An oven that won’t hold temperature ruins dinner and wastes groceries. We fix that. Most ovens fail in a handful of predictable ways. A bake element burns through. A gas igniter glows but never lights. A temperature sensor drifts and your roast comes out raw or charred. We see these same failures every week across San Diego County, from Chula Vista to Escondido. Here’s how we diagnose them, what parts usually fail, and where gas safety matters most.

Is your oven not heating? Here’s what it could mean

On an electric oven, the usual culprit is a burnt-out bake or broil element. You’ll often see a blistered spot or a clean break in the metal loop. A dead element won’t glow orange end to end. We test it with a multimeter for continuity. An open circuit means it’s done, and a new element drops in. If the element looks fine, we check the temperature sensor next. That’s the thin metal probe in the back wall, an RTD that should read close to 1,080 ohms at room temperature. If it reads way off, the control board gets bad data and the heat goes wrong. A blown thermal fuse can also cut power after a hot self-clean cycle.

On a gas oven, no heat almost always points to the igniter. It’s the bar-shaped or round glow-bar element that has to draw enough current to open the safety gas valve. Here’s the trap: a weak igniter still glows, so it looks fine, but it never gets hot enough to release gas. The oven sits cold while the igniter glows away. We measure the current draw on it. A healthy igniter pulls 3.2 to 3.6 amps; below that, the valve never opens and the part needs replacing. Other causes are a failed gas safety valve or a control board that isn’t sending the signal. Anything involving the gas valve or supply line is a job for a qualified tech, not a DIY fix. If your oven is not heating, it’s not a problem you should ignore. We even have a dedicated guide on oven not heating troubleshooting for common issues.

Gas vs. electric oven repair: what’s the difference?

Both ovens bake bread the same way, but the parts that get them hot are nothing alike. That changes how we diagnose and what’s safe to touch.

Electric Oven Repair Electric ovens make heat by pushing current through metal elements. The bake element sits at the bottom, the broil element up top, and many convection models add a third element ringed around the fan. When one fails, we pull power and test continuity and resistance with a meter to find the dead part. The fix is usually a new element, a new RTD temperature sensor, or the control board. It’s all electrical work, so the danger is shock, not gas, and we kill the circuit at the breaker before opening anything.

Gas Oven Repair Gas ovens burn natural gas or propane and need an ignition source to light it. The parts that matter are the glow-bar igniter, the gas safety valve, the burner tube, and the control board that ties them together. When a gas oven quits, the problem is almost always ignition or gas flow: a weak igniter that won’t open the valve, a failed safety valve, or clogged burner ports starving the flame. Gas oven repair in San Diego means working live gas, so we leak-check every connection with the right tools before we leave. If you ever smell gas, shut off the supply and call from outside. Our technicians handle both gas oven repair in San Diego and electric models.

Common oven issues we handle in San Diego County

These are the oven calls we run most across San Diego County. Each one has a short list of usual suspects, and that’s where we start:

  • Oven not heating: Bad heating element, igniter, or control board.
  • Uneven heating: Failing temperature sensor, partially faulty element, or convection fan issues.
  • Oven won’t turn on: Power supply, tripped circuit breaker, defective control panel, or main board failure.
  • Door problems: Broken hinge, faulty latch, or worn-out gasket leading to heat loss.
  • Self-cleaning function failure: Door latch issue, control board problem, or blown thermal fuse.
  • Strange noises or smells: Banging, buzzing, clicking, or burning smells indicating wiring issues.
  • Temperature control problems: Oven runs too hot or cold due to a faulty thermostat or sensor calibration.

One more we see a lot: an oven that’s off by 25 to 50 degrees even though nothing’s broken. That’s calibration drift, and most control boards let us re-calibrate the offset instead of swapping parts. We work on Whirlpool, GE, Samsung, LG, KitchenAid, Frigidaire, and the rest, and we handle stove repair in San Diego on the same visit when the cooktop’s acting up too.

What does it cost to repair an oven?

Oven repair cost comes down to what part failed and how long it takes to reach it. A bake element on an electric range is one of the cheaper, faster fixes. A control board or gas safety valve runs higher. Here’s what moves the bill:

  • Type of oven: Gas oven repairs can be more involved due to specialized gas fitting knowledge. Electric oven repairs often deal with expensive electronic components.
  • The specific part needed: Simple component replacements, like an element or igniter, are less expensive than complex control board or gas valve repairs.
  • Labor time: More complex diagnostics and repairs require more technician time.
  • Brand and model: Premium brands may have more expensive parts or require specific expertise.
  • Diagnostic fee: Most reputable companies charge a diagnostic fee, often applied towards the total repair cost.

Our tech diagnoses the oven first, then gives you the part-and-labor number before touching a wrench for your oven repair in San Diego. With gas models especially, hire someone licensed. You can check any contractor’s license with the California Contractors State License Board (CSLB) at cslb.ca.gov.

Our guarantee for San Diego oven repairs

Here’s how we work an oven call, gas or electric:

  • Local techs who know these brands: We service homes from La Mesa to Carlsbad and carry the common parts for Whirlpool, GE, Samsung, and LG.
  • Same-day when we can: Most oven calls we book same day or next, since a dead oven can’t wait for the week.
  • Estimate before the wrench: You get the part-and-labor number after diagnosis, before we start. No surprises on the invoice.
  • OEM parts: We fit manufacturer-approved elements, sensors, igniters, and boards, not generic substitutes that fail again in a year.
  • We stand behind the work: We guarantee our labor and the parts we install.

For oven repair in San Diego County, call Repair Pro San Diego and we’ll get your oven holding temperature again.

When to call us

You can swap a visible-broken bake element yourself if you’re comfortable killing the breaker first. But anything touching the gas valve, the supply line, or the control board is a job for a professional. If you smell gas, see scorched wiring, or the igniter glows without lighting, stop and call us. We’ll diagnose it and tell you the fix before we start. Call us at (858) 988-7787 for a same-day estimate.
