Whirlpool Microwave Thermostat W10840013

Is This the Right Part?

Common Symptoms

• Microwave stops heating mid-cycle and will not restart
• Microwave runs (turntable spins, light on) but produces no heat
• Microwave shuts off after a short time and feels excessively hot
• Microwave trips the internal thermal cutout repeatedly

Check Before Replacing

• Test the existing thermostat for continuity — a failed-open thermostat reads no continuity at room temperature
• Inspect the door switches — a faulty door switch can mimic a thermostat failure and prevent heating
• Check the magnetron and high-voltage diode — these can fail independently and produce identical no-heat symptoms
• Verify the vent fan and filters are clear — blocked airflow causes repeated thermal cutout trips without a faulty thermostat
