International Comfort Products PGAD24D1K1 Air Pressure Switch
The actual job of an air pressure type switch is to determine whether or not the blower fan is actually running. This is one of the key mechanisms designed to keep everyone in the house safe. Various air pressure switches are constructed with a manual reset, which makes you reset it by hand or the entire system will not run.
Warning Signs that the HVAC Air Pressure Switch is Going Bad
- The expected temperature in the house is never reached.
- Incorrect voltage range reading.
- The blower refuses to run correctly.
