I have a sinkmaster bonecrusher-no idea what size–looks smaller. I get a hum, the reset button doesn’t help, the blades move freely, and there is no opening that I can find for an allen wrench. HELP!
hi i am new to this web site concerning your problem i have the same. i take a pair of plyers place the handles down into the blades place a bar in the jaws and turn back and front. it is rust or a piece of materal jammed in between . it always works for me.
