Whirlpool Dryer Thermal Cut-Off Fuse and High-Limit Thermostat Kit 280148

Genuine Whirlpool OEM kit containing a thermal cut-off fuse and high-limit thermostat; the thermostat includes an inlet thermistor. The components protect the dryer from overheating by interrupting heater operation when unsafe temperatures are detected.

Is This the Right Part?

Common Symptoms

• Drum tumbles while the exhaust air remains cold.
• Dryer stops mid-cycle after heating begins.
• Loads require substantially longer than normal to dry.
• A thermal cut-off tests open for continuity when checked with power disconnected.

Check Before Replacing

• Disconnect electrical power before inspecting or testing the components.
• Confirm the dryer has the correct power supply and that the circuit breaker or fuses are not the cause of the no-heat condition.
• Inspect the exhaust hose and vent outlet for lint blockage or restricted airflow, since overheating can cause the thermal cut-off to open.
• With power disconnected, test the thermal cut-off for continuity; an open result indicates the fuse has opened, but does not by itself establish the root cause.
• Inspect wiring connectors around the heater box and thermostat for loose, damaged, or heat-discolored connections.
• Do not bypass, short, or reset the thermal cut-off; it is a safety device.
