Frigidaire Dryer Thermal Limiter Parts — Models & Compatibility

If your Frigidaire dryer won't start, runs but doesn't heat, or gets dangerously hot, the thermal limiter (also called a thermal fuse) is likely blown. This safety component cuts power when internal temperatures exceed safe limits — and once it trips, it doesn't reset. You'll need to replace it. The 134120900 thermal limiter fits over 100 Frigidaire, Electrolux, and Kenmore dryer models across multiple series.

Is This the Right Part for Your Model?

Check your dryer's model number before ordering. You'll find it on a metal tag inside the door frame or on the back panel near the power cord. This thermal limiter replaces part numbers AP2108182, PS419402, 5303209192, and 1489053. It's compatible with AEQ, AEQB, ATF, CFLE, CFSQ, FAFS, FEQ, FQG, GLEF, and many other Frigidaire-manufactured series.

About This Replacement Part

The thermal limiter is a one-time-use safety device mounted on the dryer's heating element housing or blower housing. When lint buildup restricts airflow or the heating element cycles improperly, exhaust temperatures spike. The thermal fuse detects this and breaks the circuit to prevent fire. Common symptoms of a blown thermal limiter include a dryer that tumbles but produces no heat, one that won't start at all (on some models the fuse protects the motor circuit), or a unit that overheats clothes and shuts off mid-cycle. Unlike a cycling thermostat, the thermal limiter doesn't reset — once it blows, you're replacing it.

Before you install the new fuse, figure out why the old one failed. Check the exhaust vent for restrictions, clean the lint screen housing thoroughly, and inspect the blower wheel for lint buildup. If you just swap the fuse without addressing airflow problems, the new one will blow too.

What Causes Thermal Limiters to Fail?

Thermal limiters blow for three main reasons: blocked exhaust vents, clogged lint screens or housing, and failed cycling thermostats. A crushed or kinked vent hose traps hot air inside the drum. Lint packed into the blower wheel or around the heating element housing creates hot spots. And when the cycling thermostat sticks closed, the heating element runs continuously until the thermal limiter trips. You'll also see premature failures on dryers installed in tight spaces with poor ventilation or vented through excessively long duct runs.

Installation Overview

Replacing the thermal limiter typically takes 30 to 45 minutes. You'll unplug the dryer, remove the top or front panel (depends on your model design), locate the fuse on the heating element housing or blower housing, disconnect the wire leads, and install the new fuse. Use a continuity tester to verify the old fuse is indeed blown before you order the part — no continuity means it's open. Once the new fuse is in, reassemble the dryer, clear the vent system, and test a cycle.
