Lennox CB30U-21 Air Pressure Switch
The main job of the air pressure switch is to sense if the blower is doing what it is supposed to do. This switch is one of the most crucial hardware devices made to keep everyone in the house safe. A good number of pressure switches today can have a manual reset, which makes you reset it by hand or the entire system will not run.
Signs to Look Out for when your Air Pressure Switch is on its Last Leg
- Wrong voltage range reading from the switch.
- The right temperature is never achieved.
- The blower fan will not run correctly.
