Hamilton Beach can opener dead, anything common to check inside?

check the cord first before you even open it up. Ive seen multiple instances of these cheap appliances getting yanked by the cord, the plastic strain relief is a joke. One snapped off one of my neighbors openers while it was on the counter being used.

good point, use a multimeter to test for continuity between the leads when the lever is pressed down. That will rule out the cord.
 
the gears in mine were definately plastic, snapped one tooth and the whole thing slipped every rotation. Tried glueing it and it lasted about 3 cans before it broke again
