Lennox G43UF-36B-070 Air Pressure Switch
The actual job of the switch is to sense if the primary blower is actually running. The majority of pressure switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again. This switch is part of the collection of safety devices that is in place to keep you safe from harm.
Important Signs that the HVAC Air Pressure Switch is Starting to Fail
- The desired indoor temperature is hardly ever attained.
- HVAC system will not run correctly.
- Inaccurate volt range reading from the switch.
