Carrier 58MTB080F10112 Air Pressure Switch
The actual job of the pressure switch is to determine whether or not the blower fan is doing what it is supposed to do. This switch is one of the vitally important safety facets of the HVAC safety checks that are dedicated to keep you from harm. Some pressure switches have a manual reset feature, which means it would need to be reset before the system will continue its normal operation.
What to Look Out for when your Pressure Switch is Beginning to Go Bad
- The furnace will not ignite.
- The correct temp is rarely reached.
- Wrong electrical voltage being used by the switch.
