6 Reasons Why the Samsung Gas Oven is Not Heating

You've come home after a long, tiresome day, and your belly grows in hunger. As you go, preheat the oven, only to find out the oven is not heating up. Before it drives you up, wait a moment and take a deep breath. 

We have curated an easy-to-follow guide that will help you troubleshoot the issue right away if things are simple. For a little complex problem, you can still flex your DIY muscles to resolve the issue.

Faulty or Damaged Igniter

An igniter is essential for a gas oven to heat up and provide the spark for gas to ignite. This ignition process also allows the oven burner to turn on and the gas valve to open. 

But with time and use, the igniter can wear and get weakened, reducing its efficiency and effectiveness. As a result, the igniter takes longer to reach the temperature to ignite the gas, delaying the preheating process. At times, the igniter falls short of reaching the required temperature to ignite the oven, leading to a faint whiff of gas. 

However, the Samsung oven has safety features that automatically shut off the gas valve and stop the gas supply if the igniter doesn’t get hot enough. When the igniter is damaged, the oven won’t heat up. In either case, you need to replace the igniter. But how do you know whether the igniter is damaged or not? Well, it is quite simple.

First, you must open the oven by removing the oven racks and metal plates. When you locate the igniter and gas burner, turn on the oven, and the igniter should glow within a few seconds. If it is not glowing, the igniter may have an issue that needs replacing.

Sometimes, the igniter would glow without igniting the gas. This could be due to a malfunction in the gas valve or its associated components. You can also visually look for cracks, damage, or discoloration. If anything is visible, there is a high chance that your Samsung oven igniter requires replacement. 

Demo Mode is On

In the demo mode, the Samsung oven doesn’t heat. Demo mode allows the users to explore the controls and settings of the appliance without the potential risk of activation or heating up. In the retail showroom, you can find Samsung ovens set in demo mode, enabling prospective buyers to test out the appliance’s wide range of features.

If your Samsung oven is knowingly or unknowingly in demo mode, it won’t heat up. For your help, the Samsung oven usually displays a code or icon in demo mode. This code is model-specific and differs from one Samsung oven model to another. 

Check the owner’s manual to determine the specific icon displayed when your Samsung oven is in demo mode. The common icons or codes in the Samsung oven displayed in the demo state are “tESt,” “d,” and “DEMO.” Once you find one of these icons on the oven’s control panel, you have to exit or turn off the demo mode for normal operation.

If you cannot exit the demo mode, the owner manual will also instruct the method. Instructions for turning off the demo mode vary based on the specific Samsung model. 

Sometimes the oven is not heating for obvious cause– the appliance is not plugged in. Before doing anything else, check out the power source of your appliance and make sure the appliance is properly plugged into the outlet. 

When you are sure that the appliance is plugged in just fine, check the circuit breaker box to see if the circuit breaker of the Samsung oven is in a tripped state. Look for any breakers that are in the “tripped” position. A tripped breaker will be in a position right in the middle, just between the “on” and “off” positions, or maybe slightly pushed to one side.

If the circuit breaker of your gas oven is tripped, switch the breaker to “off” and wait for 30 seconds. After that, set the breaker back to the “on” position. It will reset the circuit breaker, and you may hear a clicking sound. 

Remember that the Samsung eclectic oven requires 240V connections, and a gas oven needs 120V connections. Ensure that your kitchen outlet can supply the required voltage. However, the Samsung oven can still operate at a lower voltage than the required one. Under these circumstances, the appliances may take longer time to preheat, and you may need to wait longer for cooking and baking. 

Check the Gas Supply

After inspecting the power supply, you should verify whether the gas supply is turned on. There are straightforward and more nuanced methods to perform this check. If your gas oven fails to ignite, proceed to confirm whether the cooktop burner is lighting. 

If neither the cooktop burners nor the gas oven ignites, the issue is likely related to the gas supply. In such cases, it’s advisable to promptly contact the gas service provider responsible for supplying gas to your residence.

In certain instances, the gas oven may heat up when the cooktop burner is lit, but it doesn’t heat up when the burner is turned off. This indicates a potential issue within the gas supply system. Most probably, the gas pressure for your Samsung ovens may be too high. You need to call a pro or the gas supplier to fix it. 

Make Sure the Door is Closed

Most modern Samsung ovens have a door sensor that can detect if the oven door is open. If the oven door remains open for more than one minute, the oven will turn off automatically. This is more of a safety feature of Samsung ovens. The door sensor prevents the oven from running with the door open, which could be hazardous and a waste of energy.

Damaged Bake Coil 

The bake coil or element radiates moderate heat into the chamber where foods are being cooked. If the bake coil has cracks, damage, or burns, it can cause areas of the coil to not heat up properly. Replacing is the only solution if the bake coil is not functional. 

One simple way to check for issues is to ensure the bake coil glows bright orange when fully heated. If it doesn’t, it indicates that the coil may be burnt out or damaged. This results in uneven, inadequate heat in the oven and food not baking properly. Also, the oven may take much longer to preheat or not reach the predefined temperature. 

In severe cases, a fully broken bake coil will cause the oven not to heat at all. You will see no glow in it, meaning zero heating capability. Replacing the bake element is typically required to properly fix an oven that is not heating due to a bad element. Plus, it’s not usually repairable.


In most cases, the causes and solutions we’ve discussed earlier effectively resolve the frustration of a non-heating oven. Sometimes, you must replace parts like the igniter or bake coil. 

If you have the necessary skills to conduct a basic-level diagnosis of appliances, you can replace those parts with the right knowledge. Otherwise, you can allocate the job to a professional, incurring some associated costs. You can also reach out to the Samsung Support Center to initiate a service request.
