Fujitsu ASU12RMLQ Air Pressure Switch

The reason for the existence of the air pressure switch is to figure out if the primary air circulator is running properly. Some pressure switches may have a manual reset, which, of course, means that it would have to be reset by hand in order for the HVAC system to continue running. This is part of a small, but important collection of mechanisms designed to keep everyone in the house safe.

Signs to Look for when the System Pressure Switch is Starting to Fail

Bad volt being read from the pressure switch.
The furnace can not ignite.
Your system doesn't get to the correct temperature when set by the thermostat.
