Whirlpool ATE0943SPP0 Air Pressure Switch
The reason for the existence of an air pressure type switch is to sense whether the blower is actually running. Some pressure switches are designed with a reset that is manual instead of automatic, which means it will have to be manually reset or the whole HVAC system will not continue operation. An air pressure switch is part of a small, but important collection of safety creations designed to keep you from harm.
Symptoms that your Switch is Beginning to Go Bad
- Your furnace will not operate.
- The desired temperature in the house is almost never achieved.
- Bad volt being used by the switch.
