What stops an oven from heating
An electric oven heats with a bake element on the floor, or hidden beneath it, plus a broil element up top. When the bake element burns open, often with a visible blister or split, the broil still glows but the oven never reaches temperature. In a gas oven, the glowing igniter does two jobs: it lights the gas, and the current it draws warms a bimetal strip inside the safety valve. As the igniter ages it can still glow orange yet draw too little current to open that valve, so the oven stays cold or takes ages to catch. Both types read the cavity with a temperature sensor whose resistance rises as it warms. A sensor out of range makes the control shut down or overshoot.
Gas is the main heating fuel in a large share of South Sound homes, so gas ranges are common on PSE lines, and propane shows up on the unincorporated edges. A gas oven still needs household power for its igniter and control, so it goes cold during a windstorm outage even with the gas on, and the surge when power returns can damage the control board. Electric ranges run on a 240-volt double-pole breaker; if one half trips, the clock and oven light keep working while the elements stay cold. The ovens we open range from older wall units in Wildwood and Carlyon along Capitol Boulevard, to ranges in Braemar and Canterbury ranch houses, to newer slide-ins off Littlerock Road in Tumwater.
Cold oven: symptoms and likely causes
| Symptom | Most likely | Safe for you to check? | Our fix |
|---|---|---|---|
| Gas igniter glowing orange, burner never lights | Aging igniter pulling too few amps for the valve | No, leave the gas oven closed up | Measure igniter current with an amp meter, replace it if low |
| Electric broil works, bake stays cold | Bake element burned open, often blistered or split | Yes, look for visible damage once it’s cool | Meter element resistance and replace it from truck stock |
| Temperature off, or an error code showing | Oven temperature sensor reading out of range | Yes, compare with an oven thermometer | Check sensor resistance at room temperature and at the control |
| Clock and light work, nothing heats (electric) | One half of the 240-volt range breaker tripped | Yes, reset the breaker fully off, then on | Confirm voltage at the terminal block, then trace any fault |
| Dead right after a self-clean cycle | Thermal fuse or control relay failed from the heat | No, nothing beyond a breaker reset | Meter the fuse and relay outputs, then replace the failed part |
Safe checks before you call
- Make sure the oven isn’t locked, set to delay start, or left in a showroom demo mode.
- After an outage, set the clock; some ovens refuse to bake until the time is entered.
- Look in the panel for a range breaker sitting halfway, and switch it fully off, then on.
- On a gas range, see whether the cooktop burners light, which shows gas is reaching the range.
- Set an oven thermometer on the middle rack and compare its reading with the display.
- Skip the self-clean cycle right before a big cooking day; that heat stresses fuses and boards.
When to put the oven in our hands
Stop and book if a gas oven glows but won’t light, if an electric element sparked or split, or if the breaker trips again after a reset. If you smell gas at any point, leave the house and call PSE from outside before anything else. Otherwise the visit starts with a meter: igniter current, element resistance, sensor reading and voltage at the control. You hear in ordinary words which part quit, and the price is on paper before we touch anything. Approve it, and that total already carries the $99; decline, and $99 covers the whole visit.
Asked about this problem
Why does my gas oven glow but never light?
In most gas ovens the igniter also opens the gas safety valve by drawing current through it. As it ages, it can glow bright orange while its current falls below what the valve needs, so no gas flows. It looks like it’s working, which is why the meter matters. A weak igniter is one of the most frequent gas oven repairs, and the part usually rides on the truck.
My electric oven heats but runs well off temperature. Is that a part?
Often it is the temperature sensor, the thin probe at the back of the oven cavity. Its resistance changes as it warms, and when it drifts the control misreads the heat. Check with an oven thermometer first, since many ovens also allow a small calibration adjustment in the settings. If the error is large or keeps changing, the sensor or the control needs testing.
Will a gas oven work during a PSE outage?
Most modern gas ovens won’t. The igniter and the electronic control both need household power, so the oven stays cold even though gas still reaches it. Don’t try to light the oven by hand. When power comes back, if the oven still won’t heat, set the clock and check the breaker, then book a visit in case the surge damaged the control.
Do you repair wall ovens in Olympia and Lacey?
Yes. We work on single and double wall ovens, full-size and slide-in ranges, and cooktops, in gas, propane and electric, across Olympia, Lacey and Tumwater. Wall ovens take a little more care to ease out of the cabinet, and we come prepared for that. Brands include Whirlpool, GE, Café, KitchenAid, Bosch, Frigidaire, Electrolux, Maytag and Samsung.
Is it worth fixing an older oven?
Usually, if the cabinet, door hinges and control are sound. Most no-heat failures come down to a single part: an igniter, an element, a sensor or a fuse. We name that part and write out a single price, and when an oven isn’t worth the money, we tell you so. The choice stays yours, made on measured readings rather than a hunch.
