How to Install the Rear Wall Exhaust on an LG Microwave Oven

If you own a, LG microwave oven, it's important that the unit is properly vented. If the microwave connects to a wall vent, make sure the blower unit blows into the vent. To fully install the rear wall exhaust, remove the microwave from the wall and take out the knockout parts from the microwave’s back, so that the blower unit blows through the rear exhaust in your kitchen.
