Kenmore gas oven not working: what it means and what to check

If your Kenmore gas oven won't bake, won't broil, or the cooktop still works while the oven stays cold, the failure is usually in the oven ignition circuit. This page helps you sort out a simple supply or setting issue from a failed igniter, safety valve, sensor, or control board.

Straight answer

A Kenmore gas oven not working usually means the oven isn't lighting or the control isn't sending power to the bake or broil ignition circuit. The single most common cause is a weak or failed oven igniter, especially when the cooktop burners still light normally.

Check these first

Safe to do yourself. Unplug the appliance before you start.

  1. Stop if you smell gas

    If you smell gas, don't try to relight the oven, don't flip switches, and leave the area. Call the gas utility, emergency services, or a qualified gas technician from a safe location.

  2. Check the cooktop burners

    Light a surface burner. If the cooktop won't light either, treat this as a gas supply, shutoff valve, or regulator problem before blaming the oven.

  3. Try broil, then bake

    Set broil and watch for heat. If broil works but bake doesn't, the bake igniter is the likely path to test. If both bake and broil fail, the safety valve, wiring, or oven control moves higher on the list.

  4. Look or listen for oven ignition

    Set the oven to bake and look through the lower oven area for a red or orange glow on glow-bar models, or listen for oven sparking on spark-ignition models. You shouldn't need to remove panels for this check. No glow or spark points toward the ignition circuit, and a glow with no flame can still be a weak igniter.

  5. Check for lock or control-panel symptoms

    If the display is blank, locked, beeping, or showing an error, the oven may be blocked by a control, latch, sensor, or board fault. Try canceling the cycle and resetting power at the breaker once, then test bake again.

Electric ovens bake with an element on the floor, hidden under a floor panel on many newer models, and broil with one at the top. The temperature sensor is the thin probe on the upper back wall. Gas ovens light a burner under the floor panel with a glowing igniter.
When it's a repair

A technician usually tests the bake ignition system first, then the broil ignition system if the model has a separate broil burner and broil also fails, followed by the oven safety valve, wiring near the burner, the temperature sensor, and the electronic oven control. On Frigidaire-built Kenmore ranges, a failed relay or burned solder joint on the control can leave the oven cold while the cooktop still works. If the range is older, has heavy rust in the burner area, needs a control board plus a valve, or has repeated ignition trouble, replacement may make more sense than stacking parts into it.

Models where this shows up most

Kenmore 790 gas ranges are Frigidaire or Electrolux-built, so the ignition layout and many control-board faults follow Frigidaire service patterns. In the 790 family, it's common to see the cooktop working while the oven bake circuit stays cold. Other Kenmore prefixes can use different ignition designs, including spark ignition, so match tests to the model number.

Have the model number ready

The company will ask for it first. It's on a sticker or metal plate, usually in one of these spots:

Conditions that make this more likely

Boards fail earlier in hot rooms

Electronics are rated for room temperature. In a garage or an unconditioned laundry room in summer, a control board can sit well above that for hours a day. Before replacing a board, a good technician confirms the parts it controls test good, since a shorted pump or valve can take out a new board too.

What a technician tests

Most likely part first. These are for a technician with a meter and the tech sheet, not a weekend project.

PartHow it's tested
Bake ignition systemWith the unit set to bake, the technician checks whether the glow-bar heats or the spark system fires, and whether the burner lights during the ignition sequence. If nothing happens, the circuit is tested back toward the control; if a glow-bar igniter glows but the burner never lights, it can be too weak to open the safety valve even though it looks alive.
Oven safety valveIf the glow-bar igniter is drawing properly, or a spark system is firing, but gas never reaches the burner, the valve is tested as part of the ignition and valve circuit. If bake and broil both fail, the valve, a shared feed, or the control circuit becomes more suspect than a single bake igniter.
Electronic oven controlThe control is checked for a bake or broil output when the display is calling for heat. On some Frigidaire-built Kenmore boards, the failure shows as a relay click with no heat, a melted relay area, or a burned solder joint on the back side of the board.
Oven temperature sensorIf the oven heats only a little, overshoots, or shows sensor-related faults, the sensor is checked against the tech sheet for the model. A sensor that reads out of range can keep the control from running the bake circuit properly.
Thermal fuse or high-limit fuseIf the model uses a thermal fuse, the technician tests it for continuity with power disconnected. An open fuse won't reset and has to be replaced, though this is less common than an igniter failure.

Common questions about appliance repair

Can I reset a Kenmore gas oven that won't work?

Yes. Turn the oven off, reset power at the breaker once, then try bake again. If the same symptom returns, repeated resets won't fix a weak igniter, valve, sensor, or board.

Why does the igniter glow but the oven won't light?

A glowing igniter can still be weak. On a glow-bar gas oven, the igniter has to get hot enough and draw enough current for the safety valve to open. Spark-ignition models use a different test.

Why does the stove part work but the oven doesn't?

The cooktop and oven use different ignition paths. Normal surface burners prove the range has gas, yet the oven can still have a failed bake igniter, bad valve, broken wire, or board output fault.

Is this different on Kenmore 790 models?

Yes, many 790 models are Frigidaire-built. That matters because the tech sheet, igniter style, safety valve circuit, and control-board layout follow Frigidaire parts and service logic.

Should I replace the igniter myself?

Leave the diagnosis to a technician if the igniter glows with no flame, if the model uses spark ignition, or if both bake and broil fail. Igniter access can mean removing oven panels and working near gas and wiring, so don't keep swapping parts without tests.
