Well, it got "interesting" last night around midnight. Series of loud clicks. I thought a fan blade had come loose and was hitting the light, so I turned it off. Then realized the on and off clicking was from Alexa, who was not helpful in killing the noise.
Anyone else experience something like this?
No. You weren't having some power fluctuations were you? But usually when that happens it doesn't click, but reboots, and then makes its welcome noise.
