DeLonghi PAC 400 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrosting phase which aids to keep the outdoor unit free from frost build-up. It looks to a defrost sensor located in the outdoor unit to decide when the defrost cycle should begin.
Indications your defrost board is dead
- The main circuit board may signify a type of error code referring to a failing defrost control board
- Defrost session will not initiate especially when there is a rather large amount of frost that makes the unit run like crap
- Most systems will stop operating at all because of the amount of frost on the outdoor unit
