Has your electric cooktop suddenly stopped working? This is a real problem for any modern kitchen. The causes of the malfunction can be simple issues, such as power supply interruptions, or more complex ones, like a control board failure. Often, all problems related to a cooktop breakdown require thorough diagnostics and proper repair. Learn more about our cooktop, range stove and oven repair services:

Reasons Why the Electric Cooktop Is Not Working
Power Supply Issues
Power supply problems or interruptions are one of the most common reasons why the cooktop does not turn on. In some cases, the circuit breaker in the panel trips. This happens due to an overload in the network. A damaged power cord and/or an outlet with an unstable connection can also cause this problem. Even if the power surges are brief, the cooktop can still stop working. In houses with old wiring, such problems are more common.
Solution
- Check the power connection
- Check the circuit breaker position
- Try plugging the cooktop into another outlet
Pro Tip:
Recommendation before looking for other causes of the malfunction: Check the voltage in the outlet and make sure there is power using a multimeter.
Burnt-Out Heating Elements
Heating elements are located under the surface of each burner. A burnt-out heating element can be the cause of such problems: the burners heat unevenly, do not heat up, or even stop working completely. During use, especially with prolonged or too frequent intensive use, the elements can become deformed, crack, or burn out. In most cases, the problem develops gradually. At first, you may notice that the burners begin to heat up more slowly than usual, and gradually they start working inconsistently. Visually, this is expressed in scorch marks, cracks, or a changed color.
Solution
- Inspect each burner and its heating element.
- If you find damage, or have noticed unstable operation over a certain period, the heating elements need to be replaced with new ones.
- Make sure the new parts are compatible with your cooktop model, otherwise the replacement will be meaningless and the heating elements will work inconsistently.
Faulty Infinite Switch or Control Knob
The function of regulating the burner heating lies with the power switch, or the so-called infinite switch. If it is not working properly, the cooktop may heat at only one temperature level or not respond to temperature changes. Sometimes the burner may stop working a few seconds after being turned on or heat unevenly. Over time, the contacts inside the switch wear out, which causes malfunctions. Special tools are needed for diagnostics, because such a fault is not always visible.
Solution
- You need to check the switch for circuit continuity using a multimeter.
- If the test shows no contact, replace the element with a new one.
- Before replacement, be sure to make sure that the new element is compatible with your cooktop model.
Malfunctioning Internal Wiring or Connections
The reason why the cooktop stopped working may not be visible externally. In this case, the cause may be that the internal wires and connections are damaged or oxidized, the contacts may be weakened, and the insulation may be cracked. Often with such malfunctions, you may notice that the cooktop started heating inconsistently or even shutting off in the middle of operation.
Solution
Remember that repairing internal wiring on your own is very dangerous. This can lead to electric shock. In this case, if you do not have specialized knowledge, many years of experience, and the necessary tools, we recommend contacting a qualified specialist to check the internal connections and repair the wiring.
Broken Thermal Fuse or Safety Sensor
Many modern electric cooktops are equipped with thermal fuses and sensors that prevent overheating. If such components fail, the cooktop may completely stop working. The problem appears suddenly: after turning it on, the cooktop does not respond, even if the power supply is fine and the elements are working. In such cases, you cannot simply replace the component without checking the entire circuit, otherwise the malfunction will occur again.
Solution
Replace the burned-out thermal fuse or sensor with a new one suitable for your model. Make sure the part is original or certified so that it properly performs its safety function.
Problems with the Control Board
Modern cooktops are often controlled by an electronic board. If the board fails, the burners may work inconsistently, the touch buttons may stop responding, and the display may show error codes. Such malfunctions most often occur due to power surges, liquid spills, or physical damage. It is almost impossible to diagnose board failure on your own without special knowledge.
Solution
You need to contact a specialist to test the board and replace it if necessary. Using an original board ensures the proper operation of all cooktop functions.
Pro Tip:
To extend the lifespan of the board, use a voltage stabilizer for the entire kitchen. This will protect the cooktop from power fluctuations and prolong its service life.
Repair Cost

What are the signs that the control board is about to fail?
Hi James! Some common warning signs include unresponsive touch buttons, burners turning on or off by themselves, error codes on the display, or inconsistent heating across multiple burners. Flickering lights or a completely blank display can also indicate a failing board. If you notice these issues, it’s best to have the board checked before it stops working completely.
How long does it usually take to diagnose an electric cooktop?
Hi Michael! On average, our professional technicians can complete a full diagnosis within 30–60 minutes. The exact time depends on the complexity of the problem—for example, checking wiring connections and switches may take less time, while testing the control board or sensors may take longer.
How often should preventive maintenance be performed on an electric cooktop?
Hi Robert! For most households, a yearly inspection and cleaning are recommended. Regular maintenance helps spot early signs of wear, prevents electrical issues, and keeps the cooktop running efficiently. If you use your cooktop heavily or live in an area with frequent power surges, scheduling maintenance every 6–9 months may be a better option.
