International Comfort Products HHP018AKA1 Air Pressure Switch
The main job of the switch is to determine whether the air blower is blowing air. This switch is one of the most crucial hardware devices made to keep your family safe and sound. Various air pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Evidence of a Broken Air Pressure Switch
- Incorrect voltage running through the pressure switch.
- HVAC system does not achieve the desired temp according to the settings on the thermostat.
- The furnace or AC will not function properly.
