International Comfort Products NTVM075GFA1 Air Pressure Switch
The reason for the existence of the air pressure switch is to see if the blower fan is actually running. Some particular air pressure switches can have a manual reset, by which you must manually reset it before the entire HVAC system will continue operating again. This switch is part of the safety system that is in place to keep you safe from injury or explosions.
What to Look for when the Switch is in Need of Replacement
- Furnace can't ignite the gas.
- The desired temperature is never attained.
- Incorrect voltage being read from the pressure switch.
