Carrier 38AK Defrost Sensor Board
The defrost sensor control board initiates the defrost sequence if necessary, to keep your outdoor unit from plugging up. The defrost board depends on a sensor located near the condenser to decide when the defrost cycle should begin.
Some warnings your defrost board should be replaced
- Defrost mode has not run for quite some time even though there is excessive frost that needs to be removed
- The system will cease to operate because of way too much frost build-up
- The main control board could signify a type of error code referring to the failed defrost sequence
