Haier CPN14XC9 Air Pressure Switch
The primary function of the pressure switch is to sense if the primary blower is circulating the air as it should. Most air pressure switches have a manual reset feature, which means it would need to be reset or else the system will cease to function. This is part of a small, but important collection of devices designed to keep you safe.
How is it Known when the HVAC Air Pressure Switch is Starting to Fail
- The proper temperature is hardly ever reached.
- The furnace refuses ignite the gas.
- Incorrect electrical voltage running through the pressure switch.
