Loud AquaRite SWG after board replacement

[MarcBalcer]

Hi. Recently replaced SWG board on my Aquarite. I ran it for a day or two and it was working fine without replacing the metal cover display plate. I put the plate on and now it is making a loud vibration/humming noise. When I take the cover plate off, it is a normal quiet hum. In both situations, it is generating chlorine just fine. I have jiggled and tried to reseat the board to no avail. It seems like the panel is amplifying the vibration. Any thoughts? Just for fun, here are the numbers from the panel. I believe they are fine.

3.3
84
23.9
5.5
54p
-3.1
Al - 0
R 1.59
T-15

If i apply upward pressure to the bottom of the box, it sounds normal. But i dont really feel like standing here doing that all summer

Welcome to TFP! I see your question has been sitting with no replies for a few days, so I figured it was time to give this thing a bump. Is it still making that noise?

Tighten the screws that attach it to the house/ post.

Or shim behind it on the bottom.

Or use small pieces of electrical tape around the seam of the cover where they won't interfere with its closing mechanism.

I'm not sure this was it but after having some SWG issues lingering, I discovered that it was set for t-3 instead of t-15. I'm not sure when that started but since them, it has been less loud and hummy. Thanks for your ideas newdude. I lined the edges with electrical tape which helped too.
