7 Causes Why the Samsung Electric Stove Burner Stays on High (Fixes Included)

The following factors could be the reasons why your Samsung electric stove burner stays on high:

Faulty Infinite SwitchInspect and replace the faulty infinite switch.
Damaged Element ReceptacleChange the element receptacle.
Faulty Control BoardHire a technician to fix the malfunctioning control board.
Defective Surface ElementTake the cooktop and swap the defective surface element with a new one.
Loose WireFind the loose wire and connect it properly.
Grounding ProblemConnect the ground wire to the stove’s chassis using a ground.
OverheatingEnsure proper operation of the cooling fan and the ventilation system.

1. Faulty Infinite Switch

Within the Samsung Electric stoves is a variable resistor known as the infinite switch. It regulates the voltage applied to the heating element. The burner becomes hotter as you turn the knob to a higher level.

The burner may stay on high even after you turn it down if the infinite switch is faulty. This occurs as a result of the malfunctioning infinite switch.

The Fix:

If the infinite switch is damaged, it is not able to provide the control board with the proper signal. Additionally, you might observe that the burner is sporadically turning on and off.

To check, open up the rear panel of your Samsung electric stove burner. Now, take the infinite switch out and test it with a multimeter. You will have to replace the infinite switch if it is malfunctioning. It is an easy procedure.

2. Damaged Element Receptacle

The element receptacle joins the Samsung electric stove burner’s heating element. The burner may stay on high if the element receptacle is damaged.

This occurs as a result of the heating element and the defective element receptacle not creating a strong electrical connection.

The Fix:

You must replace a malfunctioning element receptacle to fix it. First, make sure the stove’s electricity is off.

You must take out the surface element to replace the element receptacle. A few screws hold the element receptacle. It is situated beneath the surface element, in place.

You can easily unplug the element receptacle from the wiring harness. Now, you should remove the screws and replace it with a new one.

3. Faulty Control Board

The Samsung electric stove burner’s main controls are located on the control board. It is in charge of communicating with all other parts. The surface elements, infinite switches, and element receptacles are all connected with it.

The burner may continue to run on high if the control board is malfunctioning. This is because the control board sends incorrect signals to the other parts. Occasionally, the burner might not light up at all.

The Fix:

You will have to replace a malfunctioning control board. You will need expertise in electrical hardware for this repair. So, it is crucial to get a skilled appliance repair professional to complete it.

4. Defective Surface Element

Under the cooktop is the heating element known as the surface element. It has a ceramic insulator encircling it and is constructed of a metal coil. This metal coil may become defective.

The burner may remain on high if there is a problem with the surface element. This is due to the uneven heating of the problematic surface element.

The Fix:

A defective surface piece will require replacement to be fixed. Even if it’s a more complicated repair, you can still perform it yourself.

First, take the cooktop apart to replace the surface element. It’s easy to dismantle the surface element. Now, you should swap it out with a new one after removing the cooktop.

5. Loose Wire

If there is a loose wire, there is a possibility that the Samsung electric stove burner stays on high. This occurs as a result of the unsecured wire’s poor electrical connection.

This is one of the most common issues with older Samsung electric stove burners. The wires may become loose as you use the stove burner more often.

The Fix:

To address a loose wire in your Samsung electric stove burner, follow these steps:

  • At the breaker box, cut the stove’s electricity.
  • Now, take out the surface element.
  • You must find the loose cable.
  • Adjust the screw terminal holding the wire in position.
  • Now, you should replace the wire if it is damaged.
  • If it is loose, be sure to connect it tightly.
  • Finally, reattach the surface element.
  • Restore power to the stove and check if it works correctly.

6. Grounding Problem

For the stove to not cause electrical issues, it must be properly grounded. One of the many issues that might arise from an improperly grounded stove is the burner sticking on high.

The Fix:

You must ground the stove correctly to correct faulty grounding. Follow these actions:

  • Turn off the stove’s electricity from the breaker box.
  • Find the ground wire. Typically, the ground line is bare or green copper wire.
  • Verify the ground wire’s correct connection to the stove’s chassis.
  • If the ground wire is not attached correctly, you should attach it to the stove’s chassis.
  • Use a ground lug and a ground wire screw to attach it.
  • Now, turn the stove back on.

7. Overheating

Your Samsung electric stove burner might continue to run on high if it is overheating. The stove’s inability to adequately disperse heat is the reason behind this.

In such a case, the stove’s other burners may be malfunctioning. The stove’s automatic shut-off feature might also be noticeable to you.

The Fix:

Finding and addressing the overheating’s source is necessary to stop it from happening.

You will need to enhance the ventilation if the stove is not ventilated appropriately. You will have to replace the cooling fan if it’s not operating properly.
