International Comfort Products H8MPT125J20B1 Defrost Sensor Board
The defrost control board will begin an important defrosting cycle which actually helps to continue normal heating and cooling operations. It is relayed information from a sensor which is near the condenser somewhere, in order to verify when to initiate the defrosting cycle.
Indications the AC defrost sensor board needs a replacement ASAP
- Most systems will cease to function due to too much frost
- The main control board may show an error signal produced by too much frost
- The defrost feature will not initiate even though there is a large amount of frost on the unit
