Carrier 342970-75103 Door Kit

The Carrier 342970-75103 is a filter door assembly kit. The door closes the filter rack opening on the cabinet and seals the return-air path, so the blower draws air through the filter rather than around it. This is a genuine Carrier replacement part.

Confirm that the part number on your existing door, or in your unit's parts list, reads 342970-75103 before ordering, since door dimensions differ between cabinet sizes. Shipping weight is 11 lbs.
