You turn on the stove to boil water and the burner glows or the flame lights normally. Then you set the oven to 350°F, wait, and nothing happens. An oven stopped working but stove works situation can feel confusing, but it often points to a component that is unique to the oven rather than a whole-house power or gas failure.
Because the cooktop and oven share a range body but not every internal part, the working burners tell you something useful: the appliance is receiving at least some power or gas. The problem is usually isolated to the oven’s heating circuit, control system, safety device, or ignition path.
Why an Oven Can Fail While the Stove Keeps Working
Modern ranges are designed with separate subsystems for the cooktop and the oven. On an electric range, the surface elements may run through their own switches or a separate control board, while the oven relies on bake and broil elements, a thermostat, a thermal fuse, and a main control. On a gas range, the cooktop burners may use spark ignition, but the oven often uses a glow-bar igniter and a safety valve.
That separation is why one half of the appliance can work perfectly while the other half seems dead. A tripped breaker might kill only the oven circuit, a burned-out igniter might stop only the oven, or a failed relay on the control board might leave the stovetop untouched. Electric and gas models have different failure patterns, so identifying your fuel type is the first meaningful step.
How a Range Separates Cooktop and Oven Functions
In an electric range, the cooktop elements are often controlled by infinite switches or a separate touch panel. The oven, by contrast, depends on a bake element, a broil element, a temperature sensor, and a main board that sends voltage to the correct circuit. If the oven display works but the bake element stays cold, the issue could be the element, the relay, the sensor, or the wiring between them.
In a gas range, the cooktop burners and oven burner usually share the same gas supply, but they do not share the same ignition components. The cooktop may spark and light while the oven’s glow-bar igniter fails to pull enough current to open the safety valve. That means you can have a fully functional stovetop and a completely cold oven even though gas is present at the appliance.
Common Symptoms That Point to an Oven-Specific Fault
The most obvious symptom is an oven that stays cold while the stovetop burners heat normally. Other clues include a control panel that lights up but never reaches the set temperature, an oven that preheats partially and then stops, a broiler that works while the bake function does not, or an error code that appears only when you start the oven.
You might also hear clicking, smell gas without a flame, notice uneven baking, or see a bake element with a visible blister, crack, or break. If you smell gas at any point, stop using the oven, ventilate the kitchen, and call a qualified technician or your gas utility. A gas smell is not a do-it-yourself diagnosis situation.
Troubleshooting an Oven That Won’t Heat When the Stovetop Works
Before testing parts, make sure the range is safe to inspect. Unplug an electric range or turn off the dedicated breaker. For a gas range, unplug the electrical cord and shut off the gas supply valve if you plan to inspect internal components. If you are not comfortable working around 240-volt wiring or gas lines, stop and call a professional.
Next, confirm the exact failure: does the oven light turn on, does the display show the time, does the fan run, and does the broil element heat? These details narrow the problem quickly. A dead display suggests a control or power issue, while a working display with no heat points more toward an element, igniter, relay, or safety valve.
Basic Checks Before You Call a Technician
Start with the simple settings that are easy to overlook. Check whether the oven is in Sabbath mode, demo mode, control lock, or a delayed-start program. Make sure the timer is not set to turn the oven off, and confirm that the door is fully closed. A child lock or a recent power outage can leave the control board in a state that blocks heating even though the stovetop works.
Reset the appliance at the breaker for one to two minutes, then restore power and try the oven again. If the oven has a separate breaker or fuse, verify that it has not tripped. For electric ranges, test both bake and broil functions separately. For gas ranges, watch for the glow-bar igniter and listen for the click of the safety valve. If nothing glows or clicks, the problem is likely in the ignition circuit.
Testing Electric Oven Components Safely
On an electric oven, inspect the bake element for obvious damage such as cracks, bubbles, or a broken coil. With power disconnected, use a multimeter to test the element for continuity. A reading of infinite resistance means the element is open and needs replacement. You can also test the thermal fuse, high-limit thermostat, and temperature sensor according to your model’s service manual.
If those parts test normal, the main control board or a relay may be the culprit. A relay can stick open and stop sending voltage to the bake element, even though the stovetop still receives power. Control board testing requires live voltage checks, so it is best left to a technician unless you have experience with appliance electronics and proper safety gear.
Diagnosing Gas Oven Ignition and Safety Parts
Gas ovens commonly fail when the glow-bar igniter weakens. The igniter may glow orange but not draw enough current to open the safety valve, so gas never reaches the burner. If the igniter does not glow at all, it may be burned out, disconnected, or receiving no voltage from the control board. A failed safety valve can also prevent the oven from lighting even when the igniter glows correctly.
Because the stovetop works, you know gas is reaching the range, but that does not guarantee gas is reaching the oven burner. The oven has its own valve, tubing, and ignition sequence. Any repair that involves opening the gas line, replacing the safety valve, or adjusting the burner should be handled by a licensed technician for safety and code compliance.
Repair, Replace, or Call a Pro: Making the Right Call
Once you know the likely failed component, compare the repair cost with the age and condition of the range. A bake element or igniter is often an affordable fix, while a control board or sealed gas valve can be expensive. If the range is more than 12 to 15 years old and the repair costs more than half the price of a new model, replacement may be the smarter long-term choice.
Consider convenience and safety as well. A simple electric bake element may be a reasonable DIY repair for a confident homeowner. Gas ignition repairs, control board replacements, and any work involving 240-volt wiring are better left to a professional. A technician can also check for related failures that might cause the new part to fail again.
Repair vs. Replace Cost Decisions
Typical installed costs vary by region and appliance type. A gas oven igniter might cost $150 to $300 installed, an electric bake element might run $100 to $250, a thermal fuse might be $100 to $200, and a main control board might be $250 to $600 or more. These numbers help you decide whether the repair makes financial sense.
Also factor in parts availability, matching appliance finishes, and whether other features are already failing. If the oven has repeated breakdowns, rust, a damaged door seal, or inconsistent temperatures, replacing the range may be less frustrating than chasing one repair after another. If the rest of the appliance is in good shape, a targeted repair is often the better value.
Safety and Warranty Considerations
Safety should guide every decision. Gas leaks, carbon monoxide, electrical shorts, and overheated wiring are serious hazards. If you notice a burning smell, sparks, tripped breakers, or a gas odor, stop using the appliance immediately. Keep the area ventilated and contact a qualified service provider.
Check your owner’s manual and warranty before attempting repairs. Many manufacturers void coverage if unauthorized parts are installed or if the appliance is opened by someone who is not certified. Recalls and service bulletins may also apply to your model, so a quick check with the manufacturer can save time and money.
Preventing Future Oven Breakdowns
Keep the oven and stovetop clean, but avoid harsh chemicals on igniters, elements, and control panels. Do not line the oven floor with foil, because it can trap heat and damage the element or sensor. Check the door gasket periodically, and replace it if it becomes brittle or fails to seal, since heat loss forces the oven to work harder.
Use the self-clean cycle sparingly if your range has one, especially on older models, because high heat can stress electronic boards and igniters. A surge protector for the range outlet can also help protect sensitive controls. If the oven has already needed one major repair, schedule routine service before the next holiday cooking marathon.
If your oven has gone quiet while the cooktop still performs, use the working stovetop as a temporary backup and work through the checks that match your fuel type. The exact phrase oven stopped working but stove works usually means the range still has power or gas, so the repair is likely focused on the oven’s own heating or ignition system. With a careful diagnosis, the right part, and professional help when gas or high-voltage wiring is involved, you can get your kitchen back to full operation without replacing the entire range.
