Gas appliances are widely spread as electric ones but need specific knowledge and requirements. They are supposed to be dangerous and need constant maintenance and repair. When you face a problem with any gas appliance, the main advice is don’t try to repair it by yourself.

When you set your gas oven to preheat at 350 degrees Fahrenheit, place the cake on the oven counter. But after that, you turn the oven light on to see if the cake rises. And, to your regret, it is not. Opening the oven door, you realize the oven temperature has not increased above the temperature in the kitchen. Why won’t the oven heat up? To understand that, you should probably understand how a gas oven works.

Basic Reasons Why the Oven Stopped Working

Before paying attention to why the gas oven is not working but the stove is, let’s discover how it works. When selecting the bake or broil function in a gas oven, the control sends 120 volts of alternating current to the bake, broil igniter, or spark electrode. The igniter is wired to a safety valve, and as the component gets hot, it draws an increased current, or amps, through the valve. A bimetal arm inside the valve reacts to the heat generated by the amps, which causes the arm to flex and open, releasing gas into the oven’s bake or broil burner tube.

The igniter or spark electrode then ignites the gas into a flame to heat the oven. An igniter will remain on to keep the safety valve open until the oven reaches the designated temperature. A thermostat sensing bulb, or an oven sensor, monitors the temperature, and when the selected temperature is reached, the control will shut off the voltage to the igniter.

Remember that the temperature designated by the control is only an average one. The actual temperature will fluctuate throughout the cycle. Convection ovens will reduce this fluctuation by using a motorized fan to circulate the heated air evenly throughout the oven cavity with or without its own heating element.

Our gas technicians prepared a quick guide on what to check first to discover that the oven is not working:

  • Check gas supply
  • Bake or broil igniter
  • Gas Oven Safety Valve
  • PCB Circuit board
  • Touchpad or control panel

But below, we offer the main issues and troubleshooting when you face a problem with your gas oven.

Gas Oven Won’t Turn On But the Stovetop Works

In this part, our experts tried to give you simple step-by-step instructions, and we are sure that they will help you to find the cause of the problem and fix it so that you can get back to using your oven again. However, if at any time you feel like you are in over your head, turn the job over to a qualified third party. Why take the risk of burns or worse? You will need a few tools and replacement parts to take on the fix yourself. Either way, you’ll want to act fast because this problem will not get better, and it will cause a significant disruption in your daily life until you handle it.

  • Check the Power Outlet

    The first step is to ensure your oven is getting power to it. Even though your oven is gas-powered, it still requires electricity for the timer and other components to be able to operate. If the circuit breaker is okay, check that the power socket is working: you can try the oven in a separate power socket to check this out. If the power outlet or socket is faulty, it must be replaced by a qualified electrician only.

  • Check the Gas Supply

    Sometimes the gas supply can get impeded and not get through to your oven. Check that the main gas valve is turned on. If not, turn it back on. Check all of the other gas supply valves, such as those on the branch lines. If everything is working, move to another step.

  • Check Igniters

    This is the most common cause of an oven not working even while the stove does. Sometimes the igniter can wear out over time, or it can break for other reasons. If the igniter coil and the element for any signs of damage or discoloration, these are good signs that they may need to be replaced. If the igniter does work, the problem might be caused by another faulty component.

  • Check Burners

    If the gas igniter is working, the problem might be that the gas elements or burners are blocked. The easiest way to check them is to take them out and check that they aren’t blocked in any way. If they are, give them a clean and then put them back into the oven and see if this solves the problem. If not, move on to the next issue.

  • Thermocouple and Temperature Control Thermostat Issue

    The temperature control thermostat and thermocouple are the next components to check if you still haven’t found the cause of the problem. This component aims to monitor the temperature inside the oven and then cycle on the heat when the oven temperature gets too low. If the temperature control thermostat becomes defective, it can stop your oven from turning on. This doesn’t happen often, but if the igniter works, your best option might be to replace the temperature control thermostat and see if that solves the problem.

Any gas appliance is dangerous and can cause explosions if mishandled. Of course, we recommend not repairing it by yourself, and it is necessary to contact the pros and schedule a visit to check and repair your gas oven.

