Replacing oven door handles requires a new door handle, a screwdriver, a socket wrench and the oven's manual. To ensure that the new handle fits the oven door, bring the old handle to the store, or find the part number in the manual or on the manufacturer's website.
To replace the handle, open the oven door to gain access to remove the screws at the top. Remove the front panel of the oven door from the rear panel. Use the socket wrench to remove the bolts holding the old handle in place. Place the ends of the new handle through the holes and reattach the bolts. Reverse the beginning steps to put the oven panels back together.
