When I put the power on the oven heats up and the elements won't go out. It seems like the system is stuck inself cleaning mode. How can I clear this? The model # is 38HW 6JTV.

Check for incoming power; you may need to change the heater element.

If the elements are not heating ,there are some explanations
the thermostat for the oven is not working ( most probable)
the power to the elements is not switching on--- oven switch or a fuse is blown in the system or power board out side
won't be the power board if the rest of the stove is working
have an electrician check out the system

The upper element is for broiling and should not come on until you tell it broil. If it is coming on as soon as you turn on the breaker then it sounds like the printed circuit control board is bad. There is a relay on the board that engages when you program in the broiler. The relay can be hard to find and may not be removable. My broiler would come on when I programmed in the bake mode, go into runaway heat, put up a F10 code, and shut off. I could not clear it until I programmed in the clean mode for 2 hours. Now it works great.

the upper element only comes on when you broil or clean with selfcleaner. the bottom comes on when you are baking, it sounds like your bottom element is bad.

Contact a professional to have the unit diagnosed for repairs. Sounds like the heating elements are either faulty or the main control board won't allow the unit to heat up correctly.

Buy a new stove element. If you open the stove look in the back. It should be black. It might have a crack or be clearly broken. This is a cheap fix. If you want to be sure that it is working at the connection unplug the element and pull it out. Put a volt meter into the prongs. Turn stove on and see if its putting out voltage.

sounds like when you put it on bake only the broil element is coming on,when in bake both elements come on,set it to bake,does the bake element glow orange when it heats up,if not the element could be bad and the heat is coming from the broil element or you could be only getting 120 volts to the element,so start it and see if the element glows orange or after like 5 minutes touch the element with a wet paper towel and see if it's even getting hot at all,if not make sure you unplug it or flip the breaker before you go to remove the element,there's 240 volts going to it and power is there all the time,i've seen people try to take it out with the power on thinking that the oven isn't on and POP not only is the element bad but they took out the relay in the clock assy. to by doing that.if you want to write back and let me know what you find i'd be happy to help you if you need more help.

Thanks for choosing FixYa and welcome. you have a electric oven or a gas oven that won't heat or doesn't heat properly, here are some things you will need to check. The most likely cause of a oven not heating correctly is a defective heating element. You have two types of heating elements in your oven. The bottom element(s) are the baking elements. The element(s) on the top are the broil elements. If you don't see the bright red glow from the element, chances are they are not working or not working correctly. If a heating element is bad, you need to replace the entire element. If your oven is warm and not correctly hot, one of the elements may be bad. In most ovens, when you preheat, both elements are used. This would make the oven to appear like it is working correctly but it is not. If the elements are not working, they might not be getting power. Test the wires to the elements with a voltage meter to make sure they are getting power before you decide to change them out. Many electrical ovens have a sensor that monitors the oven temperture. Ovens that have this sensor usually contain a digital display on the oven. The sensor could be defective. Those without the sensor use the basic mechanical system to control the oven temperature. You also want to check the thermostat sensing bulb. Make sure the bulb is good and has not come loose. Now, if you have a gas range oven that doesn't heat properly, first, you want to check your bake igniter. It may have burned out or it could be not working properly. It will be located near your burner. It is also possible that you are not getting gas to the burner. If so, it may be the gas safety valve or the igniter. You need to check your selector switch and thermostat as well. They may be defective. Always make sure you test the parts for power with a voltage meter of some type before you decide to change the part. If you have a part that appears to not be working, it may not be getting power because of a bad wire or broken connection.

I would suggest that you check the oven element, it sounds as though it is faulty to me.
