International Comfort Products CAC048GKA1 Air Pressure Switch
The function of the air pressure switch is to determine whether or not the main blower is circulating the air as it should. Some particular air pressure switches are programmed with a manual reset, from which the switch will have to be manually reset before the HVAC system will continue. An air pressure switch is part of a small, but important collection of mechanisms designed to keep everyone in the house safe.
Symptoms of a Broken Air Pressure Switch
- Inaccurate volt range reading from the switch.
- The correct indoor temperature is rarely achieved.
- Your furnace refuses ignite.
