International Comfort Products TCA248AKA1 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost cycle which actually helps to keep your outdoor unit from plugging up. The defrost sensor board relies on a temperature sensor located in the outdoor unit to ascertain when to initiate the defrosting cycle.
Key indicators that my International Comfort Products defrost sensor board really needs to be replaced?
- The system may not work at all because of the frost blocking the flow of air
- The primary control board could display an error signal referring to a bad defrost board
- Defrosting has not run for a while even though there is excessive frost that needs to be removed
