Removed three screws securing the bottom microwave panel. Replaced both the socket and bulb. The process was simple and quick. I did the initial troubleshooting, then ordered the parts. Upon arrival, the installation was super simple, however the initial part, i.e. diagnosing and getting to the defective parts took about an hour as I was not familiar with the process. All in all a simple task.. The parts were inexpensive and the Appliance Parts Pros website was easy to navigate. Seamless experience. Kudos to Appliance Parts Pros.com.
