International Comfort Products HMH Air Pressure Switch
The reason for the existence of the air pressure switch is to determine whether the primary blower is on and running. Some different switches are designed with a reset that is manual instead of automatic, which, of course, means that it would have to be reset by hand before you can continue using the system. An air pressure switch is part of a small, but important collection of devices that are created to keep you from harm.
Signs that the Switch is Beginning to Fail
- Incorrect electrical voltage being read.
- The furnace refuses ignite the gas.
- The expected temperature in the house is rarely achieved.
