Disconnect the electrical power cord from your Kenmore microwave from the electrical outlet.
Open the microwave door.
Unscrew the screws on the front of the Kenmore’s grill and then pull the grill cover off. The grill is located along the top of the microwave. Once removed, it will reveal the hinge that holds the door in place. You will need to use a Phillips screwdriver.
Find the hinge pin directly above the hinge and pull up on the pin to pull it out from the hinge.
Grasp the bottom of the door and lift upwards until you have removed the door from the lower hinge.
Line the new door up to the lower hinge and set it onto the hinge.
Slide the top of the door into place and insert the pin into the hinge to hold it into place.
Replace the grill and screw it back on and then plug your microwave back in.
