I posted about mine not too long ago. I have 2 of them, they worked fine forever, now this season, I am pretty sure one is not working (never have to fill it more than a half bag of corn) but it works when I hit the test button.
The other, I never hear it go off but I fill it constantly and I do see corn on the ground at time, if i hit test it goes off. But this one is also lower to the ground and I see deer eating out of the spinner plate, so not really sure if it works or they are using it as an on demand feeder
I may change the batteries and see if that makes a difference or not.
Before when it wouldn’t go off during the set time, I could hear a faint clicking sound inside it when the clock hit the time it was supposed to go off, so I thought that it was a relay trying to close.
The small AA battery that runs the clock, has to close a relay that turns on the motor to run the spinner.
So when I changed out the AA for a fresh Energizer, it seemed to work fine, then a week later, it went right back to doing the same crap.
I think its a relay inside that causes them to not go off.
When you have a problem like that, it’s hard to determine what’s wrong in the field, so I just replaced the POS with one that I know will work
