Why is my Samsung oven not heating up?
A Samsung oven may fail to heat up because of an insufficient power supply, left-open doors, or the oven being set to Demo Mode.
Furthermore, defects in the oven’s broil element, thermostat, thermal fuse, bake element, and thermal igniter can be causes for the heating problem as well.
How do I fix my Samsung oven’s heating problems?
Checking the Samsung oven’s power supply, doors, and mode settings should be the first thing to do if you feel the appliance has heating problems. It is wise to troubleshoot these first before any of the other components of the oven.
However, if you do find that everything seems normal but the oven is still having trouble heating, then you should now troubleshoot the components of the oven – the broil spark, thermostat, thermal fuse, oven bake element, and oven igniter.
We will be listing each problem and its corresponding solutions in the table below:
| Causes | Solution |
| Insufficient Power Supply | • Check if your Samsung oven has an ample power supply. • For gas-powered models, make sure that the oven still has gas in its reserves. It’s also vital to check if the gas pressure is sufficient enough to provide the oven with power. • On the other hand, electric ovens need to meet their required voltage of 240V to function. So double-check if your oven is plugged into an outlet with the proper voltage beforehand. |
| Opened Oven Doors | • Make sure the oven doors are closed and secured while using the oven for heating or cooking. |
| Activated Demo Mode | • Disabling Demo Mode to make the oven operate normally varies depending on the model. • It is recommended to refer to the user manual of your Samsung oven for the button inputs to disable Demo Mode. |
| Broken Broil Element | • If you find the broil element inside your oven to be broken, replace it with a new one. • The broil element is located on the ceiling inside the oven but you may need to disconnect some wiring and electronics in the back compartment to completely access it. • Some of the steps in replacing the broil element may be tedious, so make sure to have professional help on standby when you attempt to replace the component. |
| Uncalibrated and/or Defective Thermostat | • Run a multimeter test to determine if the thermostat needs replacement or a simple calibration. The thermostat is located inside the compartment under the cooktop. • The thermostat should test negative for continuity under room temperature to pass the test. Otherwise, testing positive means the thermostat is defective. • A simple calibration is needed if the thermostat passes the continuity test. • Calibrating the thermostat requires a Philipps screwdriver and an oven-safe thermometer. Preheat the oven until the reading on the thermometer reaches 350° F, and then calibrate the thermostat to the same temperature. • On the other hand, if the thermostat fails the continuity test, it needs to be replaced. • Don’t hesitate to call for professional help if you have trouble with any of the steps while working on the thermostat. |
| Faulty Thermal Fuse | • Replace the thermal fuse with a new one. The fuse is usually situated inside a compartment under the oven’s cooktop. • Open up the cooktop and disconnect the thermal fuse from the other electronics. Connect the oven’s wiring to the new thermal fuse and properly close up the oven to finish the repairs. • The task to replace the thermal fuse may sound simple but it could prove to be daunting. Call for professional help if the process is too difficult. |
| Defective Oven Bake Element | • Replace the Samsung oven’s bake element with a new one. It is usually located in the back compartment of the oven. • Call for professional help if the process to replace the bake element is difficult for you. |
| Failed Oven Igniters | • Access and replace the oven igniters of your oven. It is usually inside a compartment under the appliance. • This may be a difficult and dangerous task, so don’t hesitate to call for professional help once you feel overwhelmed with any of the steps or instructions. |
| Quick Note: • Most of a Samsung oven’s components, such as the broil spark, can be difficult to access and repair. You may still attempt to do the maintenance on your own but be prepared to call for professional help if you find any of the steps to be difficult. • Furthermore, if you need to replace any of the Samsung oven’s components, you can easily identify the correct one by referring to your appliance’s serial number. This helps avoid any parts from mismatching and will save you precious resources as well. |
Insufficient Power Supply
An insufficient power supply will prevent your Samsung oven from functioning and heating at all. The appliance needs a sufficient amount of gas or electricity from its power supply to work properly.
Solution: Inspect your oven’s power source and perform the necessary steps to restore an ample power supply to the oven.
