Haier HPAC99ER Air Pressure Switch
The primary function of an air pressure type switch is to figure out if the blower fan is running properly. A good number of pressure switches today are equipped with a manual reset feature, which means it will have to be manually reset or else the system will cease to function. This pressure switch is one of the key facets of the HVAC safety checks that are dedicated to keep you safe.
