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? If you find that the fan in your refrigerator has suddenly stopped working, it’s crucial to examine the electrical connections and wiring of the fan motor for any possible problems. Additionally, inspect the fan’s wiring closely for any signs of damage or looseness. If everything appears to be in order, consulting a detailed list of common issues can aid in troubleshooting effectively, thus ensuring your refrigerator functions without any hitches.

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

Upon the experience of our gas technicians, most of the time, this issue is caused by either a problem with a power,  gas,  gas igniter,  burners, or in rare cases, a temperature control thermostat.

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 section, our experts have endeavored to provide you with straightforward, step-by-step instructions, and we are confident that they will guide you in identifying the root cause of the issue and rectifying it, allowing you to resume using your oven promptly. Nevertheless, if at any point you sense that the task is beyond your expertise, it’s advisable to entrust it to a qualified third party. Why risk burns or more severe mishaps? If you decide to tackle the fix on your own, be prepared with the necessary tools and replacement parts. Regardless of your chosen approach, swift action is essential because this problem won’t resolve itself and will significantly disrupt your daily routine until addressed.

  • Check the Oven Power Supply

    Begin by ensuring that your oven is receiving power. Despite being gas-powered, your oven still relies on electricity for the timer and other essential components. If the circuit breaker is functioning correctly, test the oven in a separate power socket to verify its operational status. In case of a faulty power outlet or socket, it’s imperative to seek replacement from a qualified electrician.

  • Check Gas Valves

    Examine the gas supply to ensure there are no obstructions preventing it from reaching your oven. Confirm that the main gas valve is turned on; if not, switch it back on. Check all other gas supply valves, including those on the branch lines. If everything appears to be in order, proceed to the next step.

  • Check Igniters

    The most common cause of an oven malfunctioning while the stove functions properly is often the igniter. Over time, the igniter may wear out or break for various reasons. Look for signs of damage or discoloration on the igniter coil and element; if present, it suggests a potential need for replacement. If the igniter functions correctly, the issue may lie with another faulty component.

  • Clean Burners

    If the gas igniter is operational, consider that the gas elements or burners could be obstructed. Remove them, inspect for any blockages, and clean them thoroughly. Reinstall the elements into the oven and check if this resolves the problem. If not, proceed to the next potential issue.

  • Check Worn Thermostat and Thermocouple

    Examine the temperature control thermostat and thermocouple if the root cause remains elusive. These components monitor the oven’s internal temperature and activate the heat when it drops too low. A defective temperature control thermostat can prevent the oven from turning on. Although this occurrence is rare, if the igniter is functional, consider replacing the temperature control thermostat to see if it resolves 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.

Let’s discover how the gas oven works

When selecting the bake or broil function in a gas oven, the control sends 120 volts of alternating current to the broil igniter, bake, or spark electrode. The igniter is linked to a safety valve, and as it heats up, it pulls an augmented current, or amps, through the valve. A bimetal arm inside the valve reacts to the heat produced by the amps, prompting the arm to flex and open, allowing gas to flow into the oven’s bake or broil burner tube.

Subsequently, the igniter or spark electrode ignites the gas, creating a flame to heat the oven. The igniter remains active to keep the safety valve open until the oven attains the specified temperature. A thermostat sensing bulb or an oven sensor monitors the temperature, and once the chosen temperature is achieved, the control discontinues the voltage to the igniter.

It’s essential to note that the temperature set by the control represents an average, and the actual temperature will fluctuate throughout the cycle. Convection ovens mitigate this fluctuation by utilizing a motorized fan to evenly circulate heated air throughout the oven cavity, with or without its heating element.

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.

Hello Sylvia Tinsley
Error code F31 on an oven typically indicates a temperature sensor or probe problem. The temperature sensor, also known as a temperature probe, is a component that monitors the oven temperature and sends signals to the control board. If the sensor is faulty or there is an issue with its wiring, the oven may display the F31 error code. You may need to inspect the temperature sensor and its connections to resolve this issue.

If you’re not comfortable doing this yourself, it’s recommended to contact Fix Appliances CA professional oven repair service for assistance. We can diagnose the problem more precisely and provide the necessary repairs or replacements.

My whirlpool oven stopped working a few months ago so I replaced the ignitor and the gas regulator. Worked fine for a few months and now it stopped again. The ignitor is working fine So I replaced the gas regulator again. But there is no gas going into the oven. Just see the ignitor clicking but no flame. Any advice?
Thanks in advance!

I have a crosley gas range 3 of the 4 burners work, we had rats get in it so we changed the hot surface ignitor it’s getting power but when you turn on the oven it beeps a few times and hits us with f3 error what will probably fix it lol

Hello Michael Thornhill,
The F3 error code on a Crosley gas range typically indicates a problem with the oven temperature sensor. Here are some steps you can take to troubleshoot and potentially fix the issue:

  1. Check the Oven Temperature Sensor: The temperature sensor is usually located at the back of the oven cavity. It should have a resistance within a certain range. You can use a multimeter to check its resistance at room temperature. If the reading is significantly off or if it shows as an open circuit, the sensor may need to be replaced.
  2. Inspect Wiring and Connections: Ensure all wiring connections to the temperature sensor are secure and not damaged. Sometimes, loose or damaged wiring can cause communication issues and trigger error codes.
  3. Reset the Range: Try resetting the range by unplugging it from the power source, flipping the circuit breaker off for a few minutes, and then turning it back on. This can sometimes clear error codes and reset the system.
  4. Replace the Oven Temperature Sensor: If the sensor’s resistance is out of spec or if it’s visibly damaged, you may need to replace it. Replacement sensors are often available from appliance parts stores or online retailers.
  5. Check for Other Issues: If the F3 error persists after checking the temperature sensor and wiring, there may be other underlying issues with the control board or other components. It might be best to consult a professional appliance repair technician for further diagnosis and repair in such cases.

Since you’ve already replaced the hot surface ignitor and are still encountering issues, the next logical step in troubleshooting the F3 error code on your Crosley gas range would be to focus on the oven temperature sensor and its related components.

Remember to always prioritize safety when dealing with electrical appliances. If you’re unsure or uncomfortable with any troubleshooting steps, it’s best to seek professional assistance.