For gas-powered oven models, there may be a lack of gas pressure or no gas at all, which may be the cause of the lack of power. Make sure that the valve on your gas supply is on when using the oven, and check if there is gas inside at all.
Meanwhile, electric oven models are incapable of heating if they lack sufficient voltage. Remember to plug the oven into its prescribed socket – the usual voltage for most ovens is 240V to function, but refer to your user manual if necessary.
Opened Oven Doors
Samsung ovens cannot begin to heat up when their doors are open. They come with a safety feature that prevents their heating function whenever open doors are detected by the appliance.
This is to ensure any accidents do not happen, as well as to maintain proper safety in the kitchen at all times. The oven’s control panel should also be able to display if the oven doors are closed and locked while in use.
Solution: Gently close the oven doors whenever you plan to use the oven for heating or cooking. Make sure that they are shut tight and that the oven’s control panel shows that the doors are locked.
Activated Demo Mode
Demo Mode in a Samsung oven will mainly disable the appliance’s heating function. This is because the mode is used whenever the appliance is displayed in stores, showrooms, and conventions.
Most Samsung ovens will display tESt (or tE 5t) on the control panel if Demo Mode is currently active. There are some models that would show a d or a D, although wall ovens will show DEMO on their control panel display instead.
Solution: Disable Demo Mode for the oven to operate normally. The button input may vary depending on the oven’s model number, so it’s recommended to refer to your user manual for the button inputs to disable Demo Mode.
Broken Broil Element
The broil element of your Samsung oven enables the broil function of the appliance. This function is designed to crisp or add browning to already-cooked food as the source of heat only comes from the oven’s ceiling.
A broken broil element can usually be diagnosed if the oven does not heat up consistently or at all. It will also give off unwanted sparks when in use and may cause harsh odors to come from the inside of your oven.
Solution: Replace the broken broil element with a new one to fix the heating issue of your Samsung oven.
- Step 1: Power off and disconnect the Samsung oven from its power source.
- Step 2: Remove the back panel of the oven with a screwdriver set and carefully lift it up and set it aside.
- Step 3: The temperature sensor’s wiring is located in a slot somewhere on the top of the back compartment. This small slot has a form of insulation material inside it and should have the sensor’s wiring and electronics connected to it.
- Step 4: Now, we need to turn our attention to the front of your oven. Remove the oven door by using a flathead screwdriver to pull down the locking tabs of the door and carefully set it aside.
- Step 5: Remove all of the oven racks and accessories inside the oven and set them aside.
- Step 6: Inside the oven, retrieve the temperature sensor by using a Philipps screwdriver to remove the screws keeping it in place.
- Step 7: Remove the screws keeping the broil element secured with a Philipps screwdriver. There should be screws on the ceiling and on the back of the oven’s interior.
- Step 8: Gently retrieve the old broil element and replace it with a new one. Carefully repeat the steps in reverse to successfully install the new broil element and return your oven back to normal condition.
Remember, if you have any sort of difficulty performing any of the given instructions above, feel free to call a professional to do the troubleshooting and repairs for you instead.
Uncalibrated and/or Defective Thermostat
The Samsung oven’s thermostat is a vital component for managing the temperature of the appliance. An uncalibrated thermostat can cause issues such as inaccurate temperatures that can lead to lower or higher temperatures being used in the oven.
A defective thermostat can cause the fans of your oven to turn on and continuously operate – leading to unnecessary cooling when trying to raise its temperature for cooking or other purposes.
Solution: Perform a continuity test on the thermostat to verify if it is only uncalibrated or is already defective and would need replacement.
- Step 1: Make sure that the oven is not turned on and is cut off from its power source.
- Step 2: With a Philipps screwdriver, remove the stove top cover to access the compartment beneath it – where the thermostat is located.
- Step 3: Disconnect the thermostat from the wiring and electronics of the oven to retrieve it.
- Step 4: Perform a continuity test on the thermostat using a multimeter.
