Lennox G40UH-24A-045X Air Pressure Switch
The reason for the existence of the pressure switch is to see if the primary blower is circulating the air as it should. The vast majority of pressure switches made today have a manual reset feature, from which the switch will have to be manually reset before the entire HVAC system will continue operating again. This pressure switch is one of the most crucial devices that are created to keep your family safe and sound.
What to Look Out for when the HVAC Air Pressure Switch has Gone Bad
- Wrong volt being read from the pressure switch.
