Mitsubishi MSY-A17NA Air Pressure Switch
The primary function of the switch is to determine whether the main blower is blowing air. Some particular air pressure switches are constructed with a manual reset, from which it would have to be reset manually or else the system will cease to function. This switch is one of many other facets of the HVAC safety checks that are dedicated to keep your family safe and sound.
What to Look for when the System Pressure Switch is Starting to Go
- Wrong volt reading from the switch.
- The furnace will not operate.
- The expected temperature seldom fully attained.
