OEM Carrier Economizer Control Board Kit HH63AW001 for Model TFACCY48TM482637

This is a genuine OEM Carrier Economizer Control Board Kit (part# HH63AW001), the factory-specified replacement for the Carrier TFACCY48TM482637 packaged rooftop unit. The economizer control board is the command center for your unit's demand-controlled ventilation (DCV) system — it continuously monitors indoor CO₂ levels and outdoor air conditions, modulating the economizer damper to optimize fresh air intake and reduce mechanical cooling load. When this board fails, common symptoms include stuck-open or stuck-closed dampers, DCV fault codes, erratic outdoor air percentages, or a complete economizer lockout that forces the unit into full mechanical cooling at all times.

• Specs: Carrier OEM Part# HH63AW001 | DCV Economizer Control Board Kit | 120V / 60Hz | Cross-reference: W7212A1017 | Dimensions approx. 4" × 4" × 2" | Weight: 1 lb
• OEM vs Generic: This is a genuine Factory Authorized Parts board built to exact Carrier tolerances. OEM boards ensure full compatibility with the unit's communication bus, sensor inputs, and damper actuator outputs — critical for accurate DCV operation and energy code compliance.
• Install Difficulty: 3/5 — Board replacement requires disconnecting low-voltage wiring harnesses and verifying DCV sensor connections. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a laptop or handheld tool to re-configure DCV set points post-installation. Always de-energize the unit at the disconnect before servicing.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
