The defrost sensor board controls when to launch the defrost sequence if necessary, to keep the outdoor unit free from frost build-up. The board is influenced by a specific sensor located in the outdoor unit to ascertain when to begin.
Major warnings of a failing defrost board
- The control board could throw a specific error code if the defrost board goes out
- The defrost feature never kicks in even though there is a large amount of frost in the way
- The system may not run for the simple fact of way too much frost build-up
