OEM Carrier Integrated Control Board CESO130076-00 for Model PH3ZNA024000AA

This OEM integrated function control (IFC) board is the factory-specified replacement for the Carrier PH3ZNA024000AA packaged heat unit. The control board serves as the central nervous system of your HVAC system — orchestrating ignition sequencing, blower motor timing, fault detection, and communication between all major components. Common failure symptoms include a system that won't heat, repeated lockout codes, erratic blower behavior, or a unit that powers on but fails to initiate a heating cycle.

• Specs: OEM Part Number CESO130076-00 | Factory-matched firmware and relay configuration | 24V control circuit compatible | Plug-and-play connector harness alignment
• OEM vs Generic: This is a genuine OEM Carrier board programmed to exact factory specifications. Aftermarket control boards frequently carry mismatched timing delays and relay ratings that can cause premature component failure, nuisance lockouts, or void existing equipment warranties.
• Install Difficulty: 3/5 — Requires disconnecting 120V/240V line voltage before servicing. Tools needed: ¼" nut driver, Phillips screwdriver, needle-nose pliers, and a smartphone to photograph all harness connections before removal. Always power down and verify zero voltage at the board before handling. Professional installation recommended.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our climate-controlled warehouse.
