Carrier P4 Air Pressure Switch
The main job of an air pressure type switch is to sense if the blower is circulating the air as it should. This switch is just one of many devices designed to stop injuries or explosions. The majority of pressure switches may have a manual reset, which means you have to physically reset it in order for the HVAC system to continue running.
Signs of a Broken Pressure Switch
- Your furnace will not operate at all.
- Incorrect voltage reading from the switch.
- The desired temperature indoors is never reached.
