Common Symptoms
- Microwave or oven stops after running for a short time
- Microwave does not heat or heats inconsistently
- Cooling/exhaust fan does not operate when temperature rises
- Overheating or thermal-protection interruption
- Oven heating is insufficient or uneven
Check Before Replacing
- Confirm the appliance model number and verify that W11568584 is specified for that model before testing or replacing the part.
- Disconnect electrical power before accessing the thermostat.
- Visually inspect the thermostat, wiring, and terminals for looseness, discoloration, or heat damage without bypassing or jumping the safety device.
- With power disconnected, a qualified technician may check thermostat continuity according to the appliance-specific service documentation; lack of expected continuity can indicate an open thermostat, but other faults can produce the same symptom.
- For microwave installations, do not access internal components unless qualified, because high-voltage capacitors may retain a dangerous charge even after unplugging.
Pro Tip
Because this is a safety thermostat, do not bypass it or assume a no-heat symptom proves the thermostat is defective; verify the model-specific wiring and test procedure first, and investigate the underlying overheating cause if it has opened.
