Friedrich 67401406 Main Pcb Control Board

Product Description

The FRIEDRICH 67401406 is a main printed circuit board (PCB) designed as a direct OEM replacement control board for compatible Friedrich wall air conditioning units. The main PCB serves as the central control hub of the cooling system, managing compressor operation, fan speed, thermostat input, and overall unit functionality. This board is sold as an individual unit and is intended for installation by qualified HVAC technicians performing component-level repairs on Friedrich wall-mount air conditioners.

This main PCB is specified for use with Friedrich wall air conditioning systems in residential and light-commercial applications. It is suited for situations where the existing control board has failed, resulting in loss of unit response, erratic operation, or complete shutdown. Replacing the PCB at the component level avoids the cost of full unit replacement and restores original functionality when properly installed.

Installation Notes

Installation should be performed by a licensed HVAC technician. Always disconnect and lock out all electrical power to the unit before removing or handling any PCB components.
