Lennox G40UH-36A-070 Air Pressure Switch
The job of an air pressure type switch is to sense whether the primary air circulator is on and running. This is one of the most crucial facets of the HVAC safety checks that are dedicated to keep everyone in the house safe. The vast majority of pressure switches made today have a manual reset feature, which makes you reset it by hand before you can continue using the system.
How is it Known when the HVAC Air Pressure Switch is Going Bad
- Incorrect electrical voltage reading.
- The desired indoor temperature is never reached.
