Step 2: Gather Your Tools

Tools:

measuring tape
circuit tester
coping saw
shims
nails
caulk
a plumber

Tip: For easy replacement, your new cooktop should be the same size or close to the same size as your old one.

Step 3: Prep the Area

Turn off the power source to the old cooktop at the fuse box and put a sign on the box saying ‘DO NOT TURN POWER ON!’ Double check wiring with a neon circuit tester to make sure lines are not hot.

Measure the opening from underneath and also the depth of the space. Remove old caulk and any trim or attachments. Disconnect the wires.

Tip: Label wires as you disconnect them to make reconnection easier.

Step 4: Install the Cooktop

Get a helper to assist you in removing the old cooktop. Measure the opening and the new cooktop again. If the new cooktop is larger than the old, enlarge the opening with a coping saw. If the new cooktkop is smaller than the old, add shims to the edges of the opening.

With your helper, drop in the new cooktop. Connect the wiring to a grounded junction box using an armored cable. Caulk edges if necessary and install trim.

If you’re unsure about the wiring, have a licensed electrician make the connections and test the cooktop to make sure it’s working properly.
