Yes, microwave ovens need ventilation. However, the venting needs differ according to the model and design. Proper clearance and ventilation are necessary for efficient operation and safety reasons. Adequate external ventilation is a must for microwave ovens without built-in ventilation systems.
Adequate ventilation, especially if the microwave is built into a wall of cabinetry, is a must.
There is no requirement that your Over The Range (OTR) Microwave be vented to the outdoors. All OTR microwave ovens can be set up to either allow the fan to recirculate the air back into the kitchen or be vented to the outdoors.
For an external exhaust the vent is located on the back of the top of the microwave to vent out the roof. If you are venting back into the room it appears to come out of the top at the front.
1" clearance in the rear. The front edge of the microwave (measured at door) should sit at least 3" or more back on the counter or shelf to avoid accidental tipping. If located on the counter near a range, we recommend locating it at least 2 ft away.
Ducted or vented microwaves feature exhaust fans that vent air outside of the house. Recirculating, non-ducted or updraft microwaves filter air then push it back into the kitchen. Convertible microwaves give you the option to select your ventilation type.
Check your cabinet above the microwave for a duct that directs exhaust outside your home if your microwave contains intake vents on the bottom of it. The vent is sometimes connected to the back wall behind the device instead of going through the cabinet above the microwave if it's vented to the outside of your abode.
Convertible means it can vent through the wall or ceiling using a duct, or can be converted to non-venting (filters the air and blows it back into the kitchen) with Recirculation Kit Part Number W10294733 which is available from your dealer or an authorized parts distributor.
A microwave oven, designed exclusively for a kitchen countertop, has vents that are built into the back of microwave. If installed into a cabinet, these vents will be blocked and unable to release steam from the microwave,.
Countertop microwaves are microwaves designed to be placed on the kitchen counter. On the other hand, built-in microwaves are microwaves that are neatly tucked into a cabinet or a wall.
Over-the-range models are just that: They're installed over the range. The built-in category includes models designed only to be built in—surrounded by cabinetry or built into the wall. Microwave drawers fall into this group and can be placed under the countertop or below a wall oven.
Since a countertop microwave is designed to rest on a countertop, the vents are often placed on the sides or top to ensure the vents have proper air space to clean out dust and expel hot air during operation. These vents cannot be covered in the built-in hole, as it may cause the microwave to overheat or malfunction.
Built-in microwaves can be installed into a wall or cabinet for convenient operation. With a similar capacity to other microwave styles, the built-in design has the advantages of saving counter space and being able to be installed away from the range, allowing multiple people more space to cook together.
Can all microwaves be built-in? Not all microwaves can be built-in as they are available in either freestanding or built-in models. We recommend that you install built-in microwaves into a cabinet, but if you do wish to install a freestanding model as a built-in we have built-in trim kits that allow you to do so.
Convertible vents offer improved air quality by venting air outside of the kitchen. They can also convert into a ductless system that uses air filters. Recirculating microwave vents send your kitchen air through a series of aluminum, carbon, or charcoal filter vents.
You can vent it traditionally (ie to an outside vent) or recirculate it, which means just that--the air recirculates as opposed to being vented outside. There is an air filter used for this that comes with the unit.
Most microwaves don't require venting. However, if yours does, venting it from an inside wall is a simple matter of running the duct pipe to the nearest external wall. Alternatively, you can choose to run the duct pipe through the wall to the central ventilation.
Ventilation: Do not block air vents. If they are blocked during operation, the oven may overheat and eventually cause oven failure. For proper ventilation, keep three inches of space between the oven's top, sides, rear and the area where the unit is to be installed.
In many cases there are visible vents at the top of the microwave face frame, or a top panel that opens as a flap when the exhaust fan of the microwave is activated. In either example, the cooking by-products are filtered through the filter medium, which is important.
All current over the range microwaves and Advantium ovens can be installed over gas cooking products up to and including 5 burner stoves. As long as the 66" minimum from the floor to the top of the unit is followed there will be no performance or warranty concerns.
Proper ventilation allows the appliance to function correctly. So, yes, countertop microwave requires ventilation, but not external ventilation. The primary thing you need to do is ensure proper clearance at the sides, rear, and top of the microwave.
Built-in microwaves are similar to over-the-range microwaves, except that they don't sit above the oven, and they do not replace a range hood. Instead, built-in microwaves can be placed on an island or mounted on a wall or cabinet.
If you have ample counter space and do not want to spend all the extra money on custom-built microwaves, then a countertop microwave would work best for you. However, if you have an extremely small kitchen and need to utilize all the available space, a built-in microwave works best for you.
