Lennox 13HPD-042 Defrost Sensor Board
The defrost sensor board instructs the system to activate the defrost cycle which may be needed in order to continue normal heating and cooling operations. The control board relies on a specific sensor that can be found near the condenser, in order to decide when to begin.
What are the indications that my AC defrost sensor board needs replacing?
- Defrost session will not initiate even though there is excessive frost on the outdoor unit
- Your main control board could throw an error of some type produced by a failing defrost board
- Your system could not work due in part to the frost issue
