International Comfort Products H9MPV075F12B1 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrost cycle which helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board relies on a sensor that can be found near the condenser, in order to agree when to initiate the defrosting cycle.
What warnings should I watch out for to know if my defrost board really needs to be replaced?
- The control board could signify a specific error code when a defrost board fails to initialize
- Most systems will not work for the fact of the amount of frost on the outdoor unit
- Defrosting refuses to initiate even though there is excessive frost on the unit
