Unit doesn't stop - tamping noise
 

Compactor won't shut off - makes a tamping noise. I assume this is because the top limit switch is bad (it is adjusted right and pushes in the switch). I cannot find this model number in any listing.:confused:

Double check the model number. If it is 665604000, then the number is probably too old. You can get a part number directly off the switch and use the search on this page, right below your post or post the number here and we'll find it.
