International Comfort Products CHP042AKA1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrosting phase which aids to continue normal heating and cooling operations. It looks to a specific sensor located near the condenser to decide when to initiate the defrosting cycle.
Symptoms the defrost sensor board will not last the year
- The main board may show a specific error code produced when the defrost board is bad
- AC and heating system could end up not running because of too much frost
- Defrosting refuses to run even though there is excessive frost built up
