Identify the fuel, then look
On an electric oven, look at the element while it is called for and check for a visible break. On a gas oven, watch the igniter: if it glows for more than a minute and no flame follows, the igniter has weakened even though it looks healthy. That single observation is the diagnosis on most gas ovens.
What you observe
- The oven never reaches temperature and the broil element does work — One heat source is dead and the other is not, which localises the fault immediately.
- A gas igniter glows and no flame appears — The classic weakened-igniter signature, and it looks exactly like a working part.
- A visible break, blister or bright spot on an electric element — Evidence rather than inference. Nothing further needs establishing.
- The oven heats but far too slowly — Partial heat, which points at one element of a pair or at a weak gas flame.
- The oven heats but the food burns or undercooks — A calibration or sensor question rather than a heating failure, and a different page.
- NEAR MISS: the display is dead and nothing responds — That is a control or supply question with its own page.
Ranked, split by fuel
- On gas: a weakened bake igniter — First for gas cabinets, and by a wide margin. These parts age by drawing less current over time, so they still glow while no longer opening the valve, which is why they fool people.
- On electric: a failed bake element — First for electric cabinets. It usually shows a break or a blistered section, and testing the broil element separately confirms the rest of the circuit is healthy.
- The oven temperature sensor — Second on either. A sensor reading wrongly makes the control stop calling for heat long before the oven is hot.
- The control relay that switches the bake circuit — Last. Real, less common, and only worth reaching for once the heat source itself is proven.
Fuel first, then watch
- Establish gas or electric by looking at the bottom of the cavity — A gas oven has a burner tube and an igniter; an electric one has an element. It decides everything else.
- Call for bake and watch what happens at the heat source — On gas you are timing the glow; on electric you are looking for a break. Both are observations, not tests.
- Try broil separately — If broil works and bake does not, the supply and the control are both proved healthy.
- Only then consider the sensor or the relay — Both need a meter and a panel off, and the checks above narrow which one matters.
What an owner can safely do
- Look into the bottom of the cavity and identify the heat source — A burner tube with a small ceramic igniter means gas. A visible coil means electric.
Tools: flashlightAbout 5 min
- Set bake and watch the element or the igniter from a safe distance — Do not reach in. You are looking, and the oven door can stay ajar for a short look.
About 10 min
- Time a gas igniter from first glow to flame — A glow that continues well past a minute with no flame is the finding this page turns on.
Tools: timerAbout 10 min
- Set broil briefly and see whether that heat source works — It separates a dead heat source from a dead oven in one step.
About 10 min
- STOP before removing the bottom panel or the rear cover — Both sit over live terminals or a gas connection, and that is where owner checks end.
Before anything is opened
Safety
Unplug the appliance or switch off its breaker before removing any panel, and note that a capacitor can hold a charge after the power is off. If you smell gas, do not switch anything on or off, leave the building, and call the gas utility or your local emergency number from outside; do not look for the leak yourself. Do not lean into a hot cavity to inspect an element, and leave the door lock as fitted, because on a self-cleaning oven it is a safety device.
Where the owner side ends
Call once you know the fuel and what happens at the heat source, because those two facts usually name the part before anybody arrives. Anything on the gas side beyond looking is a technician job. Call at once if the oven will not switch off, or if there is scorching at the rear, and leave the circuit off until it has been seen. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself.

What is not on this page
Written for the Whirlpool oven class rather than one family or fuel type. Element ratings, igniter references, sensor positions and panel removal differ by model and belong on the specific page for your cabinet. Where that page exists it is the more precise answer; this one is written from what you can see.
