Whirlpool ATR0945RPP0 Air Pressure Switch
The function of an air pressure type switch is to sense if the primary blower is blowing air. This is just one of many safety creations designed to keep you safe. Various air pressure switches are programmed with a manual reset, from which it would have to be reset manually before the HVAC system will continue.
Signs to Look Out for when your Pressure Switch is on its Last Leg
- The blower fan is unable to operate properly.
- Wrong voltage range reading.
- The set temperature indoors is almost never achieved.
