Lennox XC21-024 Air Pressure Switch
The main job of the switch is to sense if the primary air circulator is circulating the air as it should. A good number of pressure switches today are designed with a reset that is manual instead of automatic, which makes you reset it by hand or the entire system will not run. This pressure switch is just one of the many indispensable devices designed to keep you safe.
What to Look for when the System Pressure Switch is Starting to Go
- Bad electrical voltage reading from the switch.
- The correct temp seldom attained.
- Your heating and cooling system refuses to function properly.
