Carrier LJE Air Pressure Switch
The job of the pressure switch is to sense whether the primary air circulator is on and running. This is one of the key devices designed to keep you safe. The majority of pressure switches may have a manual reset, which means it will have to be manually reset in order for the HVAC system to continue running.
What to Look for when your Pressure Switch has Gone Bad
- The correct temperature is never achieved.
- HVAC system refuses to run correctly.
- Bad volt reading.
