Samsung AVMHH105EA0 Air Pressure Switch
The primary function of this type of switch is to sense if the air blower is actually running. This pressure switch is just one of the many indispensable hardware devices made to keep you safe. Some pressure switches may have a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Symptoms of a Broken Pressure Switch
- Incorrect voltage range reading.
- The proper indoor temperature is hardly ever reached.
- The blower fan will not operate properly.
