My upper oven, lower heating element burnt out .

Shut off power to oven. Removed upper oven door and cooking racks. Removed 2, 1/4" bolt, pulled element away from oven back wall and unplugged the 2 wires that went into the heating element and removed the element. Reinstalled the new element by plugging in the 2 wires to the element, pushing the wires back through the back of the oven and reinstalled the 2, 1/4" bolts. Reinstalled the cooking racks and oven door. The complete from start to finish time took about 15 minutes.
