Frigidaire FRP12PTT2A0 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin an important defrosting cycle which may be needed in order to keep the outdoor unit free from frost build-up. The board is relayed information from a defrost sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Some clues your outdoor defrost sensor board has very little life left
- The main circuit board may show an error of some type if the defrost board goes out
- Your HVAC system will stop functioning due in part to way too much frost build-up
- Defrosting has not run for a while despite the fact that there is a lot of frost on the external unit
