International Comfort Products TNE125J20G1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which actually helps to keep your outdoor unit from plugging up. The control board is relayed information from a sensor located in the outdoor unit to agree when the defrost cycle should begin.
Major symptoms the AC defrost sensor board is going out
- Your main control board could throw an error code referring to a bad defrost board
- Defrost session never starts especially when there is a rather large amount of frost on the external unit
- Most systems will stop functioning for the fact of frost blocking the fins on the outside unit
