SPT WA-1420H Defrost Sensor Board
The defrost control board initiates an important defrosting cycle which actually helps to remove frost build-up that may accumulate. It is relayed information from a specific sensor located in the outdoor unit to agree when the defrost cycle should begin.
What happens when my defrost board is in need of replacing?
- Self defrost sequence does not begin even when there is a large quantity of frost that needs to be removed
- Your main control board may throw a type of error code produced by too much frost
- Your HVAC system will stop running at all because of frost blocking the airflow outside
