International Comfort Products T9MPD100J20A1 Air Pressure Switch
The job of the pressure switch is to determine whether or not the blower is blowing air. Most air pressure switches have a manual reset feature, which makes you reset it by hand or the entire system will not run. This pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from potential hazards in the house.
Signs to Look Out for when the Switch is Beginning to Fail
- The blower fan refuses to function.
- The right indoor temperature seldom reached.
- Incorrect volt range running through the pressure switch.
