Carrier 48GP042090300 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle if necessary, to continue normal heating and cooling operations. It is relayed information from a temperature sensor located somewhere by the condenser to determine when to initiate the defrosting cycle.
What to see if the defrost board is not working right?
- The system may stop operating due to the fact of too much frost
- The defrost feature will not kick in despite the fact that there is quite a bit frost that makes the unit run like crap
- The main control board could signify an error of some type when a defrost board fails to initialize
