• Compatible brand: Samsung
• Appliance type: Over-the-range and countertop microwave

• IMPORTANT: Microwaves store lethal high-voltage charge in the capacitor even when unplugged. Always discharge the capacitor before servicing. If you are not experienced with microwave repair, hire a qualified technician.

• Unplug the microwave and discharge the high-voltage capacitor before touching any internal components — the capacitor can hold a lethal charge even after unplugging
• Remove the outer cabinet to access the thermostat — typically located near the magnetron or on the cavity wall
• Before replacing, check whether the existing thermostat has simply tripped (some are resettable) — test with a multimeter for continuity
• If the thermostat has failed open (no continuity), replace it
• Note the wire terminal orientation before disconnecting
• Ensure the new thermostat makes firm contact with the mounting surface for accurate temperature sensing
• Investigate and resolve the root cause of overheating (blocked vents, failed fan) before returning the microwave to service
