There is odor, but the color of the overall air quality doesn’t change.
Is the overall air quality red or orange?
The color of the overall air quality is determined by the worst level sensed, whether that is a PM concentration or odor. The PM concentration level may be worse than the odor level.
The odor (gas) sensor is designed to detect harmful gases. Strong food odors may not register as harmful, but the Deodorization filter will minimize them.
The color of the overall air quality stays red.
Move the appliance to a different room and see if the color changes.
Clean the PM1.0 sensor.
Remove the power plug from the outlet and reconnect it one minute later.

If the PM concentration is low and the odor level is high, the overall air quality will reflect the odor level.
