Whirlpool Microwave: not responding to button presses

Professional Repair Guide

What is this symptom?

If your Whirlpool microwave powers on but the buttons and touch controls are unresponsive, it can be frustrating. The display may light up, yet pressing any button yields no results. This issue can arise from several causes, including a control lock feature being engaged or a temporary glitch in the control board.
