Understanding Over-the-range Microwaves
Before you start, it’s important to know what makes over-the-range microwaves different. These appliances are designed to hang above your stove, doubling as a light and vent for your cooktop.
Key Features
- Built-in exhaust fan: Helps remove smoke, odors, and steam from cooking.
- Cooktop lighting: Illuminates the stove below for better visibility.
- Space-saving design: Frees up countertop space.
- Multiple venting options: Can vent outside or recirculate air inside.
Typical Dimensions
Most over-the-range microwaves are about 30 inches wide to match standard stove widths. Heights and depths vary, but depth is usually around 15–16 inches. Always check your stove and cabinet measurements before buying.
Weight Considerations
These microwaves weigh between 50–75 pounds. You’ll need sturdy support and possibly help from another person during installation.
Planning Your Installation
Mounting a microwave over the stove is not just a one-step process. Careful planning ensures safety and performance.
Measuring Your Space
Start by measuring the space above your stove. Record:
- Width: The distance between cabinets, usually 30 inches for standard stoves.
- Height: Minimum clearance from stove to microwave is usually 13–16 inches (check your microwave’s manual for the exact requirement).
- Depth: Make sure the microwave doesn’t stick out too far, blocking cabinet doors or creating a hazard.
Checking Cabinet Structure
The upper cabinet above your stove will support the microwave. It must be strong enough to hold the unit’s weight. If the cabinet is flimsy or damaged, reinforce it or replace it before starting.
Electrical Requirements
Most over-the-range microwaves need a dedicated 120V outlet. This outlet should be inside the upper cabinet, not behind the microwave. If you don’t have one, you’ll need to add it—either yourself (if you know electrical work) or with a licensed electrician.
Ventilation Options
There are two main ways to vent:
- External venting: Air is sent outside through ductwork.
- Recirculating venting: Air passes through filters and returns to the kitchen.
External venting is better for removing smoke and odors, but requires ductwork. Recirculating is easier for kitchens without exterior walls nearby.
Choosing The Right Microwave
Not all microwaves can be mounted over the stove. You need a model made specifically for this purpose.
Important Features To Consider
- Size and fit: Match your microwave’s width to your stove (usually 30 inches).
- Vent type: Choose between external and recirculating venting.
- Fan power: Look for at least 300 CFM (cubic feet per minute) for good ventilation.
- Lighting: Check the brightness and bulb type.
- Control panel placement: Make sure buttons are easy to reach.
