International Comfort Products MF20N2600A1 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase if necessary, to continue normal heating and cooling operations. The defrost sensor board looks to a specific sensor located somewhere by the condenser to decide when to begin.
Easy warnings your defrost board has to be replaced
- Your HVAC system will not work at all because of way too much frost build-up
- Defrosting does not run even though there is quite a bit frost that needs to be removed
- The main circuit board may show a type of error code when the defrost board fails
