Step 2: Gather Your Materials and Tools

Upgrade your kitchen by replacing a conventional electric cooktop with a new ceramic unit.

Materials and Tools:
measuring tape
neon circuit tester
jigsaw
shims
silicone sealant
double-sided adhesive tape

Safety Tips:

  • Make sure your countertop is bonded with a heat resistant (212F/100F) adhesive to prevent distortion.
  • For fire safety, do not install a ceramic cooktop between two tall cabinets.
  • Maintain a minimum distance of 2 inches between the cooktop and the wall.
  • Flammable objects should be at least 30 inches above the cooktop.
  • Do not install the cooktop above another heat-producing appliance.

Step 3: Prep the Area

Turn off the power source to the old cooktop at the fuse box and put a sign on the fuse box saying 'DO NOT TURN POWER ON!'

Start by measuring the opening from underneath the existing cooktop; also measure the depth of available space. Your new cooktop should be the same size or close to the same size as your current cooktop.

Double check with a neon circuit tester to make sure power is off to the old cooktop.

Remove old caulk and any attachments.

Disconnect wiring, paying close attention to how old cooktop is wired. New wiring goes in the way old wiring goes out; label wires to make reconnection easier.

Step 4: Remove the Old Cooktop

Get someone to help you lift the old cooktop out of the opening.

If the new cooktop is larger than the old, enlarge the opening with a coping saw. If the new cooktop is smaller, add shims to the opening, screwing them into the sides of the under-counter.

Seal cut edges with heat-resistant sealant to avoid swelling.

Step 5: Install the New Cooktop

Now it's time to install the spring clips. Hang spring clips from the upper edge of the cutout and secure them with screws. For granite countertops, secure spring clips with double-sided adhesive tape rather than screws and coat edges with silicone sealant.

With the power still OFF, feed the power cord through the opening and connect the new cooktop to the power supply.

Position the new cooktop on spring clips and press down until it clicks into place. The cooktop should sit tightly on the countertop.

Turn the power back on.

Tip: Do not permanently seal the new cooktop to the countertop; this could cause damage.
