International Comfort Products HAC260GKA4 Air Pressure Switch
The main function of the pressure switch is to sense whether the primary blower is running. The vast majority of pressure switches made today can have a manual reset, which means you have to physically reset it or the entire system will not run. This is part of a small, but important collection of facets of the HVAC safety checks that are dedicated to keep everyone in the house safe.
Symptoms that your Air Pressure Switch is Starting to Go Bad
- The desired temperature indoors is rarely attained.
- Inaccurate voltage range running through the switch.
- Your furnace is unable to ignite the gas.
