About 1 1/2 months ago my single switch autotopoff units relay box starting buzzing like mad. It had gotten to the point that I was about to purchase a new one. So loud in fact that to watch TV you had to unplug the topoff or you couldnt even hear the TV.
Needless to say I was confused why all of a sudden it would start doing this. I have not had it but a few months.
I thought maybe cleaning the switch would make a difference, so last night I unplugged the water supply ( and for some reason left the relay plugged in ) which in this case was good.
After cleaning the switch I started to mount it back in the sump again as I passed the switch by the skimmer putting it in place BUZZZZZZZZZZZZ. I pulled my hand back and it stopped. HMMMM!?!?!?
I put the switch near the skimmer pump ( Sedra 3500 ) again BUZZZZZZ, pulled it away and it stopped again. Then it hit me. About 1 1/2 months ago I turned my skimmer around ( for some as of now unknown reason ) this put the pump right next to the switch, where as before it had been on the opposite side. Thats when I put 2 & 2 together and realized that it is indeed 4 LOL.
Apparently the magnet in the Sedra was making the siwtch go nuts and was causing the buzzing. I put the skimmer back in its original position and not even the slightest buzz is to be found now.
Anyone know what would have caused this. I realize it was most likely the magnet, but why? At least thats what I could come up with.
Anyhow I thought it was kinda funny, and thought I would share.
