Carrier 24ABR342G0030010 Defrost Sensor Board
The defrost sensor control board commences the defrost sequence in order to keep your outdoor unit from plugging up. The control board is influenced by a sensor located somewhere by the condenser to decide when the defrost cycle should begin.
Subtle hints the defrost sensor board is on its last leg
- Defrost session never runs even though there is quite a bit frost on the unit
- Your main control board could throw a particular error code produced by too much frost
- Most systems will stop functioning due in part to the safety features installed
