International Comfort Products HHP436GKA1 Air Pressure Switch
The function of this type of switch is to sense whether the blower fan is blowing air. Some different switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand before the entire HVAC system will continue operating again. This switch is one of many other device to keep everyone in the house safe.
Signals that the Switch has Gone Bad
- Inaccurate voltage range running through the switch.
- Furnace can't ignite.
- The right temp is almost never fully achieved.
