Induction Cooktop Problems and Solutions

Induction Cooktop Heating Issues

Heating issues are among the most common problems with induction cooktops. Here are some practical solutions for induction cooktop heating problems.

Induction Cooktop Not Heating Properly

When your induction cooktop isn’t heating properly, check these issues.

Check Your Cookware for Induction Cooktop Compatibility

When your induction cooktop isn’t heating as it should, first ensure your cookware is induction-compatible.

Only cookware with a magnetic base works on these cooktops. Test the cookware that you’re using with a magnet. If the magnet sticks to the bottom of the cookware, then the pot or pan is induction-compatible.

If a magnet doesn’t stick the bottom of your cookware, buy new pots and pans that are induction-compatible.

Dirty Induction Cooktop or Cookware

If your cookware is induction-compatible and not heating properly, check for any obstructions like crumbs, caramelized sugar or debris between the cookware and the cooktop surface. If the cooktop surface is dirty, clean it as shown in this helpful YouTube video:

Clean the bottoms of your pots and pans thoroughly. A build-up of deposits on the bottom of cookware can inhibit heating.

If the heating problems persist in your induction cooktop, there may be a failure within the cooktop. Schedule cooktop repair service to have a Sears Home Services technician diagnose and repair the issue.

Induction Cooktop Not Heating at All

Check these issues to resolve a problem with your induction cooktop not heating at all.

Control Panel Lock Feature Engaged

Many induction cooktops come with a child lock or safety lock feature. When activated, this setting can prevent the appliance from functioning.

Consult the user manual to locate the lock/unlock controls. Holding down the appropriate button for a few seconds will disable the control lock on many induction cooktops.

Cookware Incompatibility

Induction cooktops use electromagnetic fields to directly heat compatible cookware.

When your cooktop isn’t heating at all, check that your cookware is induction-compatible as mentioned in the section above. Aluminum cookware won’t heat at all on an induction cooktop unless it has a layer of magnetic metal embedded in its bottom.

If necessary, buy cookware that’s clearly marked as "induction-ready."

Induction-Compatible Cookware Not Properly Positioned

Induction cooktops only heat when the cookware is correctly placed within the designated cooking zone. A misaligned pan may not activate the electromagnetic field.

Center the cookware over the marked cooking area. Ensure the base of the cookware is flat and large enough to engage the cooktop’s sensors.

Electrical Power Supply Issues

A faulty power supply or a tripped circuit breaker can prevent the cooktop from working altogether.

• Make sure that the cooktop power cord is securely plugged in to the electrical outlet.
• Check your home’s electrical panel for tripped circuit breakers and reset them if necessary.
• If the problem persists, have a service technician or electrician use a multimeter to test the outlet's voltage and ensure it matches the cooktop’s specifications.

Internal Cooktop Component Failure

Issues like a defective induction coil, a faulty control board, or damaged sensors could prevent the cooktop from functioning.

When you suspect an internal failure, schedule range repair service to have a technician diagnose and fix the heating failure.

Cooking Temperature Fluctuations

Temperature fluctuations can result from an insufficient electrical power supply.

Have an electrician check the voltage and current going to your induction cooktop when the appliance won’t heat consistently.

Uneven Heat Distribution

Uneven heating can occur if the cookware isn’t centered on the cooking zone.

Ensure the cookware is properly aligned with the markings on the cooktop surface.

Also, check if the cookware is flat and has a smooth base. If the base is warped, you’ll likely need to replace the pot or pan.

If these solutions don’t resolve your heating issues, schedule appliance repair to have a Sears Home Services technician diagnose and fix uneven heat distribution problems.

Unexpected Noises

Unexpected noises from your induction cooktop can be unsettling. Here’s how to identify and resolve some common noise issues:

• Buzzing or humming sounds: Loose or faulty wiring can cause buzzing or humming sounds. Turn off the cooktop and unplug it. Inspect an accessible wiring connections and tighten any loose wires. If the noise persists, schedule service to have a professional technician find the source of the buzzing noise and fix it.
• Clicking or popping noises: These noises often result from the expansion and contraction of the cooktop's components due to temperature changes. This is usually normal. However, if the noises become loud, excessive or are accompanied by malfunctions, have the cooktop inspected and serviced by a technician.
• Fan or cooling system noises: Induction cooktops usually have a built-in fan to prevent overheating. If you hear unusual noises like rattling or grinding, unplug the cooktop or range and check if the fan or cooling vents are blocked. If the noises persist, schedule professional help to diagnose and resolve the issue.

Induction Cooktop Control Panel Issues

Control panel problems can be particularly frustrating. Here are some common issues and their solutions:

Unresponsive Touch Controls

When the touch controls aren’t responding, check to see if the control panel is locked. Follow the instructions in your owner’s manual to unlock the cooktop. This typically involves pressing and holding a designated lock/unlock button down for 5 deliberate seconds.

Ensure the control panel is clean and free from dirt or residue. Wipe the surface gently with a soft, damp cloth.

If these tips don’t work, try turning off the cooktop at the circuit breaker for a few minutes and then turning it back on. This can sometimes reset the touch controls.

Error Codes

Error codes indicate specific issues. Refer to your cooktop’s user manual to understand the error code displayed on the control panel.

The error code could be caused by a simple user error.

If you see a code not addressed in the owner’s manual, the code could be caused by a more complex issue.

You can look up common induction cooktop error codes and find troubleshooting solutions on our Cooktop Error Code Charts.

Follow the troubleshooting tips for the code or schedule cooktop repair service if you’re unable to safely resolve the problem on your own.

Calibrating the Control Panel

Some induction cooktops allow you to calibrate cooktop settings for accurate temperature control.

Follow the instructions in your user manual carefully to perform this calibration. This can help resolve issues related to temperature inaccuracies or inconsistent heating.

If these solutions don’t resolve your control panel issues, schedule professional appliance repair by Sears Home Services for a thorough diagnosis and fix.
