International Comfort Products PGMD42G0606 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin an important defrosting cycle which assists to continue normal heating and cooling operations. The board depends on a temperature sensor located near the condenser to make the decision on when to begin.
Warnings your defrost board needs to be replaced
- AC and heating system could stop functioning for the simple fact of way too much frost build-up
- Self defrost sequence never starts even though there is a lot of frost on the external unit
- The main control board may issue an alphanumeric error code produced by too much frost
