If your Samsung electric stove or cooktop won’t turn off, follow these steps to ensure safety:

  • Disable the Breaker: Urgently locate and switch off the breaker supplying power to the appliance in your home’s electrical panel.
  • Locate the Electrical Panel: Typically found in a basement, utility room, or garage, the electrical panel houses circuit breakers.
  • Identify the Correct Breaker: Look for labels indicating the stove or cooktop’s breaker. If no labels exist, find a switch positioned differently or with a higher amperage rating.
  • Switch Off the Breaker: Firmly move the breaker from “on” to “off” using pliers or protective gloves for safety.
  • Prioritize Safety: Always prioritize safety when handling electrical appliances.
  • Prevent Further Attempts: Disabling the breaker prevents the appliance from attempting to power on further, buying time for investigation and solutions.

1. Jammed Control Knob

If your Samsung electric stove or cooktop won’t turn off, a jammed control knob might be to blame. Here’s what you can do:

  • Safety First: Disconnect the appliance from the power supply by unplugging it or turning off the breaker.
  • Inspect the Knob: Check for debris or damage on the control knob’s surface.
  • Clean the Knob: Use a soft cloth with mild soapy water to gently clean any buildup or residue.
  • Apply Heat: Use a hairdryer on low heat to warm the knob, which can help loosen sticky substances.
  • Lubricate: Apply silicone spray or WD-40 to the knob for smoother movement.
  • Contact Professional Help: If DIY methods don’t work, contact a certified technician for long-term solutions and wiring issues.

Regular maintenance and prompt problem-solving ensure smooth operation and extend the lifespan of your Samsung electric stove.

2. Defective Infinite Switch

If your Samsung electric stove or cooktop won’t turn off, a faulty infinite switch could be to blame. Here’s what you can do:

  • Check for symptoms like a burner staying on at high heat regardless of knob position.
  • Visually inspect the infinite switch for physical damage or loose connections.
  • Use a multimeter to test continuity and resistance in the switch.
  • If the switch is defective, replace it following safety precautions and guidelines.

3. Wiring Anomalies

Wiring issues can cause a Samsung electric stove or cooktop to remain on when it should be off. Here’s what to consider:

  • Loose or damaged wire connections can disrupt electrical flow, preventing the stove from receiving the signal to shut down.
  • Vibrations and movements over time can cause wires to become loose or frayed, hindering the cooktop’s ability to power off.
  • Inspect wiring connections carefully and securely reconnect or replace any loose or damaged wires found.


  • Incorrect wiring configurations during installation or repairs can lead to irregular electrical signals, preventing proper shutdown.
  • Professional technicians specializing in Samsung appliance repair can accurately identify and rectify wiring issues while ensuring safety measures are followed.

Promptly addressing these wiring anomalies can help resolve issues with your malfunctioning Samsung electric stove or cooktop not turning off properly. Always prioritize safety and seek professional assistance when needed.

4. Faulty Thermostat

When your Samsung electric stove or cooktop won’t power down, a faulty thermostat might be to blame. Here’s what you need to know:

Possible Cause: Faulty Thermostat

  • The thermostat regulates the appliance’s temperature, but when it malfunctions, the stove or cooktop may stay on.
  • A common cause is a worn-out or damaged sensor, leading to inaccurate temperature readings.

DIY Troubleshooting Steps

  • Safety first: Unplug the stove or turn off its circuit breaker.
  • Consult your repair guide and locate the thermostat.
  • Check for loose or damaged wiring connections and repair if comfortable doing so.
  • If wiring looks fine, test and repair or replace specific components like sensors or switches as per manufacturer instructions.

5. Damaged Selector Switch

A damaged selector switch can cause issues with your Samsung electric stove or cooktop, such as refusing to turn off. Here’s what to do:

  • Check for symptoms like inability to change cooking zones or adjust temperature settings.
  • Perform a visual inspection for physical damage like cracks or loose connections.
  • Ensure safety by disconnecting power before attempting any repairs.
  • Clean connection points between wires and terminals using an electrical contact cleaner spray and a soft brush.
  • If DIY solutions don’t work, seek professional assistance from an authorized service technician for Samsung appliances.

Remember, prioritize safety and seek professional help if needed to avoid further damage or personal injury.

6. Malfunctioning Control Board

If your Samsung electric stove or cooktop won’t power off, a faulty control board could be the culprit. Here’s what you need to know:

  • Control Board Functionality: The control board regulates various functions like temperature control and cooking time.
  • Common Causes of Malfunction: Electrical surges or wear and tear can damage the control board’s circuitry or connections.

Troubleshooting Steps

  • Disconnect power to the appliance and consult the user manual.
  • Inspect the control board for visible damage using appropriate tools.
  • Attempt DIY repairs cautiously, focusing on replacing damaged parts or securing loose connections.

7. Electrical Supply Issues

Electrical supply issues can cause a Samsung electric stove or cooktop to fail to turn off, posing safety risks. Here’s what to do:

  • Address Wiring Anomalies: Improper or fluctuating voltage supply due to wiring issues can disrupt the appliance’s operation. Engage a qualified electrician to diagnose and fix wiring problems like faulty connections or damaged cables.
  • Inspect Electrical Connections: Regularly check and secure electrical connections to prevent issues. Ensure they are free from corrosion and securely attached.
  • Check Thermostat Functionality: A malfunctioning thermostat can lead to continuous heating, preventing the stove from shutting off. Refer to your Samsung appliance repair guide for instructions on replacing a faulty thermostat, or seek professional assistance if needed.

By promptly addressing wiring anomalies and ensuring proper thermostat functionality, users can effectively resolve power-down issues with their Samsung cooktops, enhancing safety and performance.
