Lennox G40DF-36A-045 Air Pressure Switch
The actual job of an air pressure type switch is to figure out if the main blower is doing what it is supposed to do. This is one of the key safety creations designed to keep your family safe and sound. Most air pressure switches may have a reset feature that is manual, which makes you reset it by hand or the entire system will not run.
Signs to Look for when the System Pressure Switch is in Need of Replacement
- System does not achieve the desired temperature as set by the thermostat.
- Incorrect electrical voltage being read from the pressure switch.
- Your heating and cooling system will not operate properly.
