International Comfort Products PGAA24C1K1 Defrost Sensor Board
The defrost sensor board will begin an important defrosting cycle if necessary, to continue normal heating and cooling operations. The control board depends on a specific sensor that can be found near the condenser, in order to determine when to begin.
Chief elements of an inadequate AC defrost sensor board
- The main control board might issue an error number if the defrost board goes out
- Self defrost sequence does not run even though there is a large amount of frost on the outdoor unit
- Air conditioning may stop running due in part to the frost blocking the flow of air
