SPT TN-09E Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrosting phase which actually helps to remove frost build-up that may accumulate. The board depends on a specific sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
What warnings are present when my outdoor defrost sensor board is about to stop working?
- The main control board could display an error of some type referring to a failing defrost control board
- Defrost session never runs especially when there is a rather large amount of frost that makes the unit run like crap
- AC and heating system could not run for the fact of the frost blocking the flow of air
