Fixing an Electrical Knife

An electric knife can dramatically "cut" food preparation time—if it's working properly.

Once the retaining screws are removed, use a flat screwdriver or a putty knife to gently pry the housing apart.


As needed, test the motor in place or remove it for testing and replacement.

An electric knife is a hand-held, motor-driven appliance for cutting food. It's simple in operation: A gear assembly converts a motor's rotary motion into a reciprocating (back-and-forth) action. The driver arm moves a pair of serrated blades, pushing one forward as it pulls the other one back.

Service the driver assembly:
  1. Unplug the electric knife and carefully remove the blades.
  2. Remove the screws at the back of housing and pull the housing apart. Be careful: The blade retainers will be loose and fall out as you open the housing.
  3. Remove all screws holding the driver assembly and motor to the housing. Lift the motor and driver assembly from the housing.
  4. Inspect mechanical parts for wear. If the fan doesn't turn smoothly by hand, clean and lubricate the driver assembly with lightweight grease. Add a drop of light machine oil to each bearing before reassembling parts.
