Carrier 48XZN060130300 Air Pressure Switch
The primary function of this type of switch is to sense if the air blower is on and running. Some different switches are constructed with a manual reset, which means you have to physically reset it or the whole HVAC system will not continue operation. This is just one of many mechanisms designed to keep you safe.
Signs to Look for when your Air Pressure Switch is Starting to Go
- Inaccurate electrical voltage being read from the pressure switch.
- The set temperature indoors is almost never reached.
- The furnace can not ignite.
