Carrier 48JZ048090300 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrosting phase which may be needed in order to continue normal heating and cooling operations. It is relayed information from a sensor located near the condenser to make the decision on when the defrost cycle should begin.
What warnings are present when my defrost sensor board is failing?
- The defrost feature has not run for quite some time even though there is excessive frost that makes the unit run like crap
- The main circuit board may issue a particular error code produced when the defrost board is bad
- The system may not operate because of the frost blocking the flow of air
