Unplug the microwave from the electrical outlet. If the Litton-Aire microwave oven is a countertop microwave, simply lift the microwave off the counter to remove it and place it in the desired area. If the microwave is installed above your stove, the process is a little more involved.
Locate the screws used to bolt the microwave into place and unscrew them.
Remove the front panel of the microwave. It may pop off or it may need to be unscrewed. Behind the front panel, you will find additional bolts securing the microwave in place. Remove these bolts.
Lift and remove the microwave away from the wall. Use the assistance of another person, as the microwave can be quite heavy.
Unscrew the mounting plate, if applicable, and if you do not plan on installing a newer microwave.
