Lennox Elite 14 Air Pressure Switch
The main job of the air pressure switch is to figure out if the air blower is on and running. This switch is one of the critical facets of the HVAC safety checks that are dedicated to stop injuries or explosions. Some different switches are constructed with a manual reset, which makes you reset it by hand or the whole HVAC system will not continue operation.
How to Know when the System Pressure Switch is Failing
- The expected temperature in the house is never reached.
