The MIDEA 12120600000440 is a sliding filler panel designed to seal the open gap on either side of a window-mounted room air conditioner installation. Measuring 24 inches in length by 4 inches in height, this accordion-style or rigid slider panel closes off the space between the AC chassis and the window frame, blocking outdoor air, insects, and moisture from entering the conditioned space. It is a direct replacement accessory for Midea room air conditioning units and is typically installed by HVAC technicians or experienced DIYers during initial unit setup or when the original panel is lost or damaged.
This filler panel is suited for residential window AC installations where a 24-inch by 4-inch gap closure is required. It fits into the side tracks of compatible Midea window air conditioner units and is used in single or double-hung window applications. Because it is a Midea-branded accessory, it is intended for use with Midea room air conditioners that accept a slider panel of this specific dimension.
Designed as an OEM-style replacement slider panel for compatible Midea room window air conditioner units that accept a 24-inch by 4-inch side filler panel.
Installation should be performed with the air conditioner unit powered off and unplugged before handling any panels or accessories. The panel slides into the designated side track channels on the AC chassis and window frame assembly. No special tools are typically required, but verify the panel seats fully and securely before restoring power to the unit. Follow local building and energy codes when sealing window AC installations.
