One oven lights but will not increase temp to the required setting

I'd recommend buying an oven temp dial to stick in your oven to verify the actual temp. Then you can turn on the oven using a lower setting and write down the temp for the setting. Then as you slowly adjust the setting higher and higher, note each temp. If it doesn't show a consistent increase of temp for each setting, you may need it calibrated or replaced. Good luck!

I'm guessing that you want your oven at 100 degrees for drying some food/herbs, or culturing homemade yoghurt. I do all of those, so know the temp range required; 95-110. Most ovens can't be set as low as 100, but the cool thing about a gas range is that the pilot light keeps the interior temperature close to that, and if you keep the oven interior light on, that helps. Get an oven thermometer, costs under $10, test oven temp. If your oven doesn't do it you can get a pizza stone or even a few bricks, preheat the oven to warm the stone/bricks on the bottom rack, turn oven off. Then put in your product of choice on top rack. Leave yoghurt in for 8 hours, leafy herbs (sage, thyme, oregano, etc) for 12 or more hours. If doing yoghurt, don't open door, consistent temp is important. If doing herbs, crack the oven door open slightly with a wooden spoon to allow moisture to escape, critical to drying. I hope this helps.

Unplug the range open the control panel to access the electronic oven control. Unplug the wires and wait 5 minutes. Replace all wires on the control and turn the power back on.
If this does not reset your oven control it must be replaced.
Your ERC(clock) is bad and must be replaced.

Thermostat may need adjusting OR air may be entering the oven causing the problem

change temp control

You will need to replace the temp probe Call704-891-6557 we'll tell you how to do it safely.

I HAVE A 2 MONTH OLD GAS RANGE AND IT APPEARS ED-F3 AND THE OVEN DOOR IS LOCKED HOW DO I GET IT TO UNLOCK

Press the bake key.
Adjust temperature to 550 degress.
Press the bake key again and hold it for 3 seconds.
The temperature +/- should appear.
You can then adjust temp +/- 35 degrees.

it could be your oven control unit

Possibly bake element is bad or control is bad.
