A Kenmore glass hob range is a type of electric hob that has a smooth glass surface. These forms of hobs are also called ceramic hobs. Repairing damage to the top of the glass is a simple process. Only chips can be repaired. If the glass itself it broken or has large cracks, then you will have to replace the entire hob glass, which is still cheaper than replacing the entire stove.
Sand the chip with sandpaper to remove some of the jagged edges from the chip. You will not be able to patch the chip, but you can make it safe to cook on the stove again.
Make a paste from baking soda and water. Scrub the paste into the chip with a soft cloth. Buff the chipped area until the chip is smooth to the touch and you can glide your finger between the chip and top glass surface without feeling a sharp edge.
Rinse the area with water to remove baking soda residue.
Turn off the power to the hob from the circuit breaker. Disconnect the wires from the hob with your hands or pliers.
Lift any broken pieces of glass carefully so that you do not cut your hands. Throw the broken glass pieces away.
Unscrew the screws holding the hob in place. Pull the hob up from the back hinges, and pull it gently away from the hinges. You may have to unscrew the glass top from the bottom hinges.
Place the new glass over the stove. Screw the hinges in place and then screw the glass top down. Connect all wires and turn the circuit breaker back on to reconnect power to the stove.
Take safety precautions when working with broken glass. Wear work gloves to protect your hands from cuts, and dispose of the glass into a dumpster or outside dustbin as soon as possible. If you leave the glass in a regular dustbin, the glass can cut through the bag, spilling the contents of the bag onto the ground or cutting the person carrying the bag.
