Lennox G40DF-36A-070 Defrost Sensor Board
The defrost control board determines when or if to start the defrost sequence which may be necessary to keep your outdoor unit from plugging up. The defrost sensor board relies on a temperature sensor that can be found near the condenser, in order to decide when to initiate the defrosting cycle.
Elements of a bad defrost sensor board
- Air conditioning may stop functioning due in part to the frost issue
- The main circuit board might give out an error of some type produced when the defrost board is bad
- The defrost sequence never runs especially when there is frost that has built up
