DeLonghi PACT100P Defrost Sensor Board
The defrost sensor board initiates the defrost sequence which helps to keep your outdoor unit from plugging up. The defrost board relies on a sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
Easy warnings the defrost sensor board will eventually need to be replaced
- Your main control board may throw an error signal produced when the defrost control board fails to receive a signal
- The HVAC system could stop working due in part to frost blocking the fins on the outside unit
- Self defrost sequence refuses to run even when there is a large quantity of frost that has built up
