This guide will walk you through various reasons why a Samsung oven won’t heat up and show how to troubleshoot each issue. Remember, if you need professional help, J & B Appliance is always here for you.
Here’s Why Your Samsung Oven Won’t Heat Up Properly
Whether your Samsung oven is heating slowly, not reaching the right temperature, or won’t heat up at all, we have you covered! Start by troubleshooting these common oven problems before scheduling professional repair service.
1: Demo Mode Activated
One reason your Samsung oven won’t heat up could be that the demo mode is activated. This mode is designed for in-store displays and disables the oven’s heating functions. If your oven is stuck in demo mode, it won’t get hot, but you can quickly remedy the situation by deactivating the demo mode.
To turn off demo mode, simply follow these steps:
- Press and hold the “Energy Saver” and “Lighting” buttons simultaneously for 10-12 seconds.
- You should hear a chime and see the display turn off, indicating that the oven has exited demo mode.
2: Oven Door Not Closed All the Way
A Samsung oven not heating properly may be due to the oven door not being fully closed. If the door isn’t closed all the way, heat will escape, causing the oven to heat slowly or not at all. Before jumping to conclusions, inspect the door to ensure it’s closed and latched securely.
To fix this issue:
- Make sure the oven door is fully closed and latched.
- Check for obstructions that may prevent the door from closing, such as food particles or a damaged gasket.
- If the door still doesn’t close properly, consider seeking professional help.

3: Gas Igniter Failure (Gas Oven Models)
A gas igniter failure is another possible reason for a Samsung oven not heating. The igniter is responsible for lighting the gas and initiating the heating process. A malfunctioning igniter will prevent your oven from reaching the desired temperature.
To troubleshoot a bad igniter:
- Check if the igniter glows when the oven is turned on.
- If it doesn’t glow or glows weakly, the igniter may be faulty and require replacement.
- Contact a professional if you’re unsure about replacing the igniter yourself.
4: Defective Heating Element (Electric Oven Models)
If you’re wondering why your electric Samsung oven isn’t getting hot, a defective heating element could be the culprit. The bake element is responsible for heating the oven cavity, and if it’s not functioning correctly, your oven won’t heat up. Before attempting any repairs, ensure the oven is unplugged and cooled down.
To troubleshoot this issue:
- Turn off the oven and unplug it from the wall.
- Inspect the bake element for visible damage or signs of wear.
- Test the element for continuity using a multimeter.
- If damaged, replace the bake element or contact a professional for assistance.

5: Faulty Convection Fan
For oven models with convection cooking, a faulty convection fan can also cause a Samsung oven to heat slowly or not at all. The convection fan circulates hot air throughout the oven cavity for even cooking. An improperly functioning fan will impact the oven’s performance.
Here’s what to do:
- Turn on the oven and listen for the convection fan to start.
- Check for any visible damage, obstructions, or debris that might be preventing the fan from spinning freely. Clean any debris and remove
- With the oven off and unplugged, try spinning the convection fan blade with your hand. The fan should spin freely and smoothly. If it’s difficult to spin or seems to be catching on something, there might be an issue with the fan motor or the fan blade obstructions as needed.
- If the fan doesn’t start or makes unusual noises, it may need to be replaced. Seek professional assistance if you’re not comfortable replacing the fan yourself.
#6: Other Oven Part Failures
Lastly, other oven part failures, such as a faulty thermostat, oven sensor, or control board, can cause a Samsung oven not to heat up.
These components regulate the oven’s temperature and operation. Troubleshooting these issues can be more complicated, so it’s recommended to consult a professional appliance repair service like J & B Appliance.
To address these potential issues:
- Consult your oven’s user manual for guidance on troubleshooting specific components.
- If you’re not comfortable diagnosing or repairing these components yourself, contact a professional for assistance.
- Regular maintenance and cleaning can help prevent part failures and ensure your oven operates efficiently.
As you can see, there are numerous reasons why your Samsung oven won’t heat up properly. We hope this guide helps you identify and resolve the issue!
