Lennox XC17 Air Pressure Switch
The job of the switch is to determine whether or not the main blower is running properly. An air pressure switch is one of the vitally important safety devices that are created to keep your family safe and sound. The majority of pressure switches are equipped with a manual reset feature, which forces the system to be reset physically in order for the system to begin normal operations again.
Signs that the Switch is About to Fail
- Inaccurate volt range being read.
- The furnace refuses ignite.
- The expected temperature is hardly ever fully attained.
