Most ovens in this city bake a casserole now and then for eleven months, and then cook for eight hours straight on one Thursday in November. That's the day a tired igniter or a cracked bake element finally gives up. It's also the week every repair company in Orange County is booked. Alpha & Omega is a family-owned shop that has worked in Orange County since 2005, based in Irvine, so an oven call from Old Town or Tustin Ranch is a short run for us. Call (310) 600-8152 and have the brand and the model number ready.

Which oven do you have? In Tustin that depends on the decade

Tustin was built in waves, and each wave left a different kind of cooking equipment behind. Knowing the neighborhood tells us a lot before we pull into the driveway. There's more on how the city breaks down on our Tustin service area page.

Old Town and the streets off Main and El Camino Real

The 1920s through 1950s houses here have been remodeled once or twice, sometimes three times. What that means for us is a mix: a 2015 slide-in range sitting in a kitchen whose gas line and 120-volt outlet date to a much older era. Gas ranges dominate. The common calls are a burner that clicks and won't catch, a glow-bar igniter that has gone slow, and oven doors that no longer seal because the hinges have been sprung by thirty years of use. Kitchens in these houses are small, so a freestanding range usually has to come out through a doorway, and we plan for that.

Tustin Meadows, Peppertree, Laurelwood and Tustin Village

These 1960s and 70s slab tracts are on their second or third set of appliances. A good number still have the original cutout geometry: a 30-inch opening for a drop-in or slide-in range whose lip rests on the countertop, or a single wall oven in a 24 or 27 inch cabinet opening. That's the practical reason we push repair here. Modern replacements don't always match the old opening, and a mismatch turns an appliance purchase into counter and cabinet work. Elements, igniters, sensors, valves and spark modules are ordinary parts, and fitting one leaves your counter alone.

Tustin Ranch

Late 1980s and 1990s construction with big kitchens, usually a single or double wall oven plus a separate cooking surface. Those wall ovens are now 25 to 35 years old, which is exactly the age where failures start arriving in sequence: a bake element, then the temperature sensor, then the door latch. The good news is these are all standard parts and the ovens are mechanically simple. The bad news is nobody thinks about a 30-year-old oven until the turkey is thawing.

Tustin Legacy, Columbus Square, Columbus Grove, Greenwood, Levity

Built on the old MCAS Tustin land in the 2010s and 2020s, mostly all-electric around heat pumps, with builder appliance packages where the refrigerator, the ovens and the hood all came from one manufacturer. These ovens rarely wear out. They fail electronically. Touch panels that stop registering a press, relays on the control board, convection fan motors, temperature sensors that drift, and door lock motors that stick after a self-clean cycle. If the house is only a year or two old, check the manufacturer warranty before you pay anybody, including us. Our page on appliance warranties explains what to look for on the paperwork.

North Tustin, Cowan Heights, Lemon Heights

Up the hill the lots get big and the kitchens get serious. Double wall ovens, 48-inch pro ranges with a griddle, warming drawers, steam-assist ovens, and often a second oven in a butler's pantry. Pro ranges are built to be worked on, and parts are available, but the diagnosis takes longer because there's more of everything: six or eight burners, two cavities, two convection fans. We budget more time for a first visit in these homes rather than rushing it.

Why won't my gas oven heat?

Nine times out of ten it's the igniter, and it's usually still glowing when you look at it. A glow-bar igniter has to draw enough current, roughly 3.2 to 3.6 amps on most models, to open the safety valve. As the bar ages its resistance climbs, the current drops, and the valve opens late or stops opening at all. The bar still glows orange, so it looks fine from the front. That's why a weak igniter gets misdiagnosed as a gas problem.

• Takes 30 minutes or more to preheat. Weakening igniter, far and away the most common gas oven call we get in the fall.
• Igniter glows, no flame ever arrives. Same part, further gone. Less often the safety valve.
• Lights, goes out, relights, over and over. Could be a borderline igniter. Could be normal cycling if the temperature is actually holding. An oven thermometer settles it in twenty minutes.
• A bang or a whoomp when it lights. Stop using the oven and read gas smell and delayed ignition first. Delayed ignition means gas is pooling before it catches.
• Burners click but won't light. Usually a burner cap sitting off-center after cleaning, a wet or clogged port, or a cracked spark electrode. Gas range burner problems covers the safe checks.

If SoCalGas has already been out, checked the line and told you the appliance is the problem, what to do after the gas company blames the appliance explains what gets red-tagged and what we test when we arrive.

Electric and dual-fuel: what we actually find

• No heat at all, or heat only from the broil element. A burned-out bake element. On a lot of newer ovens the bake element is hidden under the oven floor, so you can't see the break and it has to be tested.
• Off by 25 degrees or more. A temperature sensor that has drifted. Most oven sensors read around 1,080 ohms at room temperature, and a sensor that reads well off that number is the answer. Many ovens also have a calibration offset in the settings menu, and the manual shows how to reach it. Oven temperature problems has the thermometer test that tells a calibration issue from a failing sensor.
• Uneven baking, worse with convection on. A convection fan motor or a convection element that has quit. The oven still heats, so it doesn't feel like a failure.
• Dead display, no response. Breaker first, then a thermal fuse that opened, then the control board. Why an oven won't turn on walks it in order.
• Door locked and won't release after self-clean. A door lock motor or switch that didn't finish its travel. Don't force it, you'll break the latch assembly and turn a small part into a big one.

