Carrier 38ESA060 Defrost Sensor Board
The defrost sensor board controls if and when to commence the defrost sequence if necessary, to remove frost build-up that may accumulate. The defrost sensor board relies on a defrost sensor located near the condenser to ascertain when the defrost cycle should begin.
What are some hints that my Carrier defrost sensor board has to be replaced?
- The primary control board might give out an error number if the defrost board fails
- The HVAC system could not operate at all because of the amount of frost on the outdoor unit
- The defrost sequence never starts especially when there is frost that needs to be removed
