too much current.

How do I test my thermostat?

How long should a clothes dryer last?

eight to 12 years

How does a thermal fuse work?

A thermal fuse is a cutoff which uses a one-time fusible link. Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature and not to excessive current (unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature).

How do I test my thermostat?

You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermal fuse should produce a reading of zero. But if a thermal fuse is tested when it is heated to its limit, a reading of infinity should be produced.

Why is the dryer blowing cold air?

The cycling thermostat normally controls the on and off of the heating element. If the cycling thermostat is stuck in the open position, the dryer blows cold air. In some cases, the high-limit thermostat is a thermal fuse; if this thermal fuse has burned open, the dryer blows cold air.
