Cooking is a daily chore for many of us, and ovens make cooking easier and faster. If you have a Samsung oven, you know that you can always rely on the appliance’s standard and innovative features to get your cooking done. However, Samsung ovens can experience problems at times and fail to heat.
These are the most common reasons your Samsung oven will stop heating:
- Insufficient power supply.
- Oven ‘Demo’ mode is activated.
- The oven door is open.
- Oven gas pressure is too high.
- A weak oven igniter.
- The bake element is damaged.
We put together this troubleshooting guide with solutions for each problem to help you get back to your cooking as soon as possible should your Samsung oven stop heating. Some of the issues are simple and easy to fix, but others need more work and effort, and sometimes even the expertise of a professional. Let’s tackle them starting from the simple to the complex.
Insufficient Power Supply
Several power issues can affect your Samsung oven. Some will cause the oven not to turn on at all, but others will allow the appliance to turn on but not heat.
If you have a Samsung electric oven, your appliance should be plugged into a 240V wall outlet in order to switch on and heat up. If you plug your Samsung oven into a 120V outlet, the oven may turn on, but it will not have enough power to run the heating elements.
How To Fix Samsung Oven Insufficient Power Supply
Ensure your oven power cable is plugged into a 240V wall outlet. You can test the outlet for voltage by following these steps:
- Get a multimeter and set it to the AC function (voltage range).
- Wall outlets have ‘Hot’ (Left), ‘Neutral’ (Right), and ‘Ground’ (Lower/Upper) slots. Insert the black probe of the multimeter into the ‘Neutral’ slot first and the red probe into the ‘Hot’ slot next.
- Check the reading on the multimeter. It should show a value of around 240V. If instead, the value is more toward the 110/120 volts, the outlet has a lower voltage than your oven requires, which is why the appliance won’t heat up.
- Call in an electrician to install the correct wall outlet for your oven.

Caution! Testing a wall outlet for voltage is done with power flowing into the outlet. If you are not sure you can do the test safely, call a trained electrician to perform the test and fix any power outlet issues.
Oven “Demo” Mode Is Activated
Samsung oven Demo mode is used by appliance retailers for display purposes. When the oven is in this mode, the oven elements do not heat, but the gas cooktop will ignite. The control panel will also display tESt (tE5t), DEMO, or a ‘d’, depending on the model.
If your Samsung oven is new and you are using it for the first time, the appliance may have been left in Demo mode accidentally. You’ll need to deactivate this function to get your oven to start heating.
How To Deactivate Samsung Oven “Demo” Mode
The steps for deactivating the Samsung oven “Demo” mode vary from model to model.
For some models:
- Press the Timer icon on the control panel and hold it for 3 seconds.
- Tap the ‘Up’ or ‘Down’ arrow to set the value to zero.
- Hit the Start/Set button.
- Use the ‘Up’ and ‘Down’ arrows again to select OFF or ON.
- Tap the Start/Set button to save the changes.
For other models:
- Tap the Options button.
- Press the number ‘9’ pad.
- Press number ‘1’ to activate the OFF option.
- Hit the Start/Set button to save the changes.
You can check your model’s User Manual for the precise steps to take. If your User Manual does not have the instructions, contact Samsung through their Support Page. Ensure you have your model number.
The Oven Door Is Open
As a safety precaution, Samsung ovens are programmed to stop heating if you leave the door open for more than a minute. If you leave your oven door open accidentally by not closing it completely, the oven will not heat.
To fix the issue, check your door first to ensure it is well closed. If the door gasket is worn-out or broken such that it stops the door from closing properly, have the door repaired.
Oven Gas Pressure Is Too High
If you have a gas range and the oven will not heat when the cooktop is off, the gas pressure is too high.
It is advisable not to try troubleshooting oven gas issues. Samsung recommends contacting a professional installer or the gas company if you are using your range oven for the first time. Alternatively, you can visit Samsung Support and seek help from an agent.
A Weak Oven Igniter
This is a Samsung gas oven issue. Usually, the igniter on a Samsung gas oven takes 3 minutes (90 seconds) or more to ignite the burners. If the igniter is weak or not strong enough to get the flame to the burners, the safety gas valve will not open to allow the burners to light. Also, the igniter may just stay on with a low flame or go off entirely after some time.
So, while you’ll be thinking you’ve lit your oven, the oven will not be heating because the igniter has not lit the burners. A weak gas oven igniter needs to be replaced.
How To Replace a Weak Oven Igniter
First, observe the oven igniter and check if the flame is too low or the burners are not turning on after 3 or so minutes. If that’s the case, follow these steps to replace the igniter:
- Turn off gas and electricity to the range.
- Release the bottom panel inside the oven by removing the screws, then take it out of the oven.
- Unscrew the igniter from the mounting bracket on the burner.
- Press the tabs on the connector to remove the igniter plug from the harness.
- Fix the new igniter into the harness. Be careful not to touch the carbide electrode as this could cause it to fail before use.
- Screw back the igniter on the burner bracket.
- Place back the bottom panel and replace the screws.
- Turn on gas and electricity and test to see if the igniter lights the burners and the oven starts to heat.

The Bake Element Is Damaged
If you are using the bake function and the oven is not heating, the bake element might have burnt out. When functional, the bake element will glow red once it has heated up. If the element is not glowing, this could be a sign that it is damaged.
A burnt bake element may show other signs of damage like blisters or a broken part. You have to replace it to get the oven heating again.
How To Replace a Damaged Samsung Oven Bake Element
The procedure for replacing a Samsung oven bake element can vary depending on whether you are working with a wall oven or a free-standing range. The following steps for replacing a faulty bake element apply to Samsung free-standing ranges.
- Turn off the power to the oven and unplug.
- Pull the range away from the wall to make space for working.
- Remove the screws holding the back panel and set it aside.
- Locate the spade terminals of the element and unplug.
- Use a multimeter to test the element for resistance by placing each probe of the multimeter on one of the element terminals plugs. The multimeter will show a reading between 10 to 50 Ohms if the element is sound, otherwise, it is defective and needs to be replaced.
- Proceed to remove the bake element by first taking out the power cord from the block assembly. You need to first take off the screws before sliding out the cord.
- Remove the screws going into the terminal block and remove it.
- Remove the plate to which the terminal block was attached.
- Put the rest of the oven wiring to the side to access the insulation running across the assembly. Using a penknife, cut through the insulation. You will see the screws holding the bake element in place.
- Remove the two screws and carefully pull the element out. You may need to push down the insulation to pull out the element easily.
- Push in the new element where you’ve removed the old one and fix back the holding screws.
- Follow the reverse steps to put back all the parts.
- Power the range and test to see if the bake element resumes heating.
Note: This process may be as complex as it sounds. If you are not sure you can do it, call a trained Samsung oven technician to do the replacement. This video by ApplianceVideo.com can help make things a little easier:
If none of the above issues is causing your Samsung oven not to heat up, other less common causes could be to blame. These include a blown thermal fuse, a worn-out bake or broil spark electrode, or a faulty control board. Seek the service of a trained oven technician if your oven has complex issues.
