Description

This oven back insulation replaces the rear cavity insulation to help contain heat and improve oven performance. It fits behind the oven liner and restores proper thermal protection for safe, efficient operation. What it does:

• Replaces damaged or missing rear oven insulation that can allow heat loss.
• Helps reduce heat transfer to surrounding cabinetry and components.
• Can improve temperature stability and reduce uneven cooking when insulation is compromised.
• Helps limit hot spots and reduce abnormal smells from overheated cabinet areas.

What's included:

• One oven back insulation panel (1 piece).

Install notes:

• Disconnect power at the breaker and allow the appliance to cool completely before service.
• Access typically requires removal of the oven's rear access panel or slide-in range rear cover—keep fasteners in a safe place.
• Wear gloves and eye protection; handle insulation carefully to avoid tearing or compressing the material.
• Reinstall panels and fasteners securely; test oven heating after reassembly.
