Whether you cook on a gas or electric oven, mechanical issues are inevitable over time. Understanding the common problems specific to your oven type — and what repairs typically cost — helps you make informed decisions when something goes wrong.
Here is a practical breakdown of gas versus electric oven problems, repair costs, and when to call for professional service in the Valley of the Sun.
Common Gas Oven Problems
Igniter Failure
The igniter is the most commonly replaced part on a gas oven. It glows red-hot to ignite the gas burner. Over time, igniters weaken and cannot reach the temperature needed to open the gas safety valve. You will notice the oven taking longer to preheat, or it may not heat at all.
Typical repair cost: $150 to $250 including parts and labor.
Gas Valve Problems
If the oven igniter is working but the burner still will not light, the gas safety valve may be faulty. This valve opens when the igniter reaches the correct temperature. A failed valve prevents gas from reaching the burner.
Typical repair cost: $200 to $350.
Thermostat and Temperature Irregularities
Gas ovens rely on a thermostat to cycle the burner on and off to maintain the set temperature. A faulty thermostat can cause uneven cooking, the oven running too hot, or the oven not reaching temperature at all.
Typical repair cost: $150 to $300.
Burner Issues
Stovetop burners on gas ranges can develop clogged ports, faulty spark igniters, or worn burner valves. These issues are usually straightforward repairs.
Typical repair cost: $100 to $200 per burner.
Common Electric Oven Problems
Bake or Broil Element Failure
Electric ovens use heating elements for baking (bottom) and broiling (top). When an element burns out, you will usually see a visible break or blister in the coil. The oven may heat unevenly or not heat at all on that setting.
Typical repair cost: $150 to $250.
Control Board Malfunction
Modern electric ovens and ranges use electronic control boards to manage temperature, timers, and cooking modes. When the control board fails, the oven may display error codes, not respond to input, or behave erratically. In Arizona, high ambient temperatures can contribute to control board failures, especially if your kitchen runs hot.
Typical repair cost: $200 to $500, depending on the model.
Temperature Sensor Problems
The temperature sensor monitors the oven's internal temperature and sends data to the control board. A faulty sensor can cause the oven to undercook or overcook food. You can sometimes test the sensor's resistance with a multimeter, but replacement is a job for a technician.
Typical repair cost: $100 to $200.
Self-Cleaning Cycle Issues
The self-cleaning cycle heats the oven to extremely high temperatures. This intense heat can blow fuses, damage door lock mechanisms, or crack weakened heating elements. If your oven will not unlock after a self-cleaning cycle, do not force the door — call for service.
Typical repair cost: $100 to $300.
Gas vs Electric: Which Costs More to Repair?
On average, gas oven repairs cost slightly more due to the complexity of gas components and the safety requirements involved. However, electric oven control board replacements can be among the most expensive individual repairs for either type.
Both gas and electric ovens generally last 13 to 20 years with proper maintenance, so the difference in repair costs over the life of the appliance is usually small.
Safety Considerations
Gas oven repairs should always be performed by a qualified technician. Improper gas work can lead to gas leaks, carbon monoxide exposure, and fire hazards. If you smell gas, leave your home immediately and call your gas utility before calling for repair.
