XPARTCO 280148 Dryer Thermostat Set
2-piece high-limit thermostat/thermistor and thermal cut-off safety kit for select Whirlpool-built electric dryers.
Product Overview
The XPARTCO 280148 Dryer Thermostat Set is a quality aftermarket replacement kit designed for compatible Whirlpool-built dryers. The set combines the heater-box over-temperature controls that help protect the dryer from unsafe heat conditions.
The kit includes one 8318314-style thermal cut-off fuse and one 8557403 / WP8557403-style high-limit thermostat with integrated thermistor sensor.
Quick Answer
280148 is a 2-piece dryer heater safety kit. The thermostat/thermistor assembly is marked L295-80F; the thermistor typically measures about 50–60 kΩ at room temperature. The included 8318314-style thermal cut-off is commonly specified as a 352°F safety fuse. Verify the exact dryer model before ordering.
What's Included
- 1 × Thermal Cut-Off Fuse — replaces 8318314
- 1 × High-Limit Thermostat with Thermistor — replaces 8557403 / WP8557403
Both components mount on or near the heater housing on compatible dryers and work together as part of the dryer's over-temperature protection system.

- Dryer runs but produces no heat
- Heating element shuts off unexpectedly
- Dryer overheats

Installation & Diagnostic Notes
- Disconnect the dryer from electrical power before service.
- Locate the heater housing and confirm the original component numbers before removal.
- Photograph and label the wiring before disconnecting the old components.
- Test the thermal cut-off for continuity and check the thermostat/thermistor against the manufacturer's service specifications.
- Inspect the heating element for grounding or damage and inspect the blower path and exhaust vent for restrictions.
- Install the replacement components in the original mounting positions and reconnect wiring exactly as designed.
- Reassemble the dryer fully before restoring power.
Do not bypass either safety device. A blown thermal cut-off often indicates restricted airflow or another overheating condition. Correct the underlying cause before returning the dryer to service.
