Lennox CB30U-31 Air Pressure Switch
The primary function of the air pressure switch is to sense whether the primary air circulator is circulating the air as it should. A lot of switches are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset in order for the system to begin normal operations again. This is one of many other safety creations designed to keep you from harm.
Warning Signs that the Pressure Switch will go Bad
- Your furnace is unable to operate at all.
- Inaccurate voltage range reading.
- The proper temp is rarely reached.
