Haier CPR10XC9-L Air Pressure Switch
The reason for the existence of an air pressure type switch is to sense whether the air blower is running. This switch is one of the critical mechanisms designed to keep everyone in the house safe. A lot of switches may have a reset feature that is manual, from which the switch will have to be manually reset before the HVAC system will continue.
Clues that your HVAC Air Pressure Switch is Starting to Fail
- Your system doesn't get to the correct temperature.
- Incorrect electrical voltage running through the pressure switch.
- The blower refuses to run.
