Carrier 30HH Defrost Sensor Board
The defrost control board will begin the defrost cycle in order to continue normal heating and cooling operations. The defrost sensor board depends on a temperature sensor which is near the condenser somewhere, in order to make the decision on when the defrost cycle should begin.
How can I tell if my Carrier defrost sensor board is on its last leg?
- The system will cease to function for the fact of the amount of frost on the outdoor unit
- Your main control board may issue a particular error code produced by a bad defrost control board
- Defrost session has not run for a while even though there is excessive frost on the outdoor unit
