NewAir AC-12000H Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin an important defrosting cycle if necessary, to keep your outdoor unit from plugging up. The defrost sensor board looks to a sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
Some warnings of an inadequate outdoor defrost sensor board
- The main control board may throw an error code if the defrost control board fails
- Your HVAC system will stop operating for the simple fact of the fact that there is too much frost
- Defrost session has not run for quite some time even though there is excessive frost on the external unit