Hello Alex Salazar,
Sure, here are the steps of how to access the ignitor in the oven of a gas range:

  1. Make sure the power is turned off to the gas range.
  2. Open the oven door to gain access to the interior of the oven.
  3. Remove the oven racks to clear the way to the base plate.
  4. Locate the two screws holding the base cover in place; they are typically found at the rear of the oven plate.
  5. Unscrew and remove these two screws to release the base cover.
  6. Carefully pull out the oven plate to reveal the ignitor, which should now be accessible.

p.s. Gas igniter replacement in Ontario should only be conducted by a certified gas technician.

I have a gas oven relatively new with control board, bake stopped working, broil and stove top all works, also self clean stopped working. I replaced the igniter for the bake part but still the igniter doesn’t glow to fire the gas, any idea what should check next? Thanks

Hello Moe,
If you’ve replaced the igniter for the bake part of your gas oven and it still doesn’t glow to ignite the gas, there are a few other components you can check to troubleshoot the issue:

  1. Gas Safety Valve: The gas safety valve is responsible for allowing gas to flow to the igniter and the oven burner. If it’s faulty, it may not be opening to allow gas to flow. Make sure the gas supply to the oven is turned on and the valve is functioning correctly.
  2. Temperature Sensor: The temperature sensor in the oven helps regulate the temperature and can affect the ignition process. A faulty temperature sensor can prevent the oven from heating properly. Test the temperature sensor with a multimeter to ensure it’s working within the expected resistance range.
  3. Control Board: The control board is the “brain” of your oven, and it controls various functions, including the ignition of the bake element. Check the control board for any visible signs of damage or loose connections. If it’s damaged, you may need to replace it.
  4. Wiring and Connections: Inspect the wiring and connections between the control board, igniter, gas safety valve, and other relevant components. Loose or damaged wires can disrupt the ignition process.
  5. Thermostat: The thermostat is responsible for regulating the oven temperature. If it’s not functioning correctly, it may prevent the oven from reaching the desired temperature, including the temperature needed for the bake function.
  6. Oven Ignition Control Module: Some ovens have an ignition control module that regulates the ignition process. Check if your oven has one, and if so, ensure it’s functioning correctly.
  7. Door Lock Mechanism (for self-clean function): If the self-clean function is not working, the door lock mechanism may be malfunctioning. Make sure the oven door is properly locked during the self-cleaning cycle, and check the door lock assembly for any issues.
  8. Thermal Fuse: Some ovens have a thermal fuse that can blow if the oven overheats or if there’s an electrical problem. If the thermal fuse is blown, it may interrupt the power supply to the bake element and prevent it from igniting.
  9. Control Panel and Settings: Double-check the control panel and settings to make sure you have selected the correct baking mode and temperature. It’s possible that the oven is not heating because of incorrect settings.
  10. Contact Fix Appliances CA: Call us today at  888-242-0777. If you’ve checked all of these components and the issue persists, and you cannot resolve it on your own, schedule a service visit with our technician. Gas ovens repair can be potentially dangerous, so it’s essential to ensure safety while troubleshooting or repairing them.

Hello Luz
If your oven display shows “LOC” when you try to use the bake function, it means that the oven is in “Control Lock” or “Child Lock” mode. This mode is designed to prevent accidental or unauthorized use of the oven. You’ll need to deactivate the control lock feature to unlock your oven and use it again. Here’s how you can do it:

  1. Look for the control lock or child lock button on your oven’s control panel. This button may have a padlock icon or “LOC” displayed next to it.
  2. Press and hold the control lock button for a few seconds (usually around 3-5 seconds) until the “LOC” indicator on the display disappears.
  3. Once the control lock is deactivated, you should be able to set your desired oven temperature and start the baking cycle as usual.

If you cannot find a specific control lock button on your oven’s control panel or if the above steps do not work, consult your oven’s user manual for specific instructions on how to disable the control lock feature. If you no longer have the manual, you may be able to find a digital copy online by searching for your oven’s make and model.

If the problem persists and the “LOC” message continues to appear after trying to unlock the oven, there may be an issue with the control panel or electronic controls, and you may need to book a stove service repair with our Fix Appliances CA professional technician for further assistance and troubleshooting. Call us today at  888-242-0777.
