Turn off the oven breaker in your service panel. Ensure that the oven has had time to cool prior to performing the repairs.
Open the oven door containing the loose handle.
Locate the hole on each door hinge, near the doorjamb. Insert the door pins that were included with the range into the holes. If you no longer have the door pins, insert an Allen wrench into each of the holes.
Close the door until it stops. The door pins or Allen wrenches prevent the door from closing completely.
Grasp the door by the sides, not the handle, and then lift the door up and off of the oven. Place the door face-down on a solid, padded surface, such as a piece of carpet.
Remove the two screws at the top of the inner door panel, as well as the two screws on the bottom of the door.
Lift the inner door panel out of the outer door panel, and then set the inner door panel aside.
Locate the door handle screws, which are located at the top of the inner portion of the outer door panel. Grasp the door handle with one hand, and tighten the two screws until the handle is secure.
Place the inner door panel back into the outer door panel, and then reinstall the four screws.
Lift the door with both hands by the sides, and then insert the hinges into the hinge slots on the bottom of the door, as far as the hinges will go. Rotate the top of the door toward the oven.
Open the oven door completely, and then remove the door pins or Allen wrenches from the hinges.
Close the oven door, and then restore power to the appliance.
