Carrier 38TKB036 Air Pressure Switch
The primary function of this type of switch is to determine whether the blower is running. Some particular air pressure switches may have a reset feature that is manual, which means it will have to be manually reset before the entire HVAC system will continue operating again. This pressure switch is one of the vitally important safety hardware devices made to stop injuries or explosions.
How to Know when the Switch has Gone Bad
- The expected temperature in the house is almost never fully attained.
- The blower will not operate properly.
- Inaccurate voltage running through the switch.
