I need a diagnosis or the proper test to diagnos the problem with a gas oven.
The problem is that if I light the oven and turn it to the lowest setting (250 degrees), an hour later the tempurature maxes out at (500 degrees). If I turn the temp knob up to (350 degrees) the temperature remains at (500 degrees). The same at (450 degrees)
What is your best guess. Thank you.

Hello: Rightoo
Whenever an ovens thermostat fails to control the temperature totally, as in the oven your describing here or the thermostat cannot remain no higher or lower then 50 degrees from the set temp. the thermostat is most likely defective.
About the only check that you can make is to be sure the temp sensor inside the baking compartment is secured in the two clips that hold it in place and that it is NOT physically touching any part of the oven directly, except for the holding clips.
If all the above applies and is correct, replacement of the thermostat is the ONLY solution...period.
Below is an article I recently posted on the topic:
When an oven fails to maintain the desired set temperature, before any parts are replaced, I suggest you have the thermostat checked for calibration. If the thermostat needs a recalibration, this is NOT a do-it-yourself task.
Special tools, training, practice, proceedure and experience are needed along with the proper technique and adjustments made in the correct sequence in order to successully accomplish the task.
Done incorrectly, as a do-it-yourself task, can ruin a good thermostat that otherwise only needed an adjustment...:(
I highly suggest you either contact the gas utility company and inquire if they perform this service. If they do not provide this service, contact the local appliance service dealer listed in the phone book.
If a thermostat fails to control oven temperature, burns food items you attempt to prepare, bakes much too quickly or the temperature soars upwards uncontrolled, chances are likely the thermostat will needed to be replaced.
Oven thermostats are a non repairable part. When determined to be defective, there isn't any other option except to replace the entire part.
FYI's:
Any oven thermostat that is more then 50 degrees out of temperature adjustment when the temperature is verified by a trained service person using either an electronic digital readout meter or liquid filled oven thermometer, the thermostat is considered to be defective.
Thermostats can be a do-it-yourself project. Care most be used during the installation process. Most importantly, handle the capillary extension tube sensor carefully. There cannot be any kinks or sharp bends in that thin copper/bronze/brass metal tubing.
Once the new thermostat is installed exactly as the prior one was, be sure to install the sensor element, in the oven compartment, into the two holding/securing clips.
