Oven Not Heating? 7 Common Causes and How to Fix Them
If your oven is not heating, you are not alone — it is one of the most common appliance problems we see in Frederick, MD homes. The good news: several causes are simple to check yourself in a few minutes. The rest need a technician, and knowing which is which can save you a service call — or stop a small problem from becoming an expensive one.
Before you start: turn the oven off and let it cool completely. If you smell gas at any point, leave the house and call your gas company first.
1. A Failed Igniter (Gas Ovens)
On gas ovens, the igniter is the part that glows and lights the burner. Over time it weakens: it may still glow orange but no longer get hot enough to open the gas valve, so the oven never heats. A weak igniter is the single most common cause of a gas oven not heating. Igniters are not repairable — they are replaced. If your oven takes much longer than it used to to preheat, a dying igniter is the likely reason.
2. A Burned-Out Bake Element (Electric Ovens)
Electric ovens heat with a bake element at the bottom of the oven cavity. When it fails, it often shows visible damage — blisters, cracks, or a bright spot that glows unevenly. Turn the oven to Bake: the element should glow red evenly along its whole length. If part of it stays dark, the element has burned out and needs replacement.
3. A Tripped Breaker or Power Issue
Electric ovens run on 240 volts, delivered through two breakers. If one trips, the oven can look alive — lights on, display working — but the elements only get half power and never reach temperature. Check your breaker panel for a tripped breaker and reset it. If it trips again right away, stop and call a technician; that usually means a short in the oven.
4. A Faulty Temperature Sensor
The temperature sensor tells the control board how hot the oven is. When it drifts out of calibration or fails, the oven may shut off early, never reach the set temperature, or heat unevenly. Symptoms include cakes that bake on one side only and preheat times that keep getting longer. Sensors are tested with a multimeter and replaced if their resistance is out of range.
5. A Worn Broil Element Being Used as a Crutch
Some ovens try to compensate for a dead bake element by leaning on the broil element during preheat. Food may cook — slowly and unevenly — which makes the problem easy to miss for weeks. If preheating takes twice as long as it used to but the oven eventually gets warm, the bake element is the first thing to check.
6. A Failed Control Board or Relay
If the elements and igniter test fine, the problem may be the electronic control board or a relay that sends power to them. Boards can fail after a power surge — common after summer storms in Frederick County. Board problems usually need a professional diagnosis, because guessing wrong here gets expensive fast.
7. A Gas Supply Problem (Gas Ovens)
If none of the burners on your stovetop light either, the issue is gas supply, not the oven: check that the gas shutoff valve behind the range is fully open. If the stovetop works but the oven does not, go back to the igniter — cause #1.
When to Call a Professional
Call a technician if: you smell gas, the breaker keeps tripping, the oven heats but the temperature is far off, or you have checked the basics above and the oven still will not heat. Working inside an oven means 240-volt power or gas lines — both are worth respecting.

FAQs
Why is my oven not heating but the stove works? On gas models, the stovetop burners and the oven igniter are separate systems — a weak igniter stops the oven while the burners still light. On electric models, the bake element can burn out while the stovetop elements keep working.
How much does it cost to fix an oven that is not heating? It depends on the part: an igniter or bake element is usually one of the more affordable repairs, while a control board costs more. Our full breakdown is in our appliance repair cost guide.
Can I replace an oven igniter myself? It is one of the simpler parts to swap, but it involves gas connections and fragile ceramic parts. If you are not comfortable working around gas, this is a good one to hand to a technician.
