Frigidaire FRS093LW11 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrosting phase which may be needed in order to keep the outdoor unit free from frost build-up. The defrost board depends on a specific sensor that can be found near the condenser, in order to make the decision on when to begin.
Major indications your Frigidaire defrost sensor board needs to be replaced
- Your HVAC system will not run for the simple fact of way too much frost build-up
- The main circuit board could throw an error code referring to a bad defrost board
- Defrosting will not initiate despite the fact that there is a lot of frost built up
