Whirlpool ATE1242RPP0 Air Pressure Switch
The reason for the existence of an air pressure type switch is to figure out if the air blower is on and running. This is one of the vitally important safety device to keep you safe. A good number of pressure switches today are issued with a manual reset feature, which, of course, means that it would have to be reset by hand or the entire system will not run.
Clues that your HVAC Air Pressure Switch is Starting to Fail
- The furnace or AC can not run.
- HVAC system does not actually get to the right temp.
- Wrong voltage being used by the switch.
