- Restore the power supply and test the oven to ensure the new thermostat is functioning correctly.
Reason #4: Incorrect Temperature Calibration
Sometimes, a gas oven may not heat properly due to incorrect temperature calibration.
If the oven is not calibrated correctly, it may not reach the desired temperature or maintain a consistent temperature throughout the cooking process.
Ways to Calibrate the Temperature
To calibrate the temperature of your gas oven, follow these steps:
- Preheat the oven for at least 30 minutes.
- Use an oven thermometer to measure the actual temperature.
- Adjust the temperature dial or control panel settings to match the desired temperature.
- Repeat the process several times to ensure accurate calibration.
Tips to Ensure Proper Temperature Calibration
- Regularly check and adjust the oven temperature calibration to ensure accurate cooking results.
- Use an oven thermometer to monitor the actual temperature inside the oven.
- Avoid opening the oven door frequently, as it can affect the temperature and cooking process.
Reason #5: Malfunctioning Control or Relay Board
A damage control or relay board can also cause your gas oven to not heat properly.
The control or relay board is responsible for regulating the oven’s functions, including igniting the gas and maintaining the desired temperature.
If the control or relay board is faulty, it may not function correctly, leading to heating issues.
Indicators of a Faulty Control or Relay Board
- The oven fails to heat up.
- The control panel or digital display shows error codes or malfunctions.
- The oven’s functions, such as preheating or self-cleaning, don’t work correctly.
Steps to Diagnose and Repair the Control or Relay Board
To diagnose and repair a faulty relay or control board, it is recommended to seek the assistance of a professional appliance repair technician.
They have the knowledge and tools to diagnose the issue accurately and replace the faulty board if needed.
Other Troubleshooting Steps for a Gas Oven That Won't Heat
Check the Gas Supply and Service Cut-Off Valve
- Make sure the gas supply to the oven is turned on.
- Locate the service cut-off valve and ensure it is fully open.
- If the gas supply seems to be functioning correctly, move on to the next step.
Test the Safety Gas Valve
- Use a multimeter to test the continuity of the oven igniter.
- Replace the igniter if it shows no continuity.
- If the igniter is working properly, test the safety gas valve for continuity.
- Replace the safety gas valve if it doesn’t show continuity.

FAQs on Gas Oven Issues
If your gas stove is working, but the oven is not heating properly, several factors could contribute to the issue.
One common culprit is a malfunctioning igniter. The oven’s igniter plays a crucial role in initiating the heating process.
If it’s faulty, the oven may not reach the desired temperature or may fail to heat at all.
Additionally, problems with the gas safety valve, issues related to the oven thermostat, or a defective bake or broil element could also be responsible.
To troubleshoot, you can inspect these components, check for visible signs of defects.
If your gas oven occasionally fails to light, the most common culprit is a faulty igniter.
The igniter is a critical component that ignites the gas released by the oven’s safety valve, initiating the heating process. Over time, igniters can wear out or develop cracks, leading to inconsistent ignition.
Additionally, a weak or malfunctioning igniter may struggle to reach the necessary temperature for the gas valve to open fully.
To address this issue, consider inspecting the igniter for signs of wear or damage. If you notice any issues, replacing the igniter is a common and effective solution to ensure reliable ignition in your gas oven.
Determining whether your gas oven igniter is faulty involves assessing several factors.
Firstly, observe the oven during the ignition process. If the oven’s pilot flame fails to ignite within a few minutes, it could indicate a malfunctioning igniter.
Additionally, inspect the igniter for visible signs of damage, such as cracks, blistering, or irregularities in its appearance. If the igniter appears discolored or worn, it may be a clear indication of a problem.
You can also use a multimeter to measure the igniter’s resistance. A properly functioning igniter should typically have a specific resistance range, and a reading outside this range may suggest a faulty component.
If you suspect the igniter is bad, considering its role in lighting the pilot flame, replacing it is a recommended step to ensure consistent and reliable ignition in your gas oven.
