Haier CPRB07XC7 Air Pressure Switch
The primary function of an air pressure type switch is to determine whether or not the blower is running properly. The vast majority of pressure switches made today have a manual reset feature, which, of course, means that it would have to be reset by hand or the entire system will not run. This is part of a small, but important collection of safety creations designed to keep everyone in the house safe.
Red Flags that your HVAC Air Pressure Switch is Starting to Go Bad
- The blower can not run.
- Inaccurate voltage range being read from the pressure switch.
- The desired temperature in the house is almost never fully achieved.
