An electric can opener is a motorized small appliance. Electric can openers come in countertop, under-cabinet, and cordless models. On most models, clamping the cutting blade to the edge of the can also activates the motor and the feed gear that turns the can. Once the lid is cut all around, on some models, a switch automatically shuts off the motor.
Disassemble an electric can opener:
- Unplug the power cord. Lift or slide off the cutter assembly depending on the model.
- Unscrew the housing screws and remove the housing from the back plate.
- Use a screwdriver or socket wrench to remove the motor screws, then carefully lift the motor out of the housing.
- Unscrew or unclip internal gears (see Testing Motors) and replace as needed.
Service the on-off switch:
- Unplug the power cord and remove the housing.
- Unscrew the switch cover, if any. Clean the switch contacts with an emery board or fine sandpaper, then remove sanding residue with electrical contact cleaner.
- As needed, use pliers to bend the switch contacts to ensure firm contact between leaves only when the switch is pressed.
