1. Check the power supply

Regardless of if you have a gas or electric oven, the best place to start is to check the power supply. To work properly, an electric oven requires 240 volts of alternating current, and a gas oven requires 120 volts of alternating current. If your oven isn’t getting this level of current, it might not heat or start at all.

To check if the power supply is correct, you need to:

1. Sometimes, the power socket can be faulty, which stops your oven from turning on. Before checking the socket to ensure it has the correct voltage, unplug your oven and try a different power socket. If your oven turns on when plugged into a different socket, the original socket will need to be repaired.
2. If the oven still doesn’t turn on when plugged into a different power socket, check that the socket has the right amount of voltage. If not, the power socket will need to be repaired or replaced. If you determine the socket has the right voltage level, move on to step 2.
3. After you repair the socket, check if your Samsung oven is working. If the oven still won’t heat, move on to step 2.

2. Check if the igniter is working

If you have a gas oven, you need to check if the igniter is working. If you have an electric oven, proceed to step 5. The igniter is the little component that ignites the gas so your oven can heat up. If the igniter stops working, your Samsung oven won’t heat.

To check the igniter, you need to: 

1. Locate the igniter and then try to turn your oven on.
2. If the igniter isn’t igniting the gas and lighting the flame, you will need to test it with a multimeter.
3. Testing the igniter requires removing it from your oven and then testing it with a multimeter. Before doing this, turn the gas and power off.
4. If the test shows no continuity, replace the igniter. If the igniter passes the test you can reinstall it and move on to step 3.
5. Once the new igniter has been installed, test if your Samsung oven is working. If it still doesn’t work, move on to step 3.

3. Check if the broil spark electrode is working

The next step is to check the spark electrode. This component helps to light up the bake or broil flame so your oven can heat. When it stops operating correctly, your oven can’t ignite and heat up.

To check the spark electrode:

1. Switch the power off to your oven and turn the gas off.
2. Locate the spark electrode and check if it is damaged. You can locate the electrode next to the burner.
3. If the spark electrode is damaged, it will need to be replaced. If it isn’t damaged, test it with a multimeter for continuity. To test the spark electrode, it will need to be removed from your oven.
4. If the electrode fails the test, replace it. If fine, reinstall the electrode and then move on to the next step.
5. Once you’ve installed the new spark electrode, attempt to turn your Samsung oven on. If it still doesn’t heat, move on to the next step.

4. Check if the safety valve is working

The next component to check is the safety valve. The point of the valve is to open up to provide the burner with gas. If the valve cannot open, your burner won’t get gas, and your oven will not be able to heat.

The easiest way to check the safety valve is to:

1. Make sure the gas and power are turned off.
2. Locate the safety valve and test it with your multimeter for continuity.
3. If the valve fails the test, replace it. If fine, move on to the next step.
4. Once you’ve installed the new valve, attempt to turn your Samsung oven on. If it still doesn’t heat, move on to the next step.

5. Check if the bake element is working

Electrical ovens get their heat from the bake element. When the element becomes faulty, your Samsung oven won’t be able to heat to the right temperature or not at all.

The best way to check the bake element is to:

1. Take the cover off the bake element (not all models have a cover).
2. Switch your oven to the highest heat setting.
3. After a few minutes, look at the heating element to see if it is glowing red. If not, this is a good sign it’s faulty.
4. Before replacing the heating element, test it with a multimeter for continuity.
5. If the element fails the test, replace it. If fine, move on to the next step.
6. Once the new element is installed, turn your Samsung oven on. If it still doesn’t work, move on to the next step.

6. Check if the thermal fuse is working

The next possible cause of your Samsung oven not heating is a faulty thermal fuse. The thermal fuse turns your oven off when it overheats. If the fuse stops working or doesn’t read the temperature correctly it can malfunction.

The best way to check the thermal fuse is to:

1. Turn the power and/or gas off.
2. Find the thermal fuse in your oven.
3. To test the thermal fuse, remove it from your oven, or disconnect it.
4. Use your multimeter to test the fuse.
5. If faulty, replace it. If fine, move on to the final step.
6. Once you have installed a new thermal fuse into your Samsung oven, check if the oven can now heat. If not, move on to the final step.

7. Install a new control board

The last step is to replace the control board in your Samsung oven. Sometimes, this will fix the problem, but you’ll only know for sure once it has been replaced. Before replacing the control board, consider getting a second opinion from a qualified technician.
