Turn off the power at the circuit breaker
Before you begin to disconnect your electric cooktop, it is important to turn off the power at the circuit breaker. This is a crucial safety step that will ensure that there is no risk of electric shock or other hazards during the disconnection process. Here is a step-by-step guide to help you turn off the power at the circuit breaker:
Locate the Circuit Breaker:
First, you need to find your home's electrical panel, which is usually located in the basement, garage, or a closet. Once you have located the electrical panel, open it to access the circuit breakers. The circuit breaker for your electric cooktop should be clearly labelled, and it will likely be a double switch dedicated solely to the cooktop.
Turn Off the Power:
Once you have identified the correct circuit breaker, it's time to turn off the power. Push the switch to the "off" position. In some cases, there may be two coupled breakers, and pushing one switch to the off position will turn off both breakers simultaneously. This step ensures that electricity is no longer flowing to your electric cooktop, making it safe to work on.
Verify Power Disconnection:
To ensure your safety, it is essential to verify that the power is indeed off. You can use an electric tester or voltage detector to check that there is no active electrical voltage in the wiring. This step may be especially important if the circuit breaker is not clearly labelled, as you can double-check that you have turned off the correct breaker.
Safety Precautions:
Working with electricity can be dangerous, so it is crucial to take the necessary safety precautions. Before proceeding with the disconnection of your electric cooktop, make sure you are wearing appropriate protective gear, such as insulated gloves and safety goggles. Additionally, ensure that you are working in a dry area to prevent any risk of electric shock.
Disconnecting the Cooktop:
After confirming that the power is off, you can proceed with the next steps of disconnecting your electric cooktop. This may involve removing the electrical connection box cover, detaching wires, and carefully lifting the cooktop out of its hole in the countertop. Always refer to the manufacturer's instructions or seek professional guidance if you are unsure about any part of the process.

Remove the electrical connection box cover
To remove the electrical connection box cover, first, open the cabinet doors below the cooktop. You should then be able to locate the electrical connection box attached to the bottom of the cooktop. Use a screwdriver to remove the screw that holds the cover to the electrical connection box in place. Once the screw has been removed, you can take off the cover.
Before proceeding, it is important to ensure there is no active electrical voltage in the wiring in the box. To do this, attach an electrical voltage detector. Check that there is no power in the wiring.
You can then begin to remove the wire nuts from all connections in the box. There should be three groupings of wires: one white set, and two coloured sets, usually black and red, or black and black. Once the wire nuts have been removed, separate the wires to ensure they are not touching each other or any metal surface.
Finally, remove the power feed wires from the box. These are the wires that are coming into the box from an external source, not from the cooktop itself. When removing the wires from the box, pull them through the entry hole carefully, being careful not to touch the wires to any metal surface.

Check for active electrical voltage
Before beginning any work on your electric cooktop, it is imperative that you check for active electrical voltage to ensure your safety and avoid the risk of electric shock or damage to the appliance. Here are the steps you should follow:
- Turn Off the Power: Locate the circuit breaker that controls the power to your electric cooktop. It is typically found in the main service panel of your home. Make sure to flip the breaker switch to the "off" position. This step is crucial as it ensures that no electricity flows to the cooktop during the disconnection process.
- Verify the Power Status: To ensure that the power is indeed off, you can use a voltage tester or a non-contact voltage detector. These tools are essential for your safety and can be purchased at most hardware stores. A voltage tester will have two probes, one at each end, while a non-contact voltage detector is a handheld device that emits a warning signal when it detects voltage.
- Access the Cooktop Wiring: Remove the electric cooktop's control knobs and backguard (if applicable) to access the wiring. This will expose the wiring and electrical connections behind the cooktop. Be sure to refer to your cooktop's user manual for specific instructions on how to safely remove these components.
- Test for Voltage: With your voltage tester or non-contact voltage detector, check each wire terminal to ensure that no power is running to the cooktop. Touch one probe of the voltage tester to each terminal, or simply hold the non-contact voltage detector near each terminal. If the tester lights up or the detector signals a warning, the circuit is still live, and you should double-check the circuit breaker and ensure that no other power source is active.
- Double-Check the Outlet: If your electric cooktop is plugged into an outlet, test the outlet for voltage as well. Unplug the cooktop and test the outlet with your voltage tester or non-contact voltage detector to ensure that no power is present.
- Safety First: It is crucial to remember that electricity can be extremely dangerous. Always exercise caution and never proceed if you are unsure about any aspect of the process. If you feel uncomfortable or lack the necessary tools, it is best to contact a qualified technician to assist you.
By following these steps, you can safely check for active electrical voltage and ensure that your electric cooktop is ready for further disconnection or maintenance work.

Remove wire nuts and separate wires
Before you begin to disconnect your electric cooktop, it is important to ensure safety. Open your home's electrical panel and find the switch for the electric cooktop. The breaker switch will be a double switch dedicated solely to the cooktop and should be labelled as such. Push the switch to the off position. Breakers are coupled, so both will go off at the same time.
Now, open the cabinet doors below the cooktop. You should be able to locate the electrical connection box attached to the bottom of the cooktop. Use a screwdriver to remove the screw that holds the cover to the electrical connection box in place. Remove the cover. Attach an electrical voltage detector to ensure there is no active electrical voltage in the wiring in the box.
Now, you can begin to remove the wire nuts from all connections in the box. There should be three groupings of wires: one white set and two coloured sets, usually black and red, or black and black. When the wire nuts are removed, separate the wires to ensure they are not touching each other or any metal surface.
Finally, remove the power feed wires from the box. These wires will be the ones coming into the box from an external source, not from the cooktop itself. When removing the wires from the box, pull them through the entry hole carefully, making sure not to touch the wires to any metal surface while removing them.
