Thick ice sheet forming on the bottom of the freezer compartment.

Safety first: Unplug the freezer before working inside.

• Step 1 – Remove ice: Chip away loose ice carefully with a plastic scraper and use towels to soak up water.
• Step 2 – Access drain: Remove the rear interior panel to expose the evaporator and drain trough. Locate the drain hole at the center or rear.
• Step 3 – Melt blockage: Use a turkey baster with warm water to flush the drain until water flows freely into the drain pan below.
• Step 4 – Clear tube: From the rear, gently insert a flexible brush or tubing into the drain line to remove any remaining debris.
• Step 5 – Reassemble and monitor: Reinstall panels and monitor for recurrence. If the drain repeatedly freezes, a drain heater kit (if available for your JennAir model) may be needed.
