Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Microwave may not start a cook cycle.
• Selected time, power, or cooking-function inputs may not be accepted or may not control operation as expected.

Check Before Replacing

• Check whether the household fuse has blown or the circuit breaker has tripped; reset/replace as applicable. If the condition continues, use a qualified electrician.
• Firmly close the microwave door, then retry operation.
• Confirm the electronic control is set correctly and that Control Lock is not enabled.
• Using a microwave-safe cup with 1 cup (250 mL) of cold water, run a 2-minute test at 100% power as directed in the model troubleshooting guide. If it still will not operate, seek service.
• If the display shows a letter followed by a number and the message returns after clearing, seek service rather than assuming the control assembly is the cause.

Pro Tip

Part Details

Installation Notes

• This is an interior electronic control component; internal microwave repairs should be handled by a qualified appliance service technician after external troubleshooting checks are exhausted.
• Confirm the appliance model accepts WPW10443063 before installation; the official OEM listing provides a model fit check.
• Do not treat a no-start condition as proof that this assembly has failed, because door closure, Control Lock, household power, and other faults can produce similar symptoms.
