OEM Carrier Fan Blower Control Board R99G004 for Model OBMAAB060154AABG

This is the factory OEM fan blower control board (part number R99G004), the direct replacement for Carrier OBMAAB060154AABG air handlers and blower systems. The integrated fan control (IFC) board orchestrates every stage of blower operation — managing motor speed sequencing, heat/cool delays, fault detection, and system lockout logic. When this board fails, you may experience a blower that won't start, a unit stuck in continuous fan mode, erratic speed behavior, or a system that flashes diagnostic fault codes and shuts down entirely. Replacing it with the correct OEM board restores factory-programmed logic and timing sequences that generic substitutes often cannot replicate.

• Specs: OEM Part No. R99G004 | Factory-matched for Carrier OBMAAB060154AABG | 120V/240V input | 24V control circuit compatible | Pre-programmed with factory blower delay and fault logic
• OEM vs Generic: This is the genuine Carrier OEM board — not an aftermarket substitute. Generic boards frequently omit model-specific timing profiles and fault code support, leading to repeat failures, improper motor sequencing, and voided equipment warranties.
• Install Difficulty: 3/5 — Shut off power at the disconnect and breaker before beginning. Tools needed: Phillips and flathead screwdrivers, 1/4" nut driver, needle-nose pliers, and a smartphone to photograph all wire connections before removal. Label every connector. Improper reconnection can damage the new board immediately upon power-up.
• Warranty: 1-year OEM factory warranty against defects. Orders placed by 3 PM local time ship same business day from our climate-controlled parts warehouse.
