Venting a microwave outside typically costs $300 to over $1,000, with the final price depending heavily on labor (often $100-$300+ for installation) and whether new ductwork needs to be run through walls or ceilings, which adds significant cost and complexity, potentially reaching $2,500+ for major jobs. Simple installations where ducting is already present are cheaper, while routing new ducts, cutting through walls/roof, and patching drywall add hundreds to thousands of dollars in labor and materials.
Some over-the-range microwaves vent outside, some recirculate air and many can do both. Before purchasing a new microwave, check the product specifications, user manual or installation instructions to determine what type of ventilation capabilities it has.
Without adequate ventilation: The microwave can overheat. Internal parts may wear out prematurely.
1. Microwaves do not require an exhaust hood. Over-the-range microwaves can be installed with or without venting to the exterior, and those that vent to the exterior often come with their own built-in exhaust fan. Countertop microwaves, which don't have a fan, also do not require an exhaust hood. 2.
Yes, it's essential to provide clearance space behind and around a microwave for proper ventilation. The required space may vary depending on the model, so consult your microwave's user manual for specific clearance guidelines. As a general rule, it's advisable to leave at least 5 cm (2 inches) of space on all sides.
Typically, you want to have at least 3 inches of clearance around all sides and the top for proper ventilation. For built-in models, refer to your owner's manual for specific clearance requirements.
All convection microwaves ovens require at least 10cm clearance at the sides, approximately 15cm at the rear, and 15–40cm on top.

The installation of a listed and labeled cooking appliance or microwave oven over a listed and labeled cooking appliance shall conform to the terms of the upper appliance's listing and label and the manufacturer's installation instructions.
Type of Range Hood
Ducted range hoods, which vent air outside, are generally preferred for their effectiveness in removing contaminants. In some cases, ductless hoods may be allowed, but they must meet specific filtration and recirculation standards to ensure adequate air quality.
Under-counter placement: Install a microwave drawer below the countertop for a sleek look and easy access.
The charcoal filter is only used when microwave is NOT vented externally.
Countertop microwaves generally require a 1 inch ventilation space from the back of the appliance to the wall. If venting through your roof, installing a Maytag® over-the-range microwave requires at least 3 inches of clearance space between the top of the microwave oven and the transition piece.
Yes, this is normal. Exterior oven surfaces such as the air vents on the rear and bottom of the cabinet, as well as the oven door will get hot during GRILL, CONVECTION and COMBINATION cooking modes.
Outside ventilation requires a HOOD EXHAUST DUCT. Read the following carefully. NOTE: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages.
A microwave draws between five to 10 amps. So, in most cases, you could safely have a range hood and microwave on the same circuit.
Ductless hoods are installed 2 to 3 feet above your stovetop but don't connect to any ductwork. They use suction fans to draw in air, smoke, and grease and circulate it through a charcoal filter. They tend to be the least expensive option, usually running from $200 to $400, including labor installation costs.
Use a Window Fan
When you're cooking, steam, smoke, and lingering odors can fill the air. But a window fan comes to the rescue by pulling out all that stuff and bringing in fresh air from outside. It keeps your kitchen well-ventilated, making it more comfortable to work in.
Ductless range hoods have some drawbacks, including:
Yes, you can DIY an over-the-range microwave install, make sure you have a second person and the right tools. You'll need: a drill, a level, a stud finder, a mounting bracket, safety gear, and a clear wall-to-cabinet plan. No electrician is needed if an existing outlet matches the replacement unit.
Over-the-range microwaves:
Designed to be installed above your stove or cooktop, they save counter space and provide a built-in look. Microwave range hoods, such as those offered by Whirlpool brand, often come with integrated ventilation systems to help remove smoke and odors while cooking.
Microwaves need adequate air clearance on each side, the rear and the top to function properly. This allows good circulation for the intake and discharge air vents.
Will a 60cm cooker fit in a 60cm gap? Despite being freestanding, and therefore easy to relocate when required, a 60cm range cooker from Leisure will fit into a 60cm gap in your existing units much like any standard-width conventional single oven or built-in appliance would.
When planning, you must also consider the distance you allocate around your cooktop. Australian standards state that there needs to be a 50mm clearance to non-combustible surfaces (heat rated splashbacks) or a 200mm clearance to combustible surfaces.
