Carrier 58DLA13510022 Defrost Sensor Board
The defrost sensor board will determine when to initiate an important defrosting cycle which helps to keep the outdoor unit free from frost build-up. The board relies on a specific sensor that can be found near the condenser, in order to ascertain when the defrost cycle should begin.
Major indications of an unhealthy Carrier defrost sensor board
- The defrost sequence never starts despite the fact that there is quite a bit frost on the external unit
- Your system could not operate due in part to the fact that there is too much frost
- The primary control board could throw an alphanumeric error code if the defrost board fails
