Frequently Asked Questions About Over-the-Range Microwave Installation?
What height above the range should I mount my over-the-range microwave?
The standard and generally recommended height for mounting an over-the-range microwave is 30 inches between the cooktop surface and the bottom of the microwave. This provides sufficient space for cooking while also allowing comfortable access to both the microwave and the range.
While 30 inches is the common recommendation, it’s essential to consult both the microwave manufacturer’s installation instructions and your local building codes. Some manufacturers specify a minimum and maximum range for the mounting height, and these should always be prioritized. Ignoring these specifications can lead to poor ventilation, overheating, or even voiding the warranty. Also, consider the height of the tallest pot you typically use on your stove. You want to ensure enough clearance so that steam and heat are adequately ventilated and your cookware doesn’t accidentally bump into the microwave. Furthermore, consider the primary users of the microwave. If you are particularly tall or short, you might want to adjust the height slightly to better suit your ergonomic needs. A slightly higher mounting may be preferable for taller individuals to prevent stooping, while a lower mounting (within the manufacturer’s guidelines) could be more accessible for shorter users. The key is to strike a balance between functionality, safety, and personal comfort. Remember that altering the height too much can impact the microwave’s ventilation efficiency, especially if it doubles as a range hood.
How do I vent an over-the-range microwave, and what are my venting options?
Venting an over-the-range microwave involves directing the steam, smoke, and odors produced during cooking either outside your home or back into the kitchen. Your venting options include recirculating (ductless), venting through the wall, or venting through the roof. The installation process and required components vary depending on your chosen method, but generally involves connecting the microwave’s exhaust fan to existing ductwork or setting up a filtration system.
Successfully venting your microwave depends on your kitchen’s existing ductwork and your home’s construction. Recirculating microwaves are the simplest to install as they don’t require external ducting. Instead, they use a charcoal filter to clean the air before recirculating it back into the kitchen. While easy to set up, they are less effective at removing moisture and strong odors compared to ducted options and the filters need regular replacement. Venting through the wall involves connecting the microwave’s exhaust vent to ductwork that leads directly outside through an exterior wall. Venting through the roof is similar, but the ductwork extends upwards to an opening in the roof. These external venting options offer superior performance in removing pollutants but require more extensive installation, potentially involving cutting through walls or roofing and connecting ductwork properly to prevent leaks. Before starting the installation, identify which venting option is best for your kitchen layout and capabilities. Check your local building codes for any specific requirements. Many microwaves can be configured for different venting directions (rear, top, etc.) depending on your ductwork, but you will have to reconfigure the fan and follow the manufacturer’s instructions for converting the microwave from recirculating to a ducted setup if necessary. If you’re not comfortable working with ductwork, electrical connections, or cutting into walls, it’s best to hire a qualified professional for proper and safe installation.
What’s the best way to find the studs behind my wall for mounting?
The most reliable way to find studs is by using a stud finder. These devices, available in both magnetic and electronic versions, detect changes in density behind the drywall, indicating the presence of a stud. Alternatively, you can use the “knock test,” listen for a solid sound rather than a hollow one, or look for visual cues like nail pops or outlets, which are usually attached to studs.
More specifically, an electronic stud finder is generally the most accurate and efficient method. Start by calibrating the stud finder according to the manufacturer’s instructions, typically by holding it flat against the wall and pressing a button. Then, slowly move the stud finder horizontally across the wall. When the device indicates it has found a stud (usually with a light or sound), mark the spot. Repeat the process a few inches to either side to confirm the stud’s location and determine its width. Remember that studs are typically spaced 16 or 24 inches apart on center, so knowing the location of one stud can help you find others. If you’re using the “knock test,” gently tap along the wall. A hollow sound indicates empty space between studs, while a solid, less resonant sound suggests you’ve found a stud. To further verify the stud’s position, use a small nail or awl to carefully probe the wall at the suspected location. If you hit solid wood, you’ve likely found a stud. Remember to patch any small holes you make. When hanging a heavy appliance like an over-the-range microwave, accurate stud location is critical for ensuring secure mounting and preventing the appliance from falling.
