Is This the Part You Need?
This is the oven door inner glass panel for select LG gas and electric ranges. The inner glass is the pane that faces the oven cavity — it provides thermal insulation, contains heat within the oven, and protects the outer door assembly from radiant heat. When the inner glass cracks or shatters — most often from thermal shock caused by cold water splashing on a hot surface, or from impact — heat escapes through the door, the oven struggles to hold temperature, and the outer door becomes dangerously hot to the touch. This is a structural safety component and should be replaced promptly.
Symptoms / Reasons to Replace
- Cracked, chipped, or shattered oven door inner glass
- Heat escaping from the oven door during operation
- Oven not reaching or holding set temperature efficiently
- Outer door surface excessively hot during use
- Visible damage to the interior glass panel
- Condensation or moisture between the door glass panes

💡 Pro Tip — Replace the Outer Glass & Door Gasket While the Door Is Apart:
If the inner glass cracked from thermal shock, inspect the outer glass and door gasket at the same time — stress fractures in the outer pane are easy to miss until the door is fully disassembled. The door gasket also takes heat damage over time and is a 10-minute replacement while the door is already off. Doing both now saves a second disassembly later.
