When the touch control buttons on a Whirlpool microwave completely stop responding, you can follow a structured troubleshooting process to resolve the failure. First, check if the child safety lock feature is accidentally engaged, and disable it by pressing and holding the designated lock button for three seconds. Second, perform a hard power reset by unplugging the microwave from the wall outlet for two full minutes to clear internal logic freezes. Third, inspect the ribbon cable connecting the keypad to the control board. You can troubleshoot control panel lockups safely. You can verify that your corrective action is successful when resetting power, deactivating the child lock, or replacing a faulty touch membrane restores normal button responsiveness across the entire keypad.
