Problem with the Gas Supply

If your Samsung gas oven isn’t getting enough gas, it won’t be able to heat up properly. You can check if this is the issue by checking if the stovetop is working – if nothing is lighting, there is likely an issue with the gas supply itself. 

To fix:

  • Make sure the gas shutoff valve is fully open. This will usually be located behind the range.
  • If the valve is open, the next step is to check for problems in the supply lines. Ensure the line is straight, and check for any kinks that might prevent gas from getting through. 
  • If there’s still no gas, contact your gas provider. There could be a larger gas supply issue that is to blame. 
  • Remember, gas is dangerous! Don’t attempt anything you are not comfortable with regarding your gas supply – it’s better to be safe than sorry. 

Problem with the Igniter

The igniter is what gives the spark to the gas supply and heats your oven. If there is a problem with your igniter, the oven won’t heat up, and it can even lead to gas leaking into your oven. 

To fix this:

  • Locate your oven igniter. It can usually be found near the burners in your oven, but you can check your Samsung user manual to find out exactly where it is. 
  • Make sure the gas supply is off, and test your igniter to see if you can see a spark.
  • If you can’t see a spark, try cleaning the igniter. Sometimes, it can get covered in grease and grime, which prevents it from sparking. 
  • If it’s still not sparking after being cleaned, it will need to be replaced. Order a replacement part from Samsung, making sure it matches the model of your oven. 
  • Remove the old, broken igniter by unscrewing it from its bracket and disconnecting it from any wiring. 
  • Put the new igniter in its place, and reassemble the oven.
  • Test to see if your oven is now igniting and heating up properly. If not, move on to the next step in our guide.

Dirty Burner

If your burner is blocked, it can mean that even though your gas supply is working fine, no gas can flow. This is pretty common in gas ovens because food debris, grease, and grime can obstruct the flow of gas. 

To check this:

  • Disconnect the oven from the power supply and turn off the gas.
  • Remove any trays necessary to get access to the burner.
  • Check to see if there is any obvious food buildup on the burner that may be blocking the holes and preventing it from lighting. 
  • If it looks dirty, remove the burner from the oven to clean it. 
  • Use a mild detergent and a stiff brush to thoroughly clean the grime from the burner. 
  • Make sure all the holes are unblocked – you might need to use a needle to ensure they’re clear. 
  • Put it somewhere warm and dry so that it can dry completely. Make sure it is absolutely dry before reinstalling.
  • Reattach the burner, turn the power and gas back on, and test to see if the oven is now lighting and heating up properly. 

Defective Safety Valve

The safety valve restricts gas flow to ensure the safe supply of gas to your oven, but sometimes it can malfunction and restrict the flow too much. This means your oven doesn’t heat up properly. It can’t be fixed if it’s faulty – it will need replacing. 

Here’s how to diagnose and fix the issue:

  • After turning off the gas and power to your oven, locate the safety valve. Your Samsung manual will show you where it is on your model.
  • Use a multimeter to test if the valve has continuity. If it doesn’t, it is faulty and will need to be replaced.
  • Order a replacement part.
  • Remove the faulty safety valve and install the new one, making sure you follow the instructions in your user manual. 
  • Turn on the oven and check to see if it’s heating properly. 

Faulty Thermostat

A faulty thermostat is a common cause of an oven not heating, whether a gas oven or an electric oven. This may be your issue if your oven is heating a little bit but never getting hot enough. 

To test this, you’ll need to use an oven thermometer to compare the actual temperature against the temperature the oven is set to. Place the thermometer in the oven, pick a specific temperature, then give the oven time to heat up. If there is a big discrepancy between the set temperature and what the thermometer shows, you have a thermostat issue and will need to replace it. 

To fix:

  • Order a replacement thermostat, making sure it matches your oven’s model.
  • After turning off the gas and power, locate the thermostat. They’re usually behind the control panel. 
  • Disconnect the old thermostat from the wiring harness, making sure to take note of how it’s connected. 
  • Put the new thermostat in its place, then reassemble the control panel.
  • Turn the gas and power back on and test to see if your Samsung Oven is now heating up correctly.
