OEM Carrier Economizer Control Board Kit HH63AW001 for Model TCHC1850HE401481

This OEM economizer control board kit (part number HH63AW001) is the factory-specified replacement for the Carrier TCHC1850HE401481 packaged rooftop unit. The economizer control board manages the motorized outdoor air damper system, regulating the ratio of fresh outside air to return air based on enthalpy or dry-bulb temperature inputs. When this board fails, the economizer damper may stick open or closed, trigger fault codes, cause the unit to lock out, or result in poor indoor air quality and uncontrolled energy usage — all symptoms that point directly to board-level failure.

• Specs: OEM Carrier economizer control board kit | Part No. HH63AW001 | 24V control circuit compatible | Designed for use with integrated economizer damper actuators on packaged rooftop systems
• OEM vs Generic: This is a genuine OEM Carrier board, factory-programmed to the exact control logic required by the TCHC1850HE401481. Aftermarket boards frequently lack proper fault-code sequencing and enthalpy sensor compatibility, risking damper miscalibration and equipment damage.
• Install Difficulty: 4/5 — Economizer board replacement requires disconnecting low-voltage control wiring, enthalpy or dry-bulb sensor leads, and actuator connections. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, wiring diagram (attached to unit access panel). Recommended for qualified HVAC-R technicians only.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.
