Whirlpool ATR0743SPP0 Air Pressure Switch
The reason for the existence of the switch is to see if the blower fan is actually running. This switch is one of the most crucial facets of the HVAC safety checks that are dedicated to keep everyone in the house safe. Most air pressure switches are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset before the HVAC system will continue.
Signs that the HVAC Air Pressure Switch is Going Bad
- Your furnace can not run.
- Incorrect electrical voltage being used by the switch.
- The correct temperature indoors is hardly ever fully attained.
