International Comfort Products C8MPL125J20B1 Defrost Sensor Board
The defrost control board determines when or if to start the defrosting phase if necessary, to continue normal heating and cooling operations. The defrost board is influenced by a temperature sensor located near the condenser to make the decision on when to begin.
How do you know if your defrost sensor board is about to go out?
- The HVAC system control board may signify a particular error code produced when the defrost board is bad
- Unit defrost session does not begin especially when there is a rather large amount of frost on the external unit
- The system will not operate for the simple fact of way too much frost build-up
