Carrier 24ABA324A0030010 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost sequence which actually helps to keep your outdoor unit from plugging up. The defrost sensor board relies on a specific sensor which is near the condenser somewhere, in order to agree when to initiate the defrosting cycle.
How can I tell if my defrost board has a need to be replaced?
- Defrost session does not run even though there is quite a bit frost on the unit
- The main board might issue a particular error code if the defrost board fails
- The HVAC system could end up not running for the simple fact of the fact that there is too much frost
