Lennox G26Q3-75 Defrost Sensor Board
The defrost sensor board determines when or if to start the defrost cycle which helps to defrost your outdoor unit. The control board is relayed information from a specific sensor that can be found near the condenser, in order to determine when the defrost cycle should begin.
What are the indications that my Lennox defrost sensor board is almost going bad?
- The main control board may show a particular error code produced by a bad defrost control board
- The whole system may not run due to the fact of the amount of frost on the outdoor unit
- Defrost mode never kicks in even though there is excessive frost in the way
