How Do You Tell If Your Microwave Is Vented Outside

Here are some tips to help you determine if your microwave is vented outside:

1. Check the Location of Your Microwave

The first step in determining if your microwave is vented outside is to examine its location. Microwaves that are vented outside are typically installed above the kitchen stove. If your microwave is located in this position, it is more likely to be vented outside.

2. Inspect the Back of Your Microwave

Look for any visible exhaust ducts or venting features at the back of your microwave. Vented microwaves will have an exhaust duct that is connected to an exterior vent. If you see a vent at the back of your microwave, it is an indication that it is vented outside.

3. Look for Venting Options on the Control Panel

Some microwaves have control panel options related to venting. Check if your microwave has settings such as “Exhaust,” “Venting,” or “External Vent.” These options suggest that your microwave is vented outside rather than recirculating the air.

4. Check for External Venting Features

Take a closer look at the exterior of your microwave. Vented microwaves will have external components, such as an exhaust port or vent cover, which are used to expel the air outside. If you find these features, it is a strong indication that your microwave is vented outside.

5. Consider the Age and Model of Your Microwave

Newer models of microwaves are more likely to be designed for external venting as it is a more effective method of ventilation. Older models may not have this feature, so keep the age and model of your microwave in mind when determining if it is vented outside.

6. Consult the Owner’s Manual or Contact the Manufacturer

If you are still unsure whether your microwave is vented outside, refer to the owner’s manual or contact the manufacturer directly. They will be able to provide you with specific information about your microwave model and its venting options.

Venting your microwave outside helps improve air quality and eliminates cooking odors, making your kitchen a more pleasant space to work in.

Do Over-the-Range Microwaves Have to be Vented Outside

Does the microwave you want to install above your stove have to be vented?

No. OTR microwaves do not need to be vented outside. Basically, all microwaves come with venting at the top of the front of the microwave. This is so they work anywhere they are placed. According to GE, Over-the-Range microwaves do not need external venting. So don’t fret about venting your microwave, especially if it is a GE microwave. Many microwaves are recirculating (non-vented ductless).

Signs That Your Microwave is Vented Outside

If you’re uncertain whether your microwave is vented outside, here are a few indicators to help you determine:
