Lennox G40UH-60D-155 Air Pressure Switch
The main job of the pressure switch is to figure out if the air blower is actually running. Various air pressure switches may have a manual reset, which, of course, means that it would have to be reset by hand or else the system will cease to function. This is one of the key facets of the HVAC safety checks that are dedicated to stop injuries or explosions.
Signs to Look for when your Air Pressure Switch is Starting to Go Bad
- The furnace or AC is unable to operate.
- Inaccurate electrical voltage reading.
- The desired indoor temperature is rarely achieved.
