Whirlpool ATR1543BPP0 Air Pressure Switch
The primary function of the air pressure switch is to determine whether or not the main blower is running properly. The vast majority of pressure switches made today have a manual reset feature, by which you must manually reset it or the whole HVAC system will not continue operation. This pressure switch is part of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions.
Symptoms that the Air Pressure Switch is Beginning to Go Bad
- The proper temperature in the house is never achieved.
- The furnace is unable to run.
