Coleman DGAA070BDTA Air Pressure Switch
The main job of the pressure switch is to sense if the air blower is running properly. The air pressure switch is a very critical piece of the collection of safety devices in place to keep you safe from any injuries. Some different switches are programmed with a manual reset, which makes you reset it by hand in order for the system to begin normal operations again.
Clues that your HVAC Air Pressure Switch is Beginning to Go
