Frigidaire FRS22PYW20 Defrost Sensor Board
The defrost control board determines when or if to start an important defrosting cycle in order to defrost your outdoor unit. The defrost board depends on a temperature sensor located near the condenser to determine when the defrost cycle should begin.
Some clues your Frigidaire defrost sensor board will soon need to be replaced
- The AC may not operate because of the safety features installed
- Self defrost sequence never kicks in even though there is a lot of frost on the outdoor unit
- Your main control board might give out an error of some type produced by too much frost
