An oven that won't heat or heats unevenly is a serious inconvenience — especially in Houston where many households cook daily. The good news is that most oven heating failures have clear, fixable causes. Here's how to diagnose yours.
Electric Ovens: The 3 Most Common Failures
1. Bake or broil element failure The bake element sits on the bottom of the oven cavity; the broil element on the top. Both are resistive heating elements that glow red when working. When they fail, they often visually show a burn mark, blister, or visible break in the coil.
Diagnosis: Set the oven to bake at 350°F and wait 5 minutes. Look for the bottom element glowing red. If it's dark or glowing unevenly, it's the likely culprit. Repair cost: $120–220 parts and labor. Most common oven repair.
2. Control board failure The control board is the oven's brain — it reads the thermostat and controls when elements cycle on and off. When it fails, the oven may not heat at all, heat erratically, or display error codes.
Signs: Display error code, oven works intermittently, buttons not responding. Repair cost: $200–400 parts and labor.
3. Oven temperature sensor The temperature sensor tells the control board how hot the oven actually is. A failed sensor causes the oven to run too hot, too cold, or not start at all.
Signs: Food burns consistently or is consistently undercooked at correct settings, oven displays temperature errors. Repair cost: $100–180 parts and labor.
Gas Ovens: The #1 Failure
Igniter failure Gas oven igniters both light the gas and open the gas safety valve. The igniter must reach a precise current threshold before the valve opens — as igniters age, they weaken and take longer to reach that threshold, or fail entirely.
Signs: Oven takes 5+ minutes to preheat, clicking sound with no ignition, oven doesn't heat at all. Repair cost: $130–220 parts and labor. Very common repair.
Note: If you smell gas but the oven isn't lighting, turn it off, ventilate the area, and call a technician immediately. Don't attempt to light manually.
Houston-Specific: Power Fluctuations
Houston's electrical grid (served by ERCOT, separate from the national grid) experiences power fluctuations during summer peak demand and during severe weather events. Voltage spikes can fry control boards and sensors. Consider a whole-house surge protector if your appliances have experienced unexplained control board failures.

Gas Oven Igniter Failure in Houston Homes
Houston homes with natural gas ovens most often experience no-heat failures due to a weak or failed igniter, not a gas supply problem. The igniter draws current to glow and open the gas valve; when the igniter weakens with age, it glows but never gets hot enough to trigger the valve. Signs include extremely long preheat times of 15 minutes or more, or an oven that occasionally fails to light the burner. Igniter replacement in Houston costs $130-$200 and is a same-day repair in most cases.
Scheduling Houston Oven Repair
Oven repair in Houston is best handled by a licensed appliance technician for safety reasons — gas connections require qualified handling, and electric ovens involve 240V wiring. Same-day oven repair is available throughout Houston and Harris County for all major brands. When you call, describe exactly what the oven does and does not do: whether the broiler works, whether the oven reaches partial temperature, and whether any error codes are displayed. This information helps the technician identify the likely failed component and arrive prepared to complete the repair in a single visit.
