  • Socket wrench with extension: A socket wrench provides more torque than an adjustable wrench and can be used with different socket sizes to fit specific nuts and bolts. An extension allows you to reach into tight spaces.


  • Phillips head screwdriver: This screwdriver is used to tighten or loosen screws with a cross-shaped head.
  • Flathead screwdriver: A flathead screwdriver is used for screws with a straight slot in the head.

Mounting Brackets

  • Over-the-range microwave mounting brackets: These brackets are specifically designed to support the weight of the microwave and securely attach it to the cabinet above.

Other Materials

  • Electrical tape: Electrical tape is used to insulate and protect electrical connections.
  • Level: A level is used to ensure that the microwave is installed level and parallel to the floor.
  • Safety glasses: Safety glasses are essential to protect your eyes from flying debris or sparks during the installation process.
  • Gloves: Gloves can protect your hands from sharp edges or electrical components.

Step-by-Step Removal Process

Removing the old microwave requires careful steps to ensure safety and prevent damage to your kitchen. Here’s a detailed guide to safely remove your over-the-range microwave:

Before starting, ensure you have the necessary tools and safety gear. Turn off the power to the microwave at the circuit breaker and unplug it from the electrical outlet.

Disconnecting Utilities

Start by disconnecting the power cord and any gas line connected to the microwave. If your microwave is hardwired, you will need to turn off the power at the circuit breaker and hire a licensed electrician to disconnect the wiring.

Removing Mounting Screws

Locate the mounting screws that secure the microwave to the cabinet above. Using a screwdriver, carefully remove these screws and set them aside.

Gently Pulling Out the Microwave

Once the screws are removed, carefully pull the microwave straight out from the cabinet. Be cautious not to tilt or drop the microwave, as it can be heavy. Support the microwave with one hand while removing the screws with the other.

Lifting the Microwave Out

Lift the microwave up and out of the cabinet. If the microwave is particularly heavy, ask for assistance from a partner to avoid injury.

Setting the Microwave Down

Place the microwave on a stable surface, such as a countertop or the floor. Avoid placing it on an unstable surface or near the edge of a counter, as it could fall and cause damage.

With the old microwave removed, it’s time to install the new one. This process requires careful attention to detail and adherence to the manufacturer’s instructions.

Before beginning, ensure that the electrical wires are disconnected and the area is clear of any obstacles. Gather the necessary tools and materials, including a screwdriver, drill, mounting brackets, and screws.

Connecting Electrical Wires

Locate the electrical wires inside the cabinet and connect them to the corresponding terminals on the new microwave. Match the colors of the wires to ensure proper connections. Typically, black wires connect to black terminals, white wires to white terminals, and green or bare wires to ground terminals.

Mounting the Microwave

Align the mounting brackets with the holes in the back of the microwave and secure them using screws. Lift the microwave into place and slide it onto the brackets. Make sure it is level and fits snugly against the cabinet.

Securing the Microwave

Tighten the screws on the mounting brackets to secure the microwave in place. Use a level to ensure it is properly aligned and won’t tip or slide. Double-check all connections and tighten any loose screws.

Troubleshooting Tips

How to replace over the range microwave

Replacing an over-the-range microwave can generally be a straightforward process, but occasional hiccups can occur. Here are some common problems you may encounter and how to troubleshoot them:

Microwave Not Turning On, How to replace over the range microwave

  • Check the power supply:Ensure the microwave is plugged into a working outlet and the circuit breaker or fuse is not tripped.
  • Inspect the door switch:The door switch prevents the microwave from operating when the door is open. Check if the switch is faulty or misaligned.
  • Test the thermal fuse:The thermal fuse is a safety device that blows if the microwave overheats. If blown, it will need to be replaced.

Microwave Not Heating

  • Check the magnetron:The magnetron is the component that generates microwaves. If it’s faulty, the microwave won’t heat.
  • Inspect the waveguide:The waveguide is a metal tube that transmits microwaves from the magnetron to the cooking cavity. If it’s damaged or blocked, the microwave won’t heat.
  • Test the high-voltage capacitor:The high-voltage capacitor stores energy to power the magnetron. If it’s faulty, the microwave won’t heat.

Microwave Sparks or Arcs

  • Clean the cooking cavity:Food residue or grease buildup can cause sparks or arcs.
  • Check the stirrer:The stirrer helps distribute microwaves evenly. If it’s damaged or missing, sparks or arcs can occur.
  • Inspect the mica sheet:The mica sheet protects the waveguide from food particles. If it’s torn or damaged, sparks or arcs can happen.


Replacing an over-the-range microwave requires careful planning and execution. By following the steps Artikeld above, you can ensure a successful installation. Remember to prioritize safety and adhere to the manufacturer’s instructions. If you encounter any difficulties or have concerns, do not hesitate to seek professional assistance from a qualified electrician or appliance repair technician.
