Carrier DR Air Pressure Switch
The primary function of the pressure switch is to sense whether the primary blower is doing what it is supposed to do. A good number of pressure switches today are equipped with a manual reset feature, which means it will have to be manually reset before the HVAC system will continue. This pressure switch is one of the critical aspects of the whole safety system that is intended to keep everyone in the house safe.
Important Signs that the Switch is Beginning to Fail
- HVAC system does not reach desired indoor temperature.
- The blower fan is unable to run correctly.
- Incorrect voltage range reading.
