Oven and stove problems cover a lot of ground: an oven that never reaches temperature or burns everything, a gas burner that clicks and clicks without lighting, an electric element that stays cold, or a display that is dark or locked. Most are a single failed part, and a few are safety issues that should stop you cooking until someone looks.
This guide covers the usual causes for both gas and electric ranges, what you can check safely from the front of the appliance, the signs that mean leave the room and call, and what these repairs generally cost.
What you notice
- The oven preheats for a long time and never reaches the set temperature, or food is raw inside and dark outside.
- The oven bakes unevenly, or the broil element works but bake does not (or the reverse).
- A gas burner clicks repeatedly and does not light, or lights only on one side.
- An electric burner stays cold, heats only on high, or glows in one spot.
- The display is dark, shows an error code, or the control panel does not respond.
- A gas smell near the range, a yellow or orange flame instead of blue, or soot on pans.
Likely causes
A failed bake or broil element (electric oven)
The element breaks or burns through, often with a visible blister or split. The oven may take forever to preheat using only the broil element, or not heat at all.
A weak oven igniter (gas oven)
The igniter glows but does not get hot enough to open the gas valve, so the oven heats late, unevenly or not at all. It is the most common gas oven repair and wears gradually, so preheat times grow over months.
Clogged or wet surface burner ports and spark electrodes
After a boil-over or a cleaning, water and debris in the burner head keep gas from reaching the spark. The burner clicks without lighting. On sealed burners, a cap sitting crooked does the same thing.
A failed temperature sensor or thermostat
The oven relies on a probe to know its temperature. When it drifts or fails, the oven runs hot, cold, or throws an error code. On older ranges a mechanical thermostat does the same job and can be recalibrated.
A control board, relay or wiring fault
A dark display, a burner that will not turn off, or an oven that heats without being told to point to the electronics. Some control-panel lockouts are just a child lock or a self-clean latch that has not released.
A gas supply or pressure problem
If nothing on the range lights, the shutoff valve may be closed or the supply interrupted. A flame that is lazy and yellow across every burner points to supply pressure or a regulator, which is a job for the technician and the gas utility, not something to adjust at home.
Safe things to check before anyone comes out
- Note exactly which parts work: oven bake, oven broil, each surface burner, the display and the oven light. That map tells the technician a lot.
- Look at the burner flames on a gas range from a normal standing position. Steady blue flames are right; large yellow or orange flames, or soot on pans, are not.
- For a clicking burner, check from the front that the burner cap is sitting level and nothing has boiled over recently. Do not take the cooktop apart.
- Look through the oven window with the light on for a visibly split, blistered or broken element on an electric oven.
- Check the display for an error code, a lock icon, or a self-clean indicator that has not cleared.
- Place an inexpensive oven thermometer on the middle rack and compare it to the set temperature after a full preheat.
- Confirm the range is plugged in and other outlets on the circuit work. An electric range on a tripped double breaker may show a dark display.
- Write down the model number from the label at the oven door frame or in the drawer area if it is visible without moving anything.
When to stop and call
- There is smoke, a gas smell, sparking, or water near electrical parts. If you smell gas, do not touch switches or the range, open a door on your way out, leave the house and call the gas utility from outside.
- A burner stays on, or the oven heats when it is turned off. Have the range’s breaker or gas shutoff turned off if that can be done safely, and do not use it.
- Flames on a gas range are large, yellow or orange across the board, or you have headaches or a carbon monoxide alarm when the oven runs.
- You see sparks, scorching or melted insulation at the back of the range or at the outlet.
- The oven door is locked after a self-clean cycle and will not release, and the oven is still hot.
What the technician does
- Asks what works and what does not, checks the display and settings, and looks for a lockout or latch problem before anything else.
- Tests the oven element or igniter, the temperature sensor and the thermostat with a meter.
- Checks gas burner caps, heads, ports and spark electrodes, cleans or reseats them, and tests the spark module.
- Checks the incoming power on an electric range and, on a gas range, the shutoff valve, regulator and flame quality.
- Tests for gas leaks at the connections with a detector or leak solution whenever a gas range is worked on.
- Replaces the failed part, calibrates the oven if needed, and runs a preheat and a burner test.
- Explains what failed, how long the part should last, and any cleaning habits that will protect it.
What it usually costs
Oven and range repairs are usually part-driven. An igniter, bake element, temperature sensor or spark module with labor tends to come to the diagnostic fee plus a part and labor charge in the low to mid hundreds of dollars. Control boards and gas valves cost more, and on premium or dual-fuel ranges the parts alone can be substantial. The estimate should be explained before any work starts.
What moves the estimate
- Which part failed: elements and igniters are quick, control boards and gas valves are not.
- Gas versus electric, and whether gas-line work or a leak test is required.
- Brand and model, especially for commercial-style and built-in wall ovens.
- Access: wall ovens and slide-in ranges take longer to pull and reinstall.
- Whether the range needs to be recalibrated or multiple parts replaced at once.
Keeping it from coming back
- Clean up boil-overs on a gas cooktop after the burner cools, and let burner caps and heads dry fully before using them.
- Avoid lining the oven floor with foil; it blocks airflow and can damage the element and the sensor.
- Use the self-clean cycle sparingly. The high heat is hard on elements, locks and electronics.
- Keep the oven thermometer in place and note when preheat times start to creep up; a slow igniter is cheaper to replace before it fails on a holiday.
- Have a carbon monoxide alarm near the kitchen and sleeping areas if you have any gas appliances, and test it monthly.
- Keep flammable items such as towels and paper off the cooktop and away from the back of the range.
Questions people ask
My gas burner clicks but will not light. Is that dangerous?
Not usually, as long as you turn the knob off and the smell clears. It is most often moisture or debris in the burner. If gas smell lingers, or every burner is affected, stop and call.
The oven runs hot or cold by 25 degrees. Can that be fixed?
Yes. Many ranges can be recalibrated through the control panel, and a drifting temperature sensor is a routine replacement. Tell the technician what your oven thermometer shows.
Should I repair or replace the range?
Igniters, elements, sensors and spark modules are worth repairing on most ranges. A control board on an older basic range is where the math gets close. Ask for the estimate and compare with a comparable new unit.
Can I keep using the cooktop while the oven is broken?
If the cooktop works normally, has no gas smell and the oven is simply not heating, most technicians will say yes until the visit. If anything smells, sparks or stays on, stop using the whole appliance.
