So the apex unit itself is making a high pitched buzzing sound and i don't know what to do or how to fix it. I tried to unplug it but the light stays on and the buzzing continues. Any help is highly appreciated
1. Check if there is any debris or blockage in the fan or the unit itself. If there is, remove it.
2. Try resetting the unit by unplugging it and waiting for a few minutes before plugging it back in.
3. If the issue persists, you may want to contact the manufacturer or a professional for assistance.
