Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Little or no heating
• Uneven or inconsistent heating
• Failure to start or unexpected shutdown when the inverter circuit is involved

Check Before Replacing

• Confirm the microwave is receiving power and that the selected cooking cycle is operating normally.
• Verify the symptom with a suitable container of water, without operating the microwave empty.
• Inspect the accessible power cord and, only with the appliance unplugged, check for visibly loose or damaged external connections.
• Use the appliance’s model-specific tech sheet for any inverter diagnostic procedure; do not remove the microwave cabinet or take voltage measurements unless performed by a qualified appliance technician because lethal high-voltage charge may remain after unplugging.
• Do not conclude that the inverter board is defective from a no-heat symptom alone; the magnetron, wiring, controls, and other high-voltage components can produce similar symptoms.
