However, before you panic and call a repairman, it’s crucial to identify the underlying issue. Heating failure is a common oven issue, so here we’ll explore some common reasons your gas oven isn’t heating up and provide you with solutions to get it working again.

As you go through this article, you’ll be better equipped to troubleshoot your gas oven and get it working again in no time. So keep reading, and prepare to cook up a storm before you know it.

Why Is Your Gas Oven Not Heating?

Before you can start considering how to fix your oven, you first need to know the root cause of the problem. There are quite a few potential causes – here’s what you need to look out for.

1. Gas Supply Not Connected

One of the simplest and most common reasons your gas oven may not be heating up is due to a disconnected gas supply. If your oven has been moved or disconnected from the gas supply, the gas won’t flow and won’t be able to heat up.

To check if this is the issue, you can look for a gas shut-off valve, typically located behind the oven. See that the valve is turned on and the gas supply is connected; if you’re unsure, it’s best to contact a licensed professional.

2. Faulty Gas Line

It’s also possible that there’s an underlying issue with your gas line. This could be caused by a few potential problems, including a gas leak or a damaged gas line.

If you suspect a faulty gas line, do not try to fix it yourself, as this can be dangerous. This is a serious issue and will require the assistance of a professional.

3. Igniter Issues

Unlike an electric oven, a gas oven needs an igniter to start heating. It’s possible that the gas igniter may have gone bad or become faulty, preventing your oven from heating up.

This is another very common and straightforward issue – a faulty igniter can typically be identified by a lack of clicking sounds when you turn on your oven.

4. Malfunctioning Gas Valve

The gas valve is responsible for the gas flow into the oven, which is necessary to ignite the flame that heats the oven. If the valve is malfunctioning, it might prevent the gas from flowing properly, which can get in the way of your oven heating up to the right temperature.

The gas valve is a type of safety feature on your oven (also known as a safety valve), so if you suspect an issue with this component, it’s best to get in touch with a professional.

5. Broken Thermostat

Your oven’s thermostat regulates the temperature inside your oven cavity, heating it to the correct temperature. If the thermostat isn’t working correctly, it might not read the temperature accurately, resulting in your oven simply missing the mark.

A broken thermostat is a common issue with older ovens and can often be identified by a temperature that is significantly off from what you’ve set it to – it might even be too high, so watch out!

6. Dirty Burners

Over time, the burners in your oven can become dirty and clogged with food residue and grease, which can cause them to malfunction. It’s essential to clean your burners (and other oven components) regularly to ensure they function properly and heat your appliance effectively.

7. Tripped Circuit Breaker

You might also be dealing with a tripped circuit breaker. This is often the case when the oven suddenly stops working after a power outage or a surge. To check if this is the issue, look for the circuit breaker panel in your home and see if the switch for your oven is in the “off” position.

If it is, simply flip the switch back to “on.” If it continues to trip, it may indicate a more serious electrical issue that requires professional assistance.

8. Dislodged Temperature Sensor

The temperature sensor, which is different from the thermostat, is responsible for regulating the temperature and a constant oven temperature while you’re cooking.

If the sensor becomes dislodged or damaged, it may not accurately read the temperature, which can prevent your oven from heating up.

How To Fix A Gas Oven That’s Not Heating

Now that you’re aware of all the potential causes of the issues you’re dealing with, you’ll be better equipped to make a decision on how to move forward. We’ve combined some steps below that you can take to get your oven working again, depending on the root of the problem.

1. Check the Circuit Breaker

First of all, start with the simplest and easiest solution. Look for the circuit breaker panel in your home and see if the switch for your oven is in the “off” position.

If it is, simply flip the switch back to “on.” If it continues to trip, you might have a more serious problem, either with your oven or your home’s main electrical supply.

We recommend you contact an electrician to assist you, as this is a complex and dangerous issue that must be handled by a professional. 

2. Check the Gas Supply

Next, check the gas supply. If your oven has been moved or disconnected from the gas supply for any reason, it won’t be getting any gas.

Look for a gas shut-off valve typically located behind the oven. Ensure the valve is turned on and the gas supply is connected; if you’re unsure, it’s best to contact a qualified technician for help.

3. Check the Igniter

To check your gas oven igniter and igniter coil, you can look for them near the burner. Make sure that they’re clean and not damaged.

If they’re dirty, you can clean them with a soft brush, which might help solve the problem. However, you’ll have to contact a professional to get a replacement if there is any damage.

Unfortunately, a faulty igniter cannot typically be fixed, so you’ll need to get a new part.

4. Check the Burner

Next, you should inspect the burner, typically at the oven’s bottom. Always make sure the oven is disconnected from the power supply before performing any checks.

Make sure it’s clean, and look out for any food particles or dirt that might be blocking it. If it’s dirty, clean it gently with a soft brush and some warm water; gently clear away anything that might be blocking it, and then test to see whether your oven is heating up properly.

5. Check the Thermostat

The next thing to investigate is the thermostat. You can use an oven thermometer to measure the actual temperature in your oven to see if the thermostat is accurate or not.

If the temperature significantly differs from what you’ve set, it may indicate a problem with the thermostat. You can also use a multimeter to test this component if you have the right tools and skills.

Make sure that your oven is disconnected from the electrical supply first, though.

6. Check the Temperature Sensor

To check the temperature sensor, you’ll need to look for the physical component in your oven – it’s usually found at the back.

Ensure it’s in the proper position and securely in place; also, inspect it for any signs of damage or wear and tear. If there are any serious issues, the component must be replaced.

While you can purchase the part and do this yourself, it’s best to contact a professional repair technician. Make sure to get the correct replacement part for your oven model if you decide to do any repairs yourself.


How Often Should I Clean My Oven?

Cleaning your oven regularly is essential to keep it functioning properly. It’s recommended that you clean your oven at least once every three months. However, if you use your oven frequently, bake messy foods, or notice buildup, you may need to clean it more often.

A dirty oven can cause various issues, including a malfunctioning burner and thermostat. Ensure you follow the cleaning instructions in your user manual to clean your appliance safely and correctly.

How Often Should I Schedule Maintenance For My Oven?

It’s a good idea to schedule oven maintenance at least once a year. Regular maintenance can catch potential issues before they become bigger problems and ensure your oven functions correctly.

A licensed professional can perform a variety of tasks during maintenance, including cleaning the burners, checking the thermostat, and inspecting the gas lines. This will help you avoid issues such as heating and electrical troubles.

Can I Fix A Gas Oven That Won’t Heat Myself?

Yes, in certain cases, gas oven repairs can be easily done without professional help. However, if you’re unsure or uncomfortable with any of the steps, it’s best to contact a repair service for assistance.

Attempting to fix an issue that you’re not familiar with can lead to safety hazards or cause further damage to your oven, especially when working with gas. Always prioritize your safety and seek help when you’re in doubt.
