International Comfort Products TDE075B12G1 Defrost Sensor Board
The defrost sensor control board will determine when to initiate the defrosting phase which actually helps to keep the outdoor unit free from frost build-up. The control board looks to a sensor located near the condenser to determine when to initiate the defrosting cycle.
Signs your outdoor defrost sensor board will die soon
- AC and heating system could stop functioning due to the frost blocking the flow of air
- The control board could signify an error signal produced by a bad defrost control board
- Defrost mode has not run for a while despite the fact that there is quite a bit frost on the external unit
