Description

This evaporator block is a molded insulation piece that helps direct airflow and limit frost build-up around the evaporator in refrigerator freezers. Replacing a damaged or missing block restores proper airflow paths and helps maintain consistent cooling. What it does:

• Fits around the evaporator to insulate and channel cold air through the correct passages.
• Limits excessive frost accumulation on the evaporator coil by closing unwanted gaps.
• Helps maintain even temperatures in the freezer compartment for reliable cooling.
• Can reduce cycling issues and improve overall fridge performance when original insulation is compromised.

What's included:

• One evaporator insulation block

Install notes:

• Disconnect power to the appliance before servicing to avoid shock.
• Defrost and remove accumulated ice from the evaporator area before installing the new block.
• Remove evaporator cover/panels as needed; handle the block gently to avoid tearing molded foam.
• Reassemble panels and restore power; check for proper airflow and ice/frost levels after a full defrost cycle.
