International Comfort Products PGMD18G0406 Air Pressure Switch
The primary function of the switch is to see if the primary air circulator is running properly. Some particular air pressure switches are designed with a reset that is manual instead of automatic, which, of course, means that it would have to be reset by hand before the system will continue its normal operation. This switch is part of a small, but important collection of aspects of the whole safety system that is intended to stop injuries or explosions.
Signs of a Nearly Failed Pressure Switch
- The proper temperature in the house is rarely achieved.
- The blower fan refuses to run correctly.
- Bad electrical voltage being used by the switch.
