If your gas stove burners work but the oven doesn't heat up, the most common culprit is a faulty oven igniter. Because the stove top and oven use completely different ignition systems, one can function perfectly while the other fails.
To reset a gas oven, perform a hard power reset by unplugging the oven or turning off the dedicated circuit breaker for 3 to 5 minutes. This will clear temporary control board glitches, reset the clock, and clear most basic error codes.
To determine if your gas oven ignitor is bad, turn on the oven and watch the ignitor (located near the bottom burner). If it never glows, glows dull orange instead of bright white, or glows for over 90 seconds without the gas lighting, the ignitor is failing and needs to be replaced.
To determine if your oven's thermal fuse is blown, check if the appliance is completely unresponsive (no power/display) or refuses to heat. Since the fuse rarely shows physical damage, the definitive test is a continuity check using a multimeter.
Replacing a gas oven igniter typically costs between $150 and $325 total for parts and professional labor. If you choose to hire an appliance repair technician, the breakdown generally includes:
Fixing a gas oven is usually worth it if the appliance is under 15 years old and the repair cost is less than 50% of a new unit. Common, inexpensive fixes like replacing a glow bar igniter ($150–$400) or a bake element will easily add years of life.
Yes, you can absolutely replace an ignitor yourself. Whether it is for a gas oven or a furnace, it is a very common and straightforward DIY repair that requires basic tools like a screwdriver and wire strippers.
At 7 years old, an oven is right on the bubble. Generally, if the repair cost is less than 50% of the price of a brand-new comparable oven, it is financially worth fixing. Otherwise, it is usually smarter to replace it, as the appliance is nearing the back half of its expected 10-to-15-year lifespan.
Blown fuses
Both gas and electric ovens use a thermal fuse to help keep the oven from overheating. If this fuse blows, the oven will not turn on because there is no safety measure.
You usually need an appliance repair engineer or a domestic electrician. Many faults (heating elements, thermostats, fans, control boards) are best handled by an appliance repair specialist, as they're trained to diagnose and repair specific oven components.
Oven igniters typically last 3 to 5 years under normal, daily use, though they can last up to 8–10 years with infrequent use. Because they are considered a "consumable" part that gets extremely hot, they wear out over time, making them the most common cause of gas oven heating failure.
Yes, you can manually ignite a gas oven, which is a great trick during a power outage or when the electric igniter fails. However, this only works for gas ovens; never attempt to light an electric oven manually. Always check your manufacturer's instructions for your specific appliance.
To clean a clogged or dirty gas stove igniter, first unplug the stove and let it cool. Locate the small ignition port or gas hole, and use a paperclip, needle, or toothpick to gently clear any trapped food or grease. Next, gently wipe the igniter's metal tip with a cotton swab dipped in rubbing alcohol to remove carbon buildup.
Why is my gas oven not heating up?
The specific button used to reset depends on the device, but it is most commonly the Power button. On many electronics, pressing and holding the power button for 5–10 seconds forces a restart.
Answer: Yes, it is generally safe to light a gas oven with a lighter as long as proper safety precautions are followed. Before lighting the oven, ensure there are no gas leaks, follow the manufacturer's instructions carefully, and keep children and pets away from the area.
A blown oven thermal fuse is a built-in safety mechanism designed to cut power if the appliance overheats. The most common symptoms include an oven that fails to heat up, a completely dead display console, or an oven that shuts off mid-cycle and won't turn back on.
Occasionally, resetting your gas oven's power can resolve the problem. Resetting the power involves the following steps: Turn off the unit by powering off the circuit breaker(s) for at least one minute. Turn on the unit by powering the circuit breaker(s).
When your oven is over 20 years old, you'll likely want to replace it when it needs a repair costing more than $500. After 20 years, replacement parts often start becoming scarce and the oven may continue to have failures as additional parts begin to wear out.
The most common oven problem is failing to heat properly (either not heating at all or failing to reach the set temperature). This is typically caused by a burnt-out electric heating element, a faulty gas igniter, or a malfunctioning temperature sensor.
A bad gas oven igniter generally shows itself through delayed ignition, extended preheat times, a faint glow, or the oven not heating at all. Because these parts weaken over time, they often glow a dull orange but cannot pull the required amperage to open the safety gas valve.
Replacing a gas oven igniter typically costs between $150 and $325 in total. The breakdown of this cost depends on whether you hire a professional or tackle the repair yourself:
