Frigidaire FRS123LW10 Defrost Sensor Board
The defrost control board will determine when to initiate the defrost cycle which helps to rid your unit of frost that can build up. The defrost board relies on a sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
Symptoms of an ineffective defrost board
- The main circuit board may throw an error number when the defrost board fails
- Self defrost sequence never starts especially when there is a rather large amount of frost on the outdoor unit
- Most systems will cease to function for the simple fact of the amount of frost on the outdoor unit