How do I adapt my existing cabinetry to fit the new microwave?
Adapting existing cabinetry for a new over-the-range (OTR) microwave often involves modifying the cabinet’s bottom to ensure proper clearance and mounting. This typically includes cutting a larger opening, adding filler strips or shims for support, and verifying the electrical outlet is accessible and properly positioned for the new microwave.
The specific modifications needed depend heavily on the dimensions of your new microwave compared to the old one and the existing cabinet configuration. Begin by carefully measuring the dimensions of both the microwave and the space between your cabinets. Pay close attention to the mounting bracket placement specified in the new microwave’s installation manual. If the new microwave is larger, you might need to cut into the bottom of the cabinets. A jigsaw with a clean-cutting blade is usually best for this, but always prioritize safety by wearing eye protection and using appropriate supports to prevent the cabinet from splintering. Use painter’s tape to mark your cut lines clearly and prevent chipping. If the new microwave is smaller or has a different mounting bracket location, you might need to add filler strips or shims to the bottom of the cabinets. These can be made from wood that matches or complements your existing cabinetry. Secure these fillers with wood glue and screws, ensuring they are flush with the cabinet bottom to provide a stable mounting surface. Finally, double-check that the electrical outlet is within easy reach of the microwave’s power cord. If not, you may need to consult with a qualified electrician to relocate or add an outlet.
What if my existing range hood was hardwired; how do I handle the electrical?
If your existing range hood is hardwired, you’ll need to disconnect the electrical supply safely before installing the over-the-range microwave and then properly reconnect it, potentially adapting the wiring to suit the microwave’s plug-in requirements, and you MUST follow all local electrical codes and safety regulations.
Before you even think about touching any wires, **turn off the breaker** that controls the circuit for the range hood. Double-check with a non-contact voltage tester to ensure the power is truly off. Once you’ve confirmed the power is off, carefully disconnect the wiring from the existing range hood. Note how the wires are connected – typically black (hot), white (neutral), and green or bare copper (ground). Take a picture or draw a diagram to help you remember the configuration.
Since over-the-range microwaves typically plug into a standard outlet, you’ll likely need to install an outlet box in the cabinet above the microwave location. This usually involves running a new wire from the existing hardwired connection to the new outlet box. It’s strongly recommended to use the same gauge wire as the existing wiring. Connect the black, white, and ground wires to the corresponding terminals on the new outlet. Secure the wire properly within the outlet box and install the outlet itself. Alternatively, if the microwave’s cord can reach the existing hardwired location, an electrician can install a junction box and outlet directly at that point.
Safety is paramount. If you are not comfortable working with electrical wiring, hire a qualified electrician. Improper wiring can lead to fire hazards or electric shock. Ensure all connections are secure and properly insulated. Furthermore, verify your microwave’s electrical requirements (voltage, amperage) and ensure the existing circuit can handle the load. Using an undersized circuit can overload the breaker and cause problems. After installation, test the microwave and the circuit breaker to confirm everything is working correctly.
How much does professional over-the-range microwave installation typically cost?
Professional over-the-range microwave installation typically ranges from $150 to $500. This cost includes the removal of an existing microwave (if applicable), mounting the new microwave, connecting it to the existing electrical outlet, and ensuring proper ventilation.
Factors influencing the final cost include the complexity of the installation. For instance, if electrical work is required, such as installing a new outlet or upgrading the circuit, the price will increase. Similarly, if modifications to the cabinetry or ventilation system are necessary (e.g., cutting into a cabinet or rerouting ductwork), labor costs will be higher. The geographic location and the specific installer’s rates also play a role in determining the final price. It’s always advisable to obtain quotes from several qualified installers to compare prices and services offered. Be sure to clarify what is included in the quoted price, specifically addressing whether it covers the removal of the old microwave, any necessary electrical work, or modifications to surrounding cabinetry. Ask if there are extra charges for things like hauling away your old microwave. A detailed quote will help you avoid unexpected costs and ensure a smooth installation process.
