Lennox G40DF-24A-045 Air Pressure Switch
The actual job of this type of switch is to determine whether or not the air blower is circulating the air as it should. This is one of the key facets of the HVAC safety checks that are dedicated to stop injuries or explosions. The vast majority of pressure switches made today are constructed with a manual reset, from which it would have to be reset manually before the entire HVAC system will continue operating again.
How is it Known when the Switch is Beginning to Go
- The blower fan will not run.
- Bad electrical voltage running through the pressure switch.
- The right temp seldom attained.
