Samsung AVMWC020CA0 Air Pressure Switch
The reason for the existence of this type of switch is to sense if the blower is doing what it is supposed to do. This switch is just one of the many indispensable aspects of the whole safety system that is intended to keep everyone in the house safe. A good number of pressure switches today are issued with a manual reset feature, from which it would have to be reset manually before the entire HVAC system will continue operating again.
Symptoms that your Switch is Already Going Bad
- Inaccurate voltage being read from the pressure switch.
- The blower fan refuses to run correctly.
- The proper temp is almost never reached.
