Ya know, you flip the switch and immediately it isn't right and you flip it again. My husband was all WtH? and I said, I found the corkscrew! I felt down inside the drain and there was something but it was sharp and who wants to get cut on something as gross as the disposal? When we opened the cabinet it was obvious as it was sticking out the side of the housing!! Once he removed it, I took it all apart to see how it worked!
We had a run of bad luck with disposals...the kids dropped popcorn kernels into one, blade mechanism broke on another so in the span of 18 months I think we replaced THREE of them! Of course there was the time a beer bottle cap was in one but no damage was done.
