Patricia C Tampa , FL November 22, 2016 Microwave exterior lights were out Purchased 20 watt halogen push in bulbs to replace old ones. It was very easy, just had to screw back in the glass cover after pushing the bulbs in. Bulbs were delivered the next day after purchase from ApllancePartsPro.com, awesome service! 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