The full walkthrough of heat failures, igniters through control boards, is in why an oven stops heating.

One cavity works, the other doesn't. Is the board bad?

Probably not. A double wall oven has two cavities running off one control. If one cavity heats normally, the control is at least partly alive, so the odds favor the element, the sensor or the relay for the dead cavity. I'd test those three before I'd quote a board.

Double ovens do have to come partly out of the cabinet to reach the wiring and some components. That's a two-person lift on most models, and we lay protection on the floor and the cabinet faces before anything moves.

Hard water and steam ovens

Tustin tap water is hard, and that matters for one piece of cooking equipment in particular. Steam and steam-assist ovens fill from a reservoir or a plumbed line, and the scale builds inside the boiler and the water lines. The oven gives you less steam, then it throws a water or descale fault, then the pump or the level sensor fails. These ovens have a descale cycle for exactly this reason, and on Tustin water it's worth running on the short interval in the manual rather than the long one. We see the same scale pattern on refrigerator water valves here, which is covered on our Tustin refrigerator repair page.

What you can safely check before you call

• The breaker. Electric ovens and ranges run on a double-pole 240-volt breaker. One half can trip while the other holds, which leaves the display lit and the oven cold. Flip it fully off, then on.
• Control lock, delay start, Sabbath mode. Any of the three makes a working oven look broken. The manual for your model shows the key combination.
• The clock, if the power went out. Some electronic ranges will not accept a bake command until the time is set.
• The real temperature. Put a cheap oven thermometer on the middle rack, bake at 350°F for 25 minutes, read it. That one number saves us time on the phone.
• Burner caps and grates on a gas range. Seat the cap properly and let the ports dry if you've just cleaned them.

What not to do

• Don't light a gas oven by hand, and don't keep retrying an oven that won't catch. Each attempt puts more unburned gas in the cavity.
• If you smell gas, don't touch light switches. Get out and call SoCalGas from outside the house.
• Don't run self-clean in the weeks before Thanksgiving. The cycle runs the cavity near 900°F, and that heat is what finishes off a weak thermal fuse, door lock or control. Should you self-clean before Thanksgiving goes through it, and the short answer is no.
• Don't line the oven floor with foil. It blocks airflow and skews what the sensor reads.
• Don't pull a wall oven out of its cabinet or open the control panel. Live 240-volt wiring and gas connections are technician work.

When the power goes out in the foothills

North Tustin, Cowan Heights and Lemon Heights lose power more often than the flats, between wind events and utility shutoffs during fire weather. Ovens notice. A hard power loss during a bake cycle can leave a blank panel, a stuck latch or a cleared clock, and a surge on the way back up can take out the control board or open a thermal fuse. Before you assume the worst, cycle the breaker fully and set the clock. If the panel is still dark after that, something electrical needs testing, and that's a service call rather than a reset.

Thanksgiving in Tustin: the calendar is the real problem

Oven repairs are rarely complicated. What makes them stressful in late November is scheduling. Parts for mainstream brands usually land in a few days. Parts for built-in and pro-style ovens often ship from the manufacturer, and distributors slow right down the week of the holiday. A repair that's routine on November 1 becomes a scramble on the Monday before Thanksgiving, which in 2026 falls on November 23.

So test it now. Full preheat to 350°F, an hour of baking, a thermometer on the middle rack, and a sheet pan of biscuits to see whether the browning is even front to back. If anything looks off, call then, while the schedule still has room. And if it has already quit with guests on the way, what to do if your oven stops working on Thanksgiving Day has the triage list and the food-safety rules for a half-cooked bird.

Frequently asked questions

Can you get to Tustin the same day for an oven repair?

Usually, if you call in the morning. We're based in Irvine and run Jamboree and Irvine Boulevard into 92780 and 92782 several times a day, so Tustin is one of the easier cities on our route. November is the exception. The two weeks before Thanksgiving fill up, and if the day is full we say so on the phone instead of booking you into a window we can't keep.

My range sits in an old drop-in cutout from the 1970s. Can it be repaired instead of replaced?

Almost always worth trying first. A drop-in rests on the countertop lip in a cutout sized for that model, and the selection of modern drop-ins is thin. Replacing one often turns into counter and cabinet work. Igniters, elements, sensors, spark modules and valves are routine parts, so repairing what you have leaves the counter alone.

One burner on my pro-style range won't stay lit. Does the whole range need work?

No. On a sealed-burner range each burner has its own electrode and its own path through the spark module or the safety valve. A burner that lights and then drops out points at that burner: a dirty or cracked electrode, a clogged port, or a weak thermocouple on ranges that still use standing pilots. The other burners and the oven are separate systems.

The power went out and now my oven display is blank. Is the control board dead?

Not necessarily. Start at the breaker, because one half of a double-pole 240-volt breaker can trip while the other stays closed. Then check whether the clock needs setting. If the breaker is fine and the panel is still dark, a surge during the outage can take out the board or open a thermal fuse, and that needs testing.

What does oven repair cost in Tustin, and is the work guaranteed?

You get a free estimate over the phone, and the technician quotes the repair on site before any work starts, so you approve the price before anything is touched. Every repair carries a 90-day parts and labor warranty.
