International Comfort Products PGAA30D1K6 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost sequence which actually helps to rid your unit of frost that can build up. It relies on a specific sensor which is near the condenser somewhere, in order to determine when the defrost cycle should begin.
Important hints your outdoor defrost sensor board will eventually need to be replaced
- Your main control board might issue an error of some type when encountering a problem
- Self defrost sequence never kicks in especially when there is frost on the unit
- Your system could end up not running due in part to the frost blocking the flow of air
