Genuine Coleman Mach OEM replacement return air grille for the 8430A633 and 8430A6332 Deluxe Chill Grille 2 ceiling assemblies. White. Single grille included. 0.4 lbs. 90-day limited manufacturer warranty.
The Coleman Mach 8430-3701 is the factory replacement return air grille for the 8430A633 and 8430A6332 Deluxe Chill Grille 2 ceiling assemblies. These two assemblies are successive production versions of the same lateral ducted, cool-only ceiling assembly — the 8430A6332 being the revised edition of the 8430A633, both sharing the same grille configuration and the same replacement part.
The return air grille is the intake panel on the ceiling assembly — warm interior air passes through it on its way back into the plenum for recirculation through the air conditioner. The Chill Grille 2 features the EZReach filter system: loosen the fastener, swing the grille open, and the washable air filter is immediately accessible without tools. A cracked, warped, or damaged return air grille should be replaced to maintain proper airflow balance through the assembly and protect the filter from bypassed air.
