International Comfort Products TCH030AKA1 Air Pressure Switch
The primary function of an air pressure type switch is to sense if the blower fan is running. The vast majority of pressure switches made today may have a reset feature that is manual, from which the switch will have to be manually reset in order for the HVAC system to continue running. An air pressure switch is one of the most crucial devices designed to keep you safe.
Important Signs that the System Pressure Switch will Soon Fail
- The correct indoor temperature is almost never reached.
- The blower fan can not run correctly.
- Incorrect voltage range being used by the switch.
