Wondering why your oven won’t heat up? If your oven stopped working or isn’t reaching the desired temperature, the most common culprits are a faulty heating element (electric), a defective igniter (gas), a damaged temperature sensor, or an electrical issue such as a tripped circuit breaker. Most of these can be identified with a few safe visual checks. However, some require a professional repair technician.
This guide covers both gas and electric ovens, explains what to check first, and when the repair is best left to a professional. If you’re an Arizona homeowner dealing with oven issues, here’s where to start.
Start With Initial Safety Checks
Before opening panels or inspecting components, run through these basic checks. They take less than two minutes and resolve the problem more often than you’d expect:
- Check the Power Supply – Make sure your electric oven is fully plugged into the wall outlet. A slightly loose connection can cut power entirely.
- Inspect the Circuit Breaker – Electric ovens draw significant power. Head to your breaker panel and look for a tripped switch. Reset it by flipping it fully off, then back on. If it trips again immediately, stop and call a technician.
- Check the Oven Door Seal – A damaged or debris-clogged door gasket lets heat escape, causing the oven to struggle reaching the desired temperature. Run your finger along the seal and look for tears or buildup.
- Confirm the Gas Valve Is Open – For gas ovens, make sure the shutoff valve behind the unit is in the fully open (parallel to the pipe) position.
- Check for Error Codes – Many modern ovens display fault codes on the control panel. Look up your model’s code in the owner’s manual, and it can point you directly to the issue.
What Causes an Electric Oven Burner to Not Work?
Electric ovens rely on two main heating elements: the bake element at the bottom and the broil element at the top. When either fails, your electric oven burner stops working, and heat distribution becomes uneven or disappears entirely. A failed heating element is usually easy to spot. It won’t glow red or orange when the oven is on, and you may notice visible damage like blistering, cracks, or burn marks. Another telltale sign is food that cooks unevenly or not at all.
A damaged element is a relatively common repair, but because it involves high-voltage components, replacement is safer when handled by a licensed appliance technician. Attempting to replace it yourself without disconnecting power at the breaker first can be dangerous.
Is a Faulty Gas Oven Igniter a Common Reason My Oven Isn’t Heating Up?
In a gas oven, the igniter draws an electrical current to heat up and open the gas valve, allowing fuel to flow and ignite. When the igniter weakens or fails, the gas valve may not open, and the oven doesn’t heat up at all. Signs of a faulty igniter include:
- The igniter glows but takes more than 90 seconds to light
- The oven doesn’t light at all
- You hear a soft clicking but see no flame
What Does It Mean When an Oven Is Making a Clicking Noise When Preheating?
An oven making a clicking noise when preheating is completely normal and often misread as a sign of a problem. Gas ovens use a spark igniter that clicks repeatedly until the burner lights. You’ll hear several rapid clicks at startup, which stop once the flame ignites. This is expected behavior.
However, clicking that continues long after the oven should’ve lit is a problem. Persistent clicking after ignition attempts often points to a dirty or misaligned igniter, a clogged burner port, or a failing spark module. Turn off the oven and ventilate the kitchen if you smell gas and can’t identify the source. Contact a technician immediately.
How Does a Faulty Temperature Sensor Cause Oven Heating Problems?
The temperature sensor, sometimes called an oven thermistor, monitors the internal temperature and tells the control board when to cycle the heating on or off. A damaged or misaligned sensor causes the oven to heat incorrectly, even when it appears to be working.
A faulty temperature sensor can cause food to be consistently over- or undercooked and may cause the oven to run hotter or cooler than the temperature you’ve set. You may also notice the oven cycling on and off erratically.
The sensor is a slender probe, usually located at the back interior wall of the oven. You can visually inspect it to see if it’s touching the oven wall (it shouldn’t be) or shows signs of damage. Testing it properly requires a multimeter, and replacement should be handled by a technician on most models.
When Should You Call a Professional?
Some oven issues are safe to investigate at home. Others are not. Call a licensed appliance repair technician if:
- You suspect a gas leak.
- The circuit breaker trips repeatedly after being reset.
- You see burn marks, melted wiring, or smell burning plastic.
- The oven isn’t heating up or displays recurring error codes after a reset.
- The control board appears damaged, or the oven is entirely unresponsive.
Stop Guessing and Let the Experts Fix Your Oven
Most oven heating problems trace back to a handful of components, such as a worn igniter, a damaged heating element, a faulty temperature sensor, or an electrical fault. Safe visual checks can quickly narrow down the cause, and many issues are straightforward for a qualified technician to resolve.
