Information About 17122300001076
The 17122300001076 is a Carrier-associated outdoor main control board reference used across compatible multizone inverter heating and cooling equipment. The board operates in 208–230-volt alternating-current systems and incorporates dedicated connections for line power, temperature sensors, the four-way reversing valve, heaters, electronic expansion valve, indoor-unit communication, test equipment, and the intelligent power module. It is documented as the printed circuit board reference for replacement control-board assemblies used with Carrier models including 38MGRQ18B--3 and 38MGRQ24C--3, although the complete service-board ordering number can differ by equipment configuration. The control architecture includes a main processor, electrically erasable programmable read-only memory, digital diagnostic display, check button, and low-voltage communication interfaces for coordinating inverter outdoor-unit operation.
Key Features:
- Main Outdoor Control: Coordinates multiple electrical and electronic functions within compatible Carrier inverter outdoor heating and cooling equipment.
- 208–230-Volt Application: The board architecture is designed for outdoor equipment operating from approximately 208–230 volts alternating current.
- Indoor Unit Communication: Includes a dedicated communication connection for exchanging operating information with the connected indoor equipment.
- Electronic Expansion Valve Control: Provides a dedicated output connection for operation of the refrigerant circuit electronic expansion valve.
- Temperature Sensor Inputs: Interfaces with outdoor ambient, condenser, and discharge-temperature sensing circuits used for system monitoring and protection.
- Heater Management: Provides switched outputs for compatible compressor and chassis heaters used by the outdoor refrigeration system.
- Reversing Valve Output: Includes a controlled 230-volt alternating-current output for the four-way reversing valve used to change operating mode.
- Inverter Module Communication: Communicates with the intelligent power module through dedicated low-voltage connections to coordinate inverter-system operation.
The 17122300001076 delivers the reliability and precision required for outdoor-unit sequencing, refrigerant control, temperature monitoring, and inverter system coordination in compatible Carrier heating and cooling equipment.
