Whirlpool ATR0753SPP0 Air Pressure Switch
The function of the pressure switch is to determine whether or not the blower fan is blowing air. An air pressure switch is just one of the many indispensable facets of the HVAC safety checks that are dedicated to keep your family safe and sound. The majority of pressure switches are programmed with a manual reset, which means it would need to be reset before the system will continue its normal operation.
Precursors that the System Pressure Switch is About to Fail
- The expected temp is never achieved.
- The furnace or AC will not function properly.
- Bad volt range being used by the switch.
