Joseph C Wayne , NJ April 11, 2015 Some buttons on touch panel of microwave were non functioning Ordered exact replacement part from AppliancePartsPros.com. Removed door, vent panel and touch panel from my under-the-counter microwave, removed circuit board from old touch panel, installed on new touch panel and reinstalled everything on microwave. Only difficulty was attaching two of the screws for the circuit board -the plastic mounting holes seemed undersized/screw was binding and could not be tightened flush. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
