Installing a wall oven: step-by-step instructions

This guide will provide you with a step-by-step overview of how to install a wall oven. Installing your new oven shouldn't take more than a few hours with the help of another person but remember that you should reference your installation instructions for full details and specific measurements you'll need.

What you’ll need for wall oven installation

SUPPLIES

  • Cardboard 

  • Installation instructions 

  • Wire connectors

  • Thread sealant (if installing a gas oven) 

Tools

  • Phillips screwdriver

  • Non-contact electrical tester 

  • Measuring tape 

  • Drill 

  • 1-inch drill bit 

  • Level 

  • Flat-blade screwdriver

Ruler

STEP 1: MEASURE THE SPACE OF THE CABINET OPENING

Measure the opening of your cabinet as well as the oven itself to make sure that you have the required space clearance to complete the installation. Standard wall oven sizes typically come in widths of 24, 27, and 30 inches, with heights varying if it's a single, double or combination oven. Reference your installation instructions to determine the exact measurements you'll need. If you’re cutting a new opening for your wall oven, make sure that you leave about ¼" of clearance on each side.

Disconnecting electricity

STEP 2: TURN OFF ELECTRICITY

Switch off the electricity at the fuse box before beginning the installation. Make sure that the power has been completely turned off by using a non-contact electrical tester.

Box

STEP 3: PREP AREA WHERE THE WALL OVEN WILL BE INSTALLED

Carefully remove the new oven from its packaging and use either the flattened box it came in or a blanket to place the new oven near the installation spot. Placing it on top of the box or blanket will help reduce the chances of damaging your floors.

STEP 4: REMOVE DOORS OF THE EXISTING AND NEW OVENS

Remove the door from the existing oven, if there is one. If removing a combination or double oven, you'll want to remove both sets of doors. Do the same with the new oven as well to make lifting and positioning the oven easier. Place the door or doors handle-side down on a piece of cardboard or blanket.

Screwdriver

STEP 5: REMOVE ANCHORING SCREWS OF EXISTING WALL OVEN

Loosen the anchoring screws present while the second person supports the weight of the oven. Carefully remove the oven from the cabinet opening and cut the electrical wiring connecting the oven to the junction box.

Junction box

STEP 6: LOCATE JUNCTION BOX

The junction box should be either 3 inches above or below the cabinet cutout. If you don't see a junction box, then it may be behind the drywall of the cutout and you'll have to cut an opening to reach the box and connect the wiring.

Oven feet

STEP 7: PLACE OVEN FEET

Tilt the new oven onto its back carefully with the help of a second person, making sure to place it on the cardboard to help avoid damage. Use your installation instructions for specifics, since how you attach the feet will depend on the height of your cutout, as well as if you're installing a single or double oven.

Electrical connection

STEP 8: COMPLETE ELECTRICAL CONNECTION

Again, using your installation guide for specifics on how to connect the wiring, strip the wires from the junction box and the oven. Using wire connectors, connect each wire to each of the corresponding colors—typically red, white and black with green or bare copper corresponding to the grounding wire. 

 

If installing a gas oven: Use thread sealant and brush onto the gas nipple, thread the gas valve coupler from the oven to the nipple and adjust with an adjustable wrench. With either an approved, non-corrosive leak-detection solution or with water and soap mixed into a spray bottle, check to make sure that the gas line is tightly sealed. Turn the gas line back on, and if you see large bubbles, it means that the gas line has a leak, and you'll need to tighten it. If no bubbles appear, connect the oven into a wall outlet.

Double wall oven

STEP 9: FINISH THE INSTALLATION

Lift the oven into the opening of your cabinet with the help of a second person to distribute the weight of the oven. Secure the anchoring screws so that the oven stays in place, and reattach the oven doors along with any trimming.

Wall oven installation FAQs

Does a wall oven have to be in a cabinet?

You will need a cabinet or a built-in wall in order to install a wall oven, since it requires room for the cooking cavity and electronic parts of the oven.

Do you need an electrician to install a wall oven?

Whether or not you need an electrician depends on how comfortable you feel with installations that require working with electricity. If this is something that you haven't done before or if you're unfamiliar with working with electrical wiring, then hiring an electrician is strongly recommended.

How much does it cost to install a wall oven?

Oven prices vary greatly depending on brand, model and whether it's a single, double or combination oven. However, prices for Maytag® wall ovens can generally range anywhere from $1000 to $3000. Cost of installation may depend on the complexity of the installation as well as your home's location.

Can I install a wall oven myself?

You should only take on the task of installing your wall oven if you have at least some experience installing other appliances or working with electrical wiring. If you don't have experience with either, then it may be best to hire a professional to complete the installation.
