EdgeStar AP12000HS Air Pressure Switch
The main function of the air pressure switch is to sense whether the main blower is blowing air. An air pressure switch is part of a small, but important collection of aspects of the whole safety system that is intended to stop injuries or explosions. Some different switches may have a reset feature that is manual, which means it would need to be reset before the entire HVAC system will continue operating again.
What to Look for when your Air Pressure Switch is About to Fail
- The furnace won't ignite.
- Inaccurate electrical voltage running through the switch.
- The proper indoor temperature is rarely fully achieved.
