International Comfort Products GPSM36H100F Air Pressure Switch
The function of the air pressure switch is to determine whether the main blower is circulating the air as it should. A lot of switches can have a manual reset, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation. The air pressure switch is a very critical piece of the safety system that is in place to keep you safe from potential hazards in the house.
Evidence of a Failing Air Pressure Switch
- Inaccurate volt range being read from the pressure switch.
- The set temperature seldom reached.
- The furnace or AC can not run correctly.
