Whirlpool ATR0742SPP0 Air Pressure Switch
The actual job of the air pressure switch is to see if the blower is blowing air. Most air pressure switches are designed with a reset that is manual instead of automatic, which means you have to physically reset it or else the system will cease to function. This pressure switch is part of all the safety features in today's HVAC systems in place to keep you safe from harm.
Symptoms that your Air Pressure Switch is Already Failing
- The expected indoor temperature seldom reached.
