Oven lights when cold but not when hot

Do you have a flame sensor ? As it sounds like the flame sensor is not clean . Or its cracked and not sending a signal back to the spark module . I would also check the connetions are clean and tight .

Rebecca Yount, we're sorry to learn that your Oven will not ignite. We recommend service due to we aren't certified Technicians and wouldn't be able to advise you on how to relight the pilot light on your Oven.

If this is the design that the oven will click to light they generally will preheat but shut down once they go to standard bake. The oven will try three times to relight but then shuts down and will not try to light again until you reset the oven. If this is the case the oven burner itself is usually the problem. the burner comes with the electrode.

What is the model number of the unit?

What is the complete model number?

Locate in the bottom of the oven is a cover you will need to lift this cover and re-light the pilot, this will allow you to use the oven.

on the gas valve there is an adj. for the pilot size, maybe too small , would try increasing the pilot and see what happens.also the thermocouple might be on the way out ,you might want to replace that and try oper. go with thermocouple first, then try pilot size dont forget to vote tks. monomoy

Relighting Your Furnace's Pilot Light
- Turn off the gas at the main valve at your utility box - Wait five to ten minutes for gas fumes to waft away - Get a long match—yes, a fireplace match, not a standard match - Set the gas valve on your furnace to "pilot" - Press the red button as you hold the match to the pilot valve - Keep pressing the red button for 30-60 seconds so the pilot can heat the thermocouple. Release the button and see if the pilot remains lit - If pilot goes out, wait five to ten minutes and repeat the process - Once the pilot stays lit, turn the main gas valve back on - If the pilot light continues to go out, call a technician, who may need to adjust or replace your thermocouple or adjust your pilot

Most ovens, unless they have an electric igniter (does it go tick tick tick when plugged in and turned on? If so, it has an electic ignition.) have a pilot light. In order to keep gas from flowing out, and to prevent a possible explosion when the pilot light has gotten put out, they have an electric thermocouple on them that shuts off the gas when it gets cold. Plug the cord back in, and relight your pilot light by holding the lighter (I recommend a fireplace match or bbq lighter, not a cigarette lighter to prevent singed knuckle hairs!) over the thermocouple for a couple of minutes.

I have the same problem. I noticed that the oven gets to the selected temp ok. Then when the pilot attempts to RELIGHT, it gets the error F3. Did you get a solution? After other posts, I will see if the temp sensor is around 1100 ohm as suggested by others. Ken
