Carrier 58CVA11010022 Air Pressure Switch
The job of this type of switch is to sense if the main blower is doing what it is supposed to do. A lot of switches are equipped with a manual reset feature, which, of course, means that it would have to be reset by hand before the system will continue its normal operation. This switch is part of the safety system in place to keep you safe from harm.
Signs to Look Out for when the Switch has Failed
- The desired indoor temperature seldom attained.
- The furnace refuses run.
- Inaccurate voltage being read from the pressure switch.