A negative reading under room temperature means the thermostat passed the test and may only need calibration.
Meanwhile, a positive reading under room temperature signifies that the thermostat failed the test, is deemed defective, and is due for replacement.
- Step 5: Calibrate the thermostat if it passed the continuity test. Otherwise, replace it with a new one.
Here are the steps to calibrate the thermostat in both types of controls:
- Step 1: Place an oven rack inside the oven and then place an oven-safe thermometer in the center of the rack.
- Step 2: Heat the oven to 350° F while keeping the thermometer inside the oven. Make sure that the doors of the oven are closed during this step to have accurate temperature readings while the appliance is heating.
- Step 3: Once the oven has finished preheating to 350° F, check the temperature on the thermometer by looking through the door. The thermostat needs calibration if the thermometer reads a difference of 15° F from the set 350° F.
- Step 4: Calibrate the oven’s thermostat accordingly.
- For Digital Controls:
Check the user manual to identify the button inputs to calibrate the temperature. Most ovens use the control panel’s arrow keys or menu prompts to adjust the thermostat.
- For Analog Controls:
Remove the oven temperature knob and turn it over. It should have one or two screws on the back to adjust the display – turn the screws counterclockwise if the oven is running cold and clockwise if otherwise.
- Step 5: Save the new calibrated settings. The oven should now be heating correctly according to the displayed temperatures on the oven’s thermostat.
Retest the oven’s temperature and repeat the calibration process if you find it necessary to do so.
Here are the instructions to replace the thermostat if found to be faulty:
- Step 1: Acquire a new thermostat to replace the old one.
- Step 2: Connect the new thermostat to the oven’s wiring and electronics.
- Step 3: Return the stove top cover and make sure it is secured back into place to close up the oven.
- Step 4: Connect the oven back to its power source once you are done with the troubleshooting and repairs.
Remember to never hesitate to call in a professional if you find any of these steps and instructions to be difficult to do on your own – that way, you’ll be saving yourself time and effort.
Faulty Thermal Fuse
The thermal fuse inside the Samsung oven is responsible for preventing any instances of overheating. A faulty one may prevent the appliance from heating up and/or cause the oven to have irregular temperatures when in use.
Solution: Perform a continuity test on the thermal fuse to verify if it is causing the heating issues of the oven. Replace the thermal fuse if it does not pass the continuity test.
Here are the instructions to perform the continuity test on the thermal fuse and how to replace it if found to be faulty:
- Step 1: Power off and disconnect your Samsung oven from its power supply to safely access the compartments of the appliance.
- Step 2: The thermal fuse is typically located under the stove top cover or the oven’s back compartment. Refer to your user manual to verify where the fuse is in your oven before removing any of the covers.
- Step 3: Once you know the location, open up the cover and access the thermal fuse. Most Samsung oven thermal fuses look like the picture provided below:
- Step 4: Disconnect the thermal fuse from the oven’s wiring and electronics. Use a screwdriver to remove it from its place.
- Step 5: Use a multimeter to perform a continuity test on the thermal fuse. Touch one of the multimeter’s probes on one end and the other probe on the opposite end.
If the multimeter’s needle moves and/or reads 0 ohms of resistance, then the thermal fuse has continuity and should still work properly.
On the other hand, if the multimeter’s needle does not move and/or does not have any significant change in its reading, then the thermal fuse has no continuity and has likely blown its fuse.
Here are the instructions to replace the thermal fuse if found to be faulty:
- Step 1: Acquire a new thermal fuse to replace the old one.
- Step 2: Screw the new thermal fuse into place and reconnect its wiring and electronics.
- Step 3: Cover up the compartment you accessed and make sure that it is closed tightly.
- Step 4: Be sure to reconnect your oven to its power source after all the troubleshooting and repairs.
Feel free to call a professional to help you perform the troubleshooting and replacement of the thermal fuse if you find any difficulty doing it by yourself.
Defective Oven Bake Element
The bake element of your Samsung oven is needed for the appliance to enable higher temperatures throughout the entire oven.
