What to do if 3M X90w Projector shows 'Check the Air Flow'?
- NNathaniel MyersAug 8, 2025
If your 3M Projector displays a 'Check the Air Flow' message, it indicates the internal temperature is rising. Turn the power off and let the projector cool down for at least 20 minutes. Then, check for any blockage of the air passage, if the air filter is dirty, and if the surrounding temperature exceeds 35°C. After addressing these issues, power the unit on again. If the message persists, set the FAN SPEED in the SERVICE menu to HIGH.
