Ran a couple of inches of water into a wastebasket and set the pump in

the buzzing had stopped. Now I'm beginning to get more curious.

Turned on the cooler. The buzz is back. So the pump change really was
just a coincidence - evidently.

I think you are right - just ignore it.


I'm of the option that if you hit yourself in the head with a hammer,
the noise won't bother you - LOL!