As mentioned earlier in this article, the broil element is used for crisping or browning already-cooked food. Meanwhile, the bake element is used for cooking food thoroughly, usually activating the heating elements on all sides of the oven.
You can identify if your Samsung oven’s bake element is defective if:
- The appliance has inconsistent temperatures when heating.
- It takes more time than usual to preheat the oven.
- The oven is unable to heat up at all.
Solution: Access and replace the Samsung oven’s defective bake element with a new one.
- Step 1: Power off and disconnect the Samsung oven from its power source.
- Step 2: Access the back compartment of the oven. Start with removing the back panel with a screwdriver set and then carefully set it aside.
- Step 3: The bake element is located in a slot at the bottom of the back compartment. This small room is blocked off by a couple of wires and electronics, so start disconnecting any electronics in the way.
- Step 4: There should also be some more panels in the way of the bake element’s compartment. Remove these using a screwdriver set to have full access to the bake element.
- Step 5: Take off the screws securing the bake element in place. There should be screws on each side of the component holding it in place.
Once the screws are removed, you can carefully retrieve the old bake element.
- Step 6: Gently slide the new bake element inside its compartment and make sure to secure it by putting all of the screws back into place.
- Step 7: Attach all the other panels that were removed earlier and reconnect all the wiring and electronics of the oven.
- Step 8: Finish up by closing up the back compartment with the back panel you removed earlier, and remember to properly connect the oven to its power source after finishing up the repairs.
If you have any difficulty following the steps in replacing the bake element, then feel free to call for professional help to assist you with the troubleshooting and repairs of the appliance.
Failed Oven Igniters
The oven igniters of a Samsung oven allow heat to build up inside the oven. Gas-powered ovens light gas with their igniters to produce heat, while electric ovens use their igniters to concentrate electricity to produce high temperatures.
The oven cannot heat up if any of its igniters fail since it becomes impossible to create heat for the appliance. Most of the oven’s functions cannot be used in this situation until the failed igniters are replaced.
Solution: Replace the failed oven igniters with new ones to restore the oven back to functioning capability.
Here are the instructions to access and replace the oven igniters:
- Step 1: Power off the Samsung oven to safely access the bottom compartment.
- Step 2: Take out the bottom sliding door by freeing its hooks from each side of its sliding rail mechanism. This should now give you free access to the bottom compartment.
- Step 3: There should be a panel on the floor of the oven. Remove the screws and gently push the panel forward and then pull it out to expose the bottom compartment underneath it.
- Step 4: There should be another panel covering the parts inside the bottom compartment. Take it out by removing its screws and then set it aside.
- Step 5: You should now be able to see the oven igniters – the one located at the top of the oven is the broil igniter, while the one on the bottom is the baking igniter. Test them by heating the oven and observing the igniters.
If the igniters turn into a red-hot color, then they are working as intended.
On the other hand, if they do not react to the oven being set to heat at all, then they need to be replaced.
- Step 6: After letting the oven cool down from the heating test (give it 30 minutes to be safe), replace any failed igniters with new ones. Start by removing the cables connected to either the broil igniter and/or the baking igniter.
- Step 7: Remove the screws securing the pipes (which are holding the igniters) and carefully take them out of the oven.
- Step 8: The igniters should have screws attaching them to their respective pipe, so simply remove the screws. This should free the igniters from their place.
- Step 9: Attach the pipe back into its place and reconnect the cables of the igniters to the oven.
- Step 10: Test out the new igniters by heating the oven and observing if they are working as intended.
- Step 11: Let the oven cool again (for approximately 30 minutes) before proceeding. Next, cover up the bottom compartment with both of the panels that you had to take out earlier.
- Step 12: Finish up the repairs by reinstalling the oven’s bottom sliding door.
If you have any sort of trouble following the instructions provided, always remember that you can call a professional to help you perform any of the troubleshooting needed for your Samsung oven.
You should now be equipped with enough knowledge to troubleshoot and fix the heating issues of your Samsung oven, and any future problems will be a piece of cake for you to solve.
