This drip tray is the replacement pan that collects defrost and condensate water beneath the refrigerator, helping keep floor and cabinet areas dry. It restores the appliance's normal water drainage path. What it does:

• Catches defrost and condensate water from the freezer/refrigerator evaporator
• Directs collected water to the evaporator/heat source or drain area to allow evaporation
• Helps stop water pooling under or around the appliance that can cause floor damage
• Fits into the cabinet under the unit and works with existing drain and mounting features

• One drip tray

• Disconnect power to the appliance before attempting any service
• Pull the appliance away from the wall and remove the kick plate or front access panel as needed to access the tray
• Replace the tray in the cabinet, ensuring it seats and aligns with existing clips, slots, or drain tube
• If you see additional damage (cracked supports, clogged drain tube), inspect and replace those parts separately

This fan assembly moves air through the appliance to help maintain proper cooling and airflow. It replaces a worn or noisy fan to restore efficient air circulation and temperature consistency. What it does:
