International Comfort Products PYMC42G1 Air Pressure Switch
The reason for the existence of an air pressure type switch is to sense if the main blower is actually running. This is one of many other facets of the HVAC safety checks that are dedicated to stop injuries or explosions. The majority of pressure switches can have a manual reset, which means you have to physically reset it before the entire HVAC system will continue operating again.
Signals that the System Pressure Switch has Gone Bad
- Incorrect voltage being read.
- The expected temp is almost never attained.
- HVAC system is unable to operate properly.
