Why Your Gas Oven Is Not Heating: 5 Causes and What to Do About It
So you’ve finished mixing your banana bread batter, only to discover your gas oven won’t heat up. Don’t let this spoil your moment—there are troubleshooting steps you can take to identify the issue.
First, a safety note: Before attempting any repairs on the gas oven, switch off the breaker connected to it. Always prioritize safety when dealing with gas appliances; if you’re uncertain, contact Appliance Repair SD.
The Circuit Breaker Tripped
Think of the circuit breaker as the distribution center for your home’s electricity. If you’re experiencing issues, check if the circuit breaker has tripped, which would stop the electrical supply to your gas oven.
If the circuit breaker is functioning correctly and your gas oven still won’t light, the next step is to check the gas supply.
The Oven Isn’t Getting Gas
If your gas stove isn’t lighting, there may be an issue with liquid propane or natural gas supply. If you recently had repairs done to your oven or stove top, the gas valve might still be shut off, and you simply need to open it. The gas valve is behind your oven, either on the wall or the floor. It should indicate if it’s in the “On” position. If it is on but the stove still isn’t heating (or if you’re unsure), call Appliance Repair SD for an inspection.
The Temperature Sensor Needs to Be Repositioned
If your gas oven isn’t heating up to the desired temperature or food isn’t cooking evenly, there could be an issue with the temperature sensor. If the sensor touches the inside wall of the oven, it will give inaccurate readings of the oven’s actual temperature, leading to uneven cooking results.
The solution is to reposition the sensor simply. If it’s not touching the inside wall, use an ohmmeter to check if the sensor functions correctly. If it isn’t, it will need to be replaced by professionals.
The Oven Needs to Be Recalibrated
If your favorite roast chicken recipe calls for 475 degrees for 50 minutes, but your oven takes two hours to cook, your oven temperature may need recalibrating. To check, place an oven thermometer inside and heat the oven to 350 degrees Fahrenheit. If the thermometer’s reading significantly differs from the oven’s setting, there’s an issue.
If the oven temperature is off by 20 degrees or less, you can recalibrate it yourself. Refer to your oven’s owner’s manual for specific instructions, which usually involve holding down the “Bake” button, adjusting the temperature, and pressing “Bake” again to save.
If the oven temperature is off by 30 degrees or more, contact our appliance repair technician. This may indicate a problem with the temperature sensors.
The Igniter Needs to Be Cleaned or Replaced
When you turn on the gas oven, you should hear the igniter clicking until the gas ignites. Once the igniter is hot, the gas valve opens to send gas to the burner. However, the oven may not heat up if there’s an issue with the burner.
Here’s how to troubleshoot:
If the Gas Won’t Ignite
If your stove is clicking but the burners aren’t lighting, there may be an issue with the igniter. Turn off the oven or stop trying to ignite it before too much gas accumulates (if you can smell gas, stop immediately).
Before proceeding, turn off the oven at the circuit breaker to ensure it’s disconnected. Inspect the igniter for any discoloration on the coil, as this can indicate it’s no longer functioning.
Perform a Multimeter Test
Another option is to check the resistance of the igniter using a multimeter. A working igniter typically shows a resistance between 10 and 2500 ohms. If there is no continuity or resistance, the igniter is faulty and needs to be replaced.
Replace the Igniter
If you find that the igniter is not working after checking it, you’ll need to replace it. Replacing the igniter can be straightforward and often done with a circuit tester, a new igniter, and a screwdriver. If you’re uncomfortable doing this alone, contact a us.
