Carrier 48XP042090300 Air Pressure Switch
The job of the air pressure switch is to figure out if the blower fan is doing what it is supposed to do. An air pressure switch is one of the critical devices designed to keep you from harm. Some pressure switches may have a manual reset, from which it would have to be reset manually before the system will continue its normal operation.
How is it Known when the Switch has Gone Bad
- The furnace or AC is unable to operate.
- The correct temperature in the house is almost never reached.
- Bad voltage range running through the switch.
