Samsung AVMHH128CA0 Air Pressure Switch
The main job of the pressure switch is to determine whether or not the blower fan is circulating the air as it should. A lot of switches are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset or the entire system will not run. This switch is one of the key device to keep you safe.
Signs that your Pressure Switch is Failing
- The furnace will not ignite the gas.
- Inaccurate voltage reading.
- The right indoor temperature is almost never fully attained.
