International Comfort Products GPSM60L100F Defrost Sensor Board
The defrost sensor control board controls if and when to commence the defrosting phase which actually helps to continue normal heating and cooling operations. The defrost board relies on a specific sensor located somewhere by the condenser to determine when the defrost cycle should begin.
Red flags the defrost sensor board will die soon
- The defrost feature does not begin despite the fact that there is quite a bit frost built up
- Most systems will not run for the simple fact of the safety features installed
- The main control board may show an error of some type if the defrost control board fails
