Frigidaire air purifiers move room air through a pre-filter and a HEPA or combination filter, and some models add a carbon layer for odors, an air quality sensor that adjusts fan speed, and Wi-Fi control through an app. With few moving parts, the fan motor, control board and sensor are the main components that can fail.
We start with filter fit, reset steps and sensor cleaning, since those cause most complaints, then test the fan motor and control. If the fault is in a part that makes repair poor value on a small unit, you hear that before any work is done.
