How to install a wall oven
Replacing or adding a new wall oven in your kitchen? While it may seem outside of your comfort zone or even intimidating to take on this task on your own, you may be able to complete this installation yourself with the help of another person as well as some additional tools. Use this guide as an overview for how to install a wall oven.
Installing a wall oven: step-by-step instructions
When it comes to appliance installations, it’s important that you read your owner’s manual and installation instructions for full details and information that may not be covered with this guide. Check your local government ordinances and codes to ensure that you are allowed to proceed, and if you’re not familiar or comfortable working with electrical wiring, hiring a professional electrician is recommended.

Step 1: Prepare to install your wall oven
You’ll want to switch off the electrical supply from the fuse box before getting started. Use a non-contact electrical tester to make sure the power is shut off.
As you remove the oven from its packaging, place a piece of cardboard on the floor for the new oven to help minimize the chances of causing damage to your floor.
Step 2: Remove the old and new oven doors
If it’s an old oven that is being replaced, you’ll first want to remove the old oven door before removing the anchoring screws. If replacing a double oven, remove both doors before proceeding. With the help of a second person, carefully lift the oven from the cabinet and cut the electrical wiring.
Since ovens are heavy, you may want to remove the door to your new oven as well to make the installation process easier. Carefully place the door(s) handle side down on top of cardboard or a blanket.
Step 3: Measure the opening of the cabinet
Wall ovens, whether single or double, generally come in three different sizes–30-inch, 27-inch and 24-inch ovens. Measure the size of your cabinet to make sure that your oven will fit within the opening. Use your installation instruction for specific measurements.
If you’re cutting a new opening for your wall oven, make sure that you leave about ¼" of clearance on each side.
Step 4: Find junction box
A junction box should be located either 3" above or below the cabinet cutout. If you don’t see a junction box, it may be behind the wall. You will need to cut an opening in order to access the electrical wiring to complete the installation. Refer to your owner’s manual and installation instructions for full details.
Step 5: Place oven feet
Using the help of a second person, gently tilt the oven onto its back and place it on top of the cardboard so that you can attach the feet to the oven. How you attach the feet will depend on the height of your cabinet cutout, and the height of your cutout will depend on if you’re installing a single or double oven. Refer to your installation instructions for specific information and measurements.
Step 6: Make the electrical connection
Once you’ve placed the feet, stand the oven close to where it will be installed and connect the wiring per your installation instructions. Strip the wires from the electrical circuit and oven. Connect the wires with wire connectors using the corresponding colors – red, black, white and green or bare copper for the grounding wire.
For gas ovens:
Wrap the thread seal around the gas valve nipple and thread the gas valve coupler from the oven to the nipple and tighten with an adjustable wrench. Test all gas connections by brushing on an approved noncorrosive leak-detection solution (a mix of water and a few drops of dish soap in a spray bottle also works). If bubbles are found, there is a leak and you’ll need to tighten with the wrench. Once fully tightened, and no gas leaks are detected, plug the oven into the wall outlet.
Step 7: Complete oven installation
You’ll again want the help of a second person to assist in lifting the oven to its final installation spot. Secure the oven with the screws provided. If you removed the doors to make the installation process easier, reattach them along with any trimming provided.
Wall oven installation FAQs
Does a wall oven have to be in a cabinet?
Your wall oven will require room for the electronic parts as well as for the cooking cavity. For this reason, installing the wall oven will need to be done within a cabinet or a built-in wall.
Do you need an electrician to install a wall oven?
You may not need an electrician in order to complete the installation for your wall oven. However, if you don’t feel comfortable or are not familiar with the electrical wiring required to install the wall oven, it’s recommended that you hire an electrician.
Can I install a wall oven myself?
If you’re used to doing repairs and installations around your home, then installing a wall oven can be completed in one afternoon with the help of a friend. However, if you’re not very familiar with installing appliances or working with electrical wiring, then hiring a professional may be your safest bet.
