International Comfort Products H8MPL075B12A1 Air Pressure Switch
The function of this type of switch is to determine whether or not the blower is blowing air. This switch is one of many other aspects of the whole safety system that is intended to stop injuries or explosions. The vast majority of pressure switches made today may have a reset feature that is manual, by which you must manually reset it before the HVAC system will continue.
Warning Signs that the System Pressure Switch is About to Fail
- The desired temp is hardly ever reached.
- The furnace is unable to ignite the gas.
