International Comfort Products NTPM125KNA1 Air Pressure Switch
The main job of the pressure switch is to determine whether the primary air circulator is doing what it is supposed to do. Some particular air pressure switches may have a manual reset, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again. The air pressure switch is part of all the safety features in today's HVAC systems in place to keep you safe from harm.
Warning Signs that the Switch is Already Failing
- HVAC system does not get to the correct temp.
- The furnace won't run.
- Wrong voltage being read from the pressure switch.
