Frigidaire FRS12PYW10 Defrost Sensor Board
The defrost sensor board determines when to initiate an important defrosting cycle if necessary, to continue normal heating and cooling operations. The control board is influenced by a temperature sensor located near the condenser to make the decision on when to initiate the defrosting cycle.
How do you know if your Frigidaire defrost sensor board is failing?
- The defrost sequence has not run for quite some time even when there is a large quantity of frost on the outdoor unit
- The HVAC system control board might give out an error of some type when the defrost board fails
- The HVAC system could cease to function at all because of too much frost
