Suburban SFVHQ Furnace Rear Blower Housing | 521253 | OEM

Restore the rear-half blower housing on your Suburban SF/SFV VHQ/VHFQ furnace with the Suburban Furnace Blower Housing — Rear Half (Part #521253). Genuine Suburban OEM rear-half blower housing — broad compatibility across the SFVHQ/SFVHFQ furnace lineup and matching SFV-Q/SFV-F variants, from SF-20VHQ up to SF-42VHQ.

What This Does

The rear-half blower housing is the structural enclosure around the rear side of the furnace blower assembly. Replaces damaged, cracked, or corroded original housings — restores proper airflow direction and blower protection.
