Electric cooktop installation or replacement of an existing cooktop is a task you can perform yourself. However it could be very risky. This is because the Appliance has some complex electrical circuit connections. In the other hand, the machine is an expensive appliance and damaging any part could cost a fortune.
If you choose to replace your cooktop yourself, then you will have to pay attention to my instructions otherwise call an electrician.
Turn off power and remove the old cook top:
Make sure you read the manual guide properly. Endeavor to follow all the instructions. Shut of all power supply to the appliance and confirm by using a voltage tester. Carefully disconnect the wires attached to the cooktop hardware components, unscrew the bolts. Keep in mind the order you performed these operations and the spots you disengaged each component since you will do the same when installing the new cooktop
Compare the Amperage and Voltage of the old cooktop to the new:
Don’t make the mistake of purchasing a new cooktop, which has a size bigger than the dimensions of the counter. Else you will have to change the counter or make a complex adjustment.
Also determine the Amperage ratings. Latest cooktop has 40-A rating. If your old cooktop is 30-A or less then you will need to adjust your circuit voltage.
The recommended voltage supply for a 40-A rating and above is 240-Volts junction boxes or wires. Therefore, at this stage you need an electrician to upgrade before you proceed.
Make Adjustment and transfer clips to the new cooktop:
In situation where the new cooktop is slightly bigger than the old hole, you can cut across the edges of the counter to increase the hole to fit the cooktop. Whereas if the hole is slightly is slightly bigger, attach some flat metal bars to get the required measurement.
Screw the clips detached from the old cooktop in place. In case of granite counter, instead of bolts you will need to hold the clip with adhesives.
Carefully lower the cooktop into the hole:
Lift gently and drop the cooktop into the hole, check the device’s manual to see if you are leaving anything undone. If not, then connect the wires, burners or any other components just the way you detached them from the old cooktop.
Turn on power and Test your cooktop:
After all connection, tightening all bolts and fixing back the wire nuts in place. Tidy any debris from the region around the counter. Now you are set test to test your newly installed cooktop.
Turn on the power supply and continue using the cooktop.
NOTE: the DIY installation processes could be dangerous. You are advised to use proper tools, ensure safety precautions and follow all instructions.
