You’re getting ready to bake these cookies with chocolate chips for a movie night alongside your friends on this beautiful summer evening. You purchase all the necessary materials, combine the recipe, place the cookie dough in the oven, and start cleaning the kitchen while you wait for the scent of freshly made cookies to fill the room. 

But when you return to look at your cookies, you discover a problem. Even when the switch is on, the oven hasn’t heated up when you open the door. What are your next steps?

This article will discuss the typical causes of your gas oven not heating up, how to fix oven problems quickly, and when to get a professional oven repair service in Nashville TN. Let’s first examine how gas ovens work.

How Gas Oven Works

How gas ovens work

When the knob is turned on, what happens in your gas oven? Let’s look at some of its parts and their functions to understand better how a gas oven works.

  • Oven burner. The area on the stovetop is where you set your cooking utensils and pots to cook food.
  • Pilot flame. Older gas oven models exhibit this, as the stovetop features an electric ignition generator instead of a continuously burning flame.
  • Spark generator. This portion of the gas oven produces a spark to ignite the gas and cook a meal.
  • Thermostat. Thanks to this internal temperature-measuring gadget, you can regulate the precise temperature at which your oven warms.

These are the fundamental parts of every gas oven. We’ll now assist you in comprehending how these components interact.

You open the safety valve, which lets gas into your appliance from the main supply line as you turn on the knob in your gas oven. The gas is then ignited to light the burner when you click the ignition button, which causes a spark to be produced.

The spark electrode in your gas oven receives current when you decide to bake something. A safety valve protects this electrode. The oven’s thermostat regulates the temperature inside to keep it from heating up too much. The safety valve will shut itself down, cutting off the gas supply in the oven when it reaches the proper temperature. The heating then resumes when the temperature drops and the safety valve reopens. When the timer on your oven runs off, and you turn off the knob, this cycle keeps the oven at the ideal average temperature. 

Now that you understand how a gas oven operates, let’s examine some potential causes for your oven’s failure to heat up.

Why Is My Gas Oven Not Heating Up?

There could be several reasons why your gas oven isn’t working correctly. However, to avoid accidents, remember to turn off the breaker on your gas oven before beginning your do-it-yourself project. To hire an appliance repair expert, contact Robs Appliance Plus if you lack the confidence to handle the problem yourself.

Let’s go over the top five reasons why your gas oven is not heating up.

The circuit breaker tripped

By definition, a circuit breaker serves as a safety device that, if a component of the circuit malfunctions, cuts off the electricity to your gas oven. 

Your gas oven won’t heat if a circuit breaker trips because it won’t get electricity from the power source. 

The following are a few reasons for circuit breakers tripping: 

  • Current overload
  • Faulty circuit breaker
  • Damaged wiring
  • Ground fault
  • Open current 
  • Damaged terminal block

A tripped circuit breaker may indicate a more serious issue. For example, the breaker might have tripped to cut off the current flow to prevent a fire if an electrical overload within your oven and your wires were in danger of burning out.

If the gas oven isn’t heating up, you might look for a tripped breaker valve at the bottom.

The following instructions can help you quickly reset your circuit breaker if it has tripped:

  • Turn off every appliance that is connected to the tripped wire.
  • Locate the circuit breaker box, then replace the “off” with the “on” switch.

Your circuit breaker should be reset after doing this. Once you turn on the appliance, if the breaker trips again, you may have a malfunctioning breaker switch or an underlying issue, such as broken wiring or an open current. Calling an expert in this situation to examine the damage is important.

The gas supply might not be connected

The lack of a gas supply could be another cause of your gas oven not heating up.

When you fire the gas in your gas oven using the igniter, it facilitates internal heating. When you hit the igniter switch on your gas oven, it might not receive gas, which could explain why it isn’t working. There are two potential reasons for this problem:

  • First, turn off your gas valve to switch off the gas supply to your appliance. To solve the issue in this instance, turn on the valve. You can manually switch it on by turning the lever on your gas valve, and it’s typically found next to your gas meter.
  • Secondly, regardless of whether the valve is switched on, your appliance might not get gas since there might not be a gas supply within your pipes.

Contact your gas supply provider to determine the reasons for potential disruptions in natural or liquid propane gas access due to various factors.

The temperature sensor might need to be relocated or replaced

Your gas oven may not heat up due to a malfunctioning oven temperature sensor.

When the oven’s internal temperature reaches the appropriate level, the temperature sensor controls the oven’s internal temperature and cuts off the gas supply. When your temperature sensor is broken, your appliance won’t heat up correctly or can not turn it on.

Locate the sensor first, then make sure it is positioned correctly. Your oven’s temperature readings will change if the temperature sensor comes into contact with the oven’s wall, which could cause improper oven heating. Check whether the issue is resolved by moving the sensor so it is no longer in touch with the oven walls.

Should the issue continue, it could result from damage to your temperature sensor. Contact a pro to replace or repair your temperature sensor in this case.

The oven control board might be malfunctioning

The oven’s control board may be an issue if you check out all of the previously mentioned possibilities. All of the knobs are on the control board, which you can examine for physical damage or indications of burning.

Oven board malfunctions might occasionally occur in the winter when the gas line is exposed to below-freezing temperatures. If this occurs, switch off all the knobs and let the oven cool down inside by leaving the door open for fifteen minutes.

Close the oven door and replace the knob after fifteen minutes. After doing this, your oven board should be reset, fixing the issue.

Possible broken burner igniter

One typical reason why an oven malfunctions is a malfunctioning igniter. The gas cannot light up or produce heat if the oven igniter malfunctions because the igniter produces a spark to light the gas. If an igniter’s coils burn off or get filthy, it may stop functioning.

You cannot use your gas stove or oven if the igniter fails. Even when the stovetop isn’t heating, you could smell gas if you switch on the stove. It indicates that your igniter is probably broken.

A malfunctioning igniter poses a significant risk of fire. Therefore, you should get a new one as soon as you can. The following are some guidelines for preserving fire safety when an igniter malfunctions:

  • If you smell gas, turn off the stovetop and the oven.
  • Wait until the gas smell has dissipated before lighting a match or lighter in the kitchen.
  • Kindly get your igniter fixed by an appliance repair professional.

You may also turn off the gas valve as an extra safety precaution until you repair the igniter or have a new part available.

When your gas oven isn’t heating up after trying all of the above fixes, or when you smell gas even after turning it off, it’s time to call a professional.
