Product Description

The CARRIER 45mbcq02xxx4 is a replacement cassette grille panel designed for the 45MBCAQ series ductless mini-split indoor units running on R454B refrigerant. This panel serves as the decorative and functional face of the ceiling cassette, housing the return air grille and directional louver assembly. It is installed on the visible underside of the cassette unit and must be correctly seated to ensure proper airflow distribution across the conditioned space. Sized at 40.75 inches by 40.75 inches with a profile depth of 3.54 inches, this panel is a direct OEM-style replacement part sourced through Factory Authorized Parts. Licensed HVAC technicians performing maintenance, replacement, or commissioning on compatible cassette systems will typically handle this component.

This grille panel is suited for ceiling cassette mini-split installations in both residential and light commercial applications. It is specifically matched to CARRIER 45MBCAQ series indoor cassette units in the 24,000 to 48,000 BTU/h capacity range that operate on R454B refrigerant. Common install scenarios include drop-ceiling commercial spaces, open-plan residential areas, and multi-zone systems where a flush ceiling-mount cassette is the preferred indoor unit style.
