International Comfort Products H8MPV075F14B1 Defrost Sensor Board
The defrost control board controls when to launch the defrost sequence which assists to continue normal heating and cooling operations. The board depends on a temperature sensor located somewhere by the condenser to decide when to begin.
What are some indications that my defrost board has to be replaced?
- Defrost session does not run despite that there is a large amount frost on the outdoor unit
- The primary control board may show an error signal if the defrost control board fails
- Your HVAC system will not operate for the simple fact of frost blocking the fins on the outside unit
