International Comfort Products T2A360GKA100 Air Pressure Switch
The primary function of the air pressure switch is to sense if the blower fan is blowing air. Some different switches are constructed with a manual reset, by which you must manually reset it before the HVAC system will continue. The air pressure switch is part of all the safety features in today's HVAC systems in place to keep you safe from injury or explosions.
How is it Known when the Switch is Failing
- The proper indoor temperature is almost never fully attained.
- The furnace can't ignite.
- Inaccurate voltage range running through the pressure switch.
