Carrier 58MCB040 Air Pressure Switch
The actual job of an air pressure type switch is to see if the air blower is blowing air. This switch is one of the key aspects of the whole safety system that is intended to keep you safe. Some particular air pressure switches can have a manual reset, which means it would need to be reset in order for the HVAC system to continue running.
Important Signs that the Air Pressure Switch is Starting to Go
- Inaccurate volt being read from the pressure switch.
- Furnace will not ignite the gas.
- The set temp is almost never fully achieved.
