Carrier KFCEH1901C20 Defrost Sensor Board
The defrost sensor board is jobbed with determining when to begin the defrost cycle which actually helps to keep the outdoor unit free from frost build-up. The defrost board relies on a defrost sensor that can be found near the condenser, in order to determine when to initiate the defrosting cycle.
Indications your Carrier defrost sensor board is in dire straights
- The main board may signify an error of some type when the defrost board fails
- The whole system may not operate because of the amount of frost on the outdoor unit
- Defrosting will not kick in even though there is a large amount of frost on the external unit
