Need Help: beeping Noise from a new D&D 39W UV Sterilizer

[reefo420]

Hello fellow reefers,

I'm experiencing a problem with my D&D 39W UV sterilizer and hoping someone here might have some insights or suggestions. Recently, the unit started emitting a loud buzzing noise. I've assembled and re-assembled it a few times to ensure everything is in place correctly, but the beeping continues.

Here are some details:

• The UV sterilizer is plugged in correctly. However, it came with a plug that I had to connect to another plug with a fuse.
• I've checked the UV bulb and the quartz sleeve for proper seating and cleanliness.
• All electrical connections seem secure, and there's no water or moisture near any electrical contacts.

Despite these checks, the loud buzzing persists whenever the unit is powered on. I've currently unplugged it to avoid any potential risks or further issues.

Has anyone encountered a similar issue with a D&D UV sterilizer before? Any suggestions on what could be causing this buzzing and how to fix it would be greatly appreciated.

Thank you in advance for any help or advice you can provide!
