Replacing a cooktop can be a daunting task, but with the right instructions it can be done relatively easily. The first step is to shut off the power to the cooktop at the breaker box. Once the power is off, you can remove the knobs and screws that hold the cooktop in place. Next, you'll need to disconnect the power and gas lines, then lift up and remove the old cooktop. Finally, you'll install the new cooktop by connecting the power and gas lines, replacing the screws and knobs, and turning on the power.
