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.
