Cord replacement

If the break is near the plug, cut it and put a new plug on (three prong if the original is, two otherwise). If the break is too close to the cabinet, you'll need to replace the whole wire with something of suitable size (remember, this is probably a 1000-1500 watt appliance!). Opening the cabinet shouldn't be too difficult and if you replace one wire at a time, you can't get lost. You may need to cut the wire short of a junction of several wires (better than cutting all of them and wiring them in to a new junction with a wire connector). I would tend to solder the wires you've just connected, although many would suggest those screw on wire connectors. A lot has to do with how much room you have in the cabinet. If you aren't at all mechanically inclined, get a friend to do it. Or buy a new unit (a last resort in THIS household and not used until the unit is thoroughly unusable!).
