Paul B Seminole , FL August 21, 2015 Outer glass shattered on kenmore oven for no apparent reason Got the replacement from AppliancePartsPros.com. It was cheaper than other sites including shipping. The part arrived within 2 days. After watching some videos suggested by other APP customers, the fix was easy. Will use APP whenever necessary.
