International Comfort Products H8MPL100J20B1 Air Pressure Switch
The actual job of this type of switch is to see if the blower is on and running. The vast majority of pressure switches made today are issued with a manual reset feature, which makes you reset it by hand before the HVAC system will continue. This pressure switch is part of a small, but important collection of devices that are created to keep you safe.
Signs of a Rapidly Declining Air Pressure Switch
- Wrong voltage running through the pressure switch.
- The proper temp is almost never fully achieved.
- Furnace refuses ignite the gas.
