Oven glass window is fogged, streaked between panes, or shows condensation that does not wipe off.

Safety first: Allow the oven and door to cool completely. Glass edges can be sharp; wear gloves.

• Check door seal: Inspect the door gasket and hinges to ensure the door closes tightly, minimizing moisture entry.
• Drying cycle: Sometimes extended high‑temperature operation can dry out minor condensation. Run the oven at 400°F for 30–45 minutes with good ventilation and see if the fogging improves.
• Door disassembly (advanced): If moisture remains, the door may need to be disassembled to clean or replace the glass pack. This involves removing screws around the door perimeter and carefully separating the inner and outer panels.
• Replace glass assembly: For persistent or severe fogging, replace the BlueStar oven door glass assembly or inner glass with new seals.
