International Comfort Products GPCM48L120F Air Pressure Switch
The actual job of the air pressure switch is to determine whether or not the primary air circulator is running properly. This is one of the vitally important safety devices designed to keep everyone in the house safe. Some different switches are programmed with a manual reset, by which you must manually reset it before the HVAC system will continue.
Warning Signs that the Switch is in Need of Replacement
- Incorrect voltage being used by the switch.
- The proper temperature indoors seldom achieved.
- Your heating and cooling system will not operate.
