I have a 790.75403500 Kenmore Elite gas range and the oven will not turn on any more. It has been taking a long time to preheat and I have smelled gas sometimes, but not always. The burners work fine,

There are several potential causes for a gas range being slow to preheat. Here are some troubleshooting steps you can try:

1. Check the igniter: While the igniter may be coming on, it may not be getting hot enough to ignite the gas. Make sure the igniter is clean and free from any debris or corrosion. If it is dirty, gently clean it with a soft cloth. If the igniter is damaged or not getting hot enough, it may need to be replaced.
2. Check the gas supply: Make sure that the gas supply is turned on and that the gas pressure is sufficient. If the gas pressure is too low, the oven may take longer to preheat.
3. Check the oven temperature sensor: A faulty temperature sensor can cause the oven to take longer to preheat. Use a multimeter to test the sensor for continuity. If it is not working properly, it may need to be replaced.
4. Check the oven door seal: A faulty oven door seal can cause heat to escape, making it difficult for the oven to reach the desired temperature. Inspect the seal for any cracks or gaps, and replace it if necessary.
5. Check the oven igniter safety valve: The igniter safety valve is responsible for regulating the flow of gas to the oven. If it is faulty, it may be restricting the flow of gas, causing the oven to take longer to preheat.

If you are uncomfortable performing any of these troubleshooting steps yourself, it is best to contact a qualified appliance repair technician for assistance.

Don't use this oven, turn off the gas and call a service techinican

Check the burner, most likely the burners gos holes are clogged with ash, etc. Clean with a small pin, just try not to enlarge them if possible.

It gas not electric. There is NO hidden element. It a bad sensor.

Always preheat your oven and let it cycle at least 2 times. Your unit may show 350 but the manufactures know that it is not 350. When it registers preheated, it really means that it is at an acceptable temperature to start cooking. If you think that it may not be calibrated correctly, your owner's manual will have instructions on how to recalibrate your oven. You will be able to raise or lower the temperature by + 25 degrees or - 25 degrees. As far as the gas smell, you will from time to time smell a gas smell with a gas oven especially if you are right at it when it ignites. If you are smelling gas when it is not in use then you should be extremely concerned.

Chances are the oven ignitor will need to be replaced.  Look and see if it glows.  If it does then it is weak and not opening the gas valve to lite.  Let me know what you find.

Should be able to remove the bottom drawer and unplug the ignitor from below.  Or you can cut the wires on the old ignitor and splice the new one in using ceramic
