Haier CPN10XCJ Air Pressure Switch
The function of this type of switch is to determine whether the air blower is blowing air. Some different switches can have a manual reset, which forces the system to be reset physically before the entire HVAC system will continue operating again. This pressure switch is part of a small, but important collection of devices designed to keep your family safe and sound.
What Signs are Present when your Air Pressure Switch is on its Last Leg
- The furnace can't operate.
