International Comfort Products GDJ075M16C2 Defrost Sensor Board
The defrost control board initiates the defrost sequence which may be necessary to keep the outdoor unit free from frost build-up. The defrost board is relayed information from a temperature sensor which is near the condenser somewhere, in order to agree when to begin.
Warnings of a dying defrost board
- The control board could throw an error signal if the defrost board fails
- The system will cease to operate for the simple fact of the safety issue that the frost poses
- The defrost sequence never starts despite the fact that there is a lot of frost on the unit
