Induction cooktops give you fast heating, they are energy efficient, and you can control the heating temperature with high accuracy. But even such appliances break down. The reasons for heating problems with an induction cooktop can be different: from a locked cooktop to a faulty burner.

Reasons Why the Induction Cooktop Has Heating Issues

Incompatible Cookware
For proper operation, an induction cooktop requires cookware with a ferromagnetic bottom, because these cooktops work on the principle of magnetic induction. Using unsuitable cookware will cause such results as: the cooktop will not turn on and therefore will not heat, or it will heat very weakly. Unsuitable cookware includes aluminum, glass, and copper pots. It is also very important that the bottom of the cookware is perfectly flat and even, without chips or heavy wear. All this reduces heating efficiency.
Solution
- Before using, make sure that the cookware is suitable for your cooktop, meaning that it is induction compatible.
- If you have a magnet at home, use it to check. If the magnet sticks to the bottom of the pot, the cookware is suitable.
- If the cookware does not pass the test, buy special pots and pans for induction cooktops.
Locked Cooktop
Sometimes owners of induction cooktops face this problem: the cooktop shows that the panel is locked, and as a result, the cookware does not heat. This happens because of the child lock function, an electronic failure, or the activation of protection from accidental touches. In this state, the cooktop may react to some commands, or it may be completely in “sleep” mode.
Solution
- Find the manufacturer’s manual and try to turn off the lock. Usually, you need to press a certain combination of buttons (different for each model) or hold down a specific button for several seconds.
- If the recommendation from step 1 did not help, most likely there is an electronic failure and professional diagnostics will be needed.
Faulty Induction Coil
The induction coil creates the magnetic field that produces heating in the cookware. It is called the “heart” of the cooktop. If it is burned out or damaged, the cooktop may completely stop heating the cookware, or it may heat only partially.
Solution
We recommend using qualified technicians for diagnostics and replacement of the coil. The danger of DIY repair is that the coil is connected to the high-voltage part.
Pro Tip:
Regular maintenance and cleaning of the inside of the cooktop can help prevent overheating and extend the coil’s service life.
Damaged Burner
Damage to a specific induction burner affects the work of certain heating zones on the cooktop, and they stop working. As a result, you may see no response when you turn it on or only weak heating.
Solution
In this case, replacement is needed, and the faulty burner must be replaced entirely. With special tools, technicians check the resistance and integrity of all heating zones and replace the damaged element directly.
Pro Tip:
Dropping heavy cookware on the cooktop can damage the burners. Try to avoid this to reduce the risk of damage.
Control Board Issues
The control board is responsible for all functions of the cooktop, including heating. Failures on the control board can cause heating to work incorrectly, indicators to blink, or some zones to stop working completely.
Solution
If the cause is the control board, it is usually replaced with a new one. Before that, the technician runs diagnostics of all connections to make sure other elements are working fine.
Pro Tip:
If you notice the first signs of issues (blinking display, unpredictable work), it’s better to call a specialist right away, without delaying the repair.

Can I use the cooktop if one burner isn’t working, or will it cause further damage?
Hi Ethan! You can use the cooktop, but only on the working zones. A malfunctioning burner may indicate issues with the coil or control board. Continuing to use it without repair can cause electronic failure or damage other zones.
Can spilled liquids cause heating problems?
Hi Hailey! Yes, spilled water or other liquids can get under the glass and cause a short circuit or trigger safety protection. If a spill occurs, immediately turn off the cooktop and dry the surface thoroughly. If liquid is suspected inside, call a professional.
What should I do if the cooktop trips the circuit breaker?
Hi Mason! First, make sure your electrical circuit can handle the cooktop’s power. Turn off the cooktop and disconnect all zones, check the cord and plug. If the breaker trips again when turning it on, it could be a short circuit or a control board issue — professional diagnostics are required.
