International Comfort Products GDL100N16A3 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin an important defrosting cycle if necessary, to rid your unit of frost that can build up. The control board relies on a temperature sensor that can be found near the condenser, in order to verify when the defrost cycle should begin.
What red flags are there that my International Comfort Products defrost sensor board is almost going bad?
- Your system could not work due to the fact of too much frost
- The main control board may issue an error number if the defrost control board fails
- Self defrost sequence never kicks in especially when there is a rather large amount of frost built up
