Lennox G40DF-48C-090 Air Pressure Switch
The main job of the air pressure switch is to determine whether or not the main blower is circulating the air as it should. The vast majority of pressure switches made today are equipped with a manual reset feature, by which you must manually reset it or the entire system will not run. An air pressure switch is just one of the many indispensable mechanisms designed to stop injuries or explosions.
What to Look Out for when the System Pressure Switch is in Need of Replacement
- The furnace can't ignite.
- The right temp is rarely attained.
- Incorrect voltage range being read from the pressure switch.
