International Comfort Products TCH024AKA1 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrosting phase if necessary, to keep your outdoor unit from plugging up. It looks to a defrost sensor located somewhere by the condenser to verify when to begin.
What warnings should I watch out for to know if my AC defrost sensor board is not working properly?
- Unit defrost session has not run for a while despite the fact that there is quite a bit frost that makes the unit run like crap
- The primary control board may show a type of error code if the defrost control board fails
- Your HVAC system will cease to function due to the fact of the frost issue
