Customer Questions and Answers for Glass, Inner by Whirlpool

The Inner Glass is an OEM replacement part for Whirlpool built-in and slide-in electric ranges. As an interior part, this tempered glass serves as the viewing window for the oven cavity below. It is precision cut by Whirlpool to fit seamlessly within the oven door frame assembly.

Causes of broken inner glass can include impact from heavy pots or pans dropped inside during loading/unloading. Thermal stresses from repeated heating cycles may develop fine hairline cracks as well. 

Symptoms of a cracked inner glass involve: 

• Visible lines or damaged areas that obstruct full viewing
• Potential safety hazards if glass fully separates from the doorframe
• Inability to efficiently view food inside without opening the door

Compatible with some KitchenAid and Jenn-Air built-in electric ranges too, replacing now prevents further door damage from glass shifting out of position over time.
