Turn off the power at the breaker
Before beginning to uninstall an electric cooktop, it is crucial to ensure your safety by turning off the power at the breaker. This step will prevent any accidents or electrical hazards during the removal process. Here is a detailed guide on how to safely turn off the power at the breaker:
Locate your home's electrical panel: Find the electrical panel in your home, which is usually located near the circuit breaker box. This panel houses all the switches that control the power supply to various areas of your home.
Identify the dedicated breaker switch for the electric cooktop: Inside the electrical panel, look for a double switch that is specifically labelled for the electric cooktop. It is important to note that the cooktop should have its own dedicated set of breakers, ensuring that turning off these breakers will not affect the power supply to other appliances or outlets.
Turn off the breaker switch: Once you have located the correct breaker switch for the electric cooktop, proceed to turn it off. Depending on the type of breaker switch, you may need to flip a toggle switch or push a button to the "off" position. Make sure that both breakers in the coupled set are turned off simultaneously.
Verify that the power is off: To ensure your safety, it is essential to confirm that the power to the electric cooktop is indeed turned off. You can use an electrical voltage detector to check for any active electrical voltage in the wiring. Attach the detector to the wiring in the electrical connection box, which is typically located underneath the cooktop.
Disconnect the wiring: After confirming that the power is off, proceed to disconnect the wiring. Remove the cover from the electrical connection box by unscrewing it with a screwdriver. Then, carefully remove the wire nuts from all connections, separating the wires to prevent any contact with each other or any metal surfaces.
By following these steps, you can safely turn off the power at the breaker and disconnect the wiring for your electric cooktop. Remember to always prioritize safety when working with electrical appliances, and if you are unsure or uncomfortable with any part of the process, consider seeking professional assistance.

Remove the cooktop's electrical connection
Before beginning any work on your electric cooktop, it is important to ensure that the appliance is not connected to a power source. Start by opening your home's electrical panel and locating the switch for the electric cooktop. The breaker switch will be a double switch dedicated solely to the cooktop and should be appropriately labelled. Push the switch to the off position to ensure that the power is cut.
Now, you can begin to work on removing the electrical connection. Open the cabinet doors beneath the cooktop and locate the electrical connection box attached to the bottom of the appliance. Use a screwdriver to remove the screw that holds the cover to the electrical connection box in place. Once the screw has been removed, carefully take off the cover.
Attach an electrical voltage detector to check that there is no active electrical voltage in the wiring in the box. This is an important safety step to ensure that you do not accidentally come into contact with a live wire. Once you have confirmed that the power is off, you can proceed to the next step.
Remove the wire nuts from all connections in the box. Typically, there will 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. Carefully pull the power feed wires through the entry hole, being mindful not to let them touch any metal surfaces during the removal process.
At this stage, the electrical connection to the cooktop has been successfully removed. You can now proceed with the rest of the cooktop removal process, which may involve removing brackets, cutting caulking, and lifting the cooktop out of the countertop. Remember to always exercise caution when working with electrical appliances, and if you are unsure about any part of the process, it is best to consult a qualified technician.

Remove the cooktop's hold-downs
Before beginning any work on your electric cooktop, ensure that it is unplugged and that there is no power going to the stove. You can do this by locating your electrical panel and finding the switch for the electric cooktop. Push the breaker switch to the off position.
Now, you can begin to remove the cooktop hold-downs. First, open the cabinet doors below the cooktop and 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 cover is removed, you can detach the electrical wires. There should be three groupings of wires: one white set and two colored sets, usually black and red, or black and black. Remove the wire nuts from all connections in the box and separate the wires, ensuring they do not touch each other or any metal surface. Next, carefully remove the power feed wires from the box by pulling them through the entry hole, again being careful not to touch any metal surface.
With the electrical connections detached, you can now focus on the physical hold-downs that secure the cooktop in place. Check under the counter for brackets holding the cooktop in place. If there are brackets, use a screwdriver to loosen the screws and remove them. If there is caulking on the edge of the cooktop, use a razor knife to cut through it. Now, slide a putty knife under the edge of the cooktop to gently lift it until you can get your fingers under it.
If your cooktop is a glass model, there may be additional steps. There are often two Phillips-head screws holding the cooktop to the stove frame, which can be removed with a Phillips-head screwdriver. If the burners are attached to the cooktop, you may need to use a sturdy prop to hold the front of the cooktop away from the stove frame while you work. Be very careful with glass cooktops, as broken glass or ceramic can be sharp.

Cut through any caulking with a razor knife
Before you start removing an old electric cooktop, it's important to cut through any caulking that may be present. This can be done effectively with a razor knife, also known as a utility knife.
To begin, locate the caulking on the edge of the cooktop. Take your razor knife and carefully cut through the caulking, ensuring that you don't cut too deeply and damage the underlying surface. It's important to hold the knife at a shallow angle to avoid scratching the surface. You can also use a putty knife to cut or scrape away any excess dried caulk.
When cutting through the caulking, it's recommended to use a sharp blade. A dull blade may not cut effectively and can lead to uneven results. Additionally, always cut the caulking at a 45-degree angle to achieve a smooth finish. This will help you create a clean and precise line.
For removing caulking, you can also consider using a flexible or rigid scraper blade. These blades are designed to remove caulk and can be effective in ensuring that the surface is not scratched. There are various types of blades available, such as the BOSCH OSC214C 1-inch x 2-inch Caulk Knife Blade, which has been praised for its effectiveness in removing old caulk from windows and other surfaces.
By following these steps and using the right tools, you can successfully cut through any caulking with a razor knife, making it easier to remove your old electric cooktop.

They may be secured with screws or clips, depending on the make and model of your cooktop. Using a screwdriver or a wrench, loosen the screws or remove the clips that hold the mounting brackets in place. Take note of the number and location of the brackets, as you will need to reinstall them later if you're simply replacing the cooktop.
By loosening the mounting brackets, you are preparing the cooktop for removal. This step ensures that the cooktop is no longer securely attached, making it easier to lift and remove. Once the mounting brackets are loosened or removed, you can gently lift the cooktop a few inches to ensure that it is loose from the counter. Be cautious, as there may still be electrical connections or other attachments that need to be disconnected.
If your cooktop is attached to your countertops with brackets, you may need to completely unscrew and remove the brackets to release the cooktop. With the help of one or more people, push the cooktop from the bottom to lift it up and out. Typically, cooktops require 30 inches and a few inches of clearance on each side, but these measurements may vary, so refer to your product manual for specific dimensions.
