Description
The Lennox Y8437 Outdoor Control Board is an electronic control component used in outdoor condenser units to coordinate cooling operation and control communication in HVAC systems. It is based on the concept of getting signals through thermostats, temperature sensors, and safety switches, processing them through circuit pathways, and the control configuration 17122000A19508 in the board to control the work of the condensers and the sequence of components. It is mounted in the outside unit’s electrical compartment and is interconnected with wiring harnesses, relays, and fan or compressor circuits.
