International Comfort Products T8MPN075B12B1 Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence which actually helps to keep your outdoor unit from plugging up. The defrost board depends on a defrost sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
Easy warnings of a worsening outdoor defrost sensor board
- Unit defrost session will not initiate even though there is a lot of frost that has built up
- Your HVAC system will not operate for the simple fact of the frost blocking the flow of air
- Your main control board may throw an error number produced when the defrost board is bad
