Oven problems, light stays on, will not preheat or heat

SOURCE: Preheat taking long time

If your oven has the hidden bake element then it is probably working properly. A standard oven with an exposed bake element will usually take about 12-15 minutes to preheat. The hidden element models take a little longer but they usually heat a little more evenly.
Post back if you have any more questions.

Need to check and see if you are getting 220 volts to the element or if the element is showing resistance with an ohm meter. Any resistance means it is ok. If you are not getting voltage to the elements and resistance is ok then the control board is bad. Note: Always check outlet for proper voltage first! Never know when a breaker has gone bad. Should have 220 volts from line 1 to line 2 and 110 volts from line 1 or line 2 to ground.

I'm afraid you may have a blown Electronic Oven Control (EOC) board. The EOC controls all the functions of the oven. The surface elements are controlled by individual infinite switches behind each control knob.. That's why the surface elements all work, but the oven does not. A replacement EOC can be purchased on line at searspartsdirect.com. Just type in your COMPLETE model number and you will find it under the "Control Panel Parts" heading as item number 12. There are several listed, based upon the color you need (White, Biscuit, and Black). This is a very simple repair that any do-it-yourselfer can accomplish if you wish to perform this on your own. All you have to do is UNPLUG the appliance and remove the back panel of the console to access.

Before assuming the EOC is defective, however, inspect the board to see if it has a fuse on it. I do not have a wiring diagram to confirm. Some of these boards do have fuses and that's all that it may take to repair it. However, if the board shows signs of burned components, replace it. NOTE: Check for any loose connectors to the board as well.

I hope you find this information helpful. Let me know if you have questions and/or require additional assistance.

The first thing you will need to do is to verify that you have 230 volts at the outlet. Chances are pretty good that the unit popped one of the double pole breakers. Check the breaker and reset it if you find that you only have 120 volts at the outlet. If after finding that you have only 120 volts and you've reset the breaker then the problem would lie with the breaker needing replacement. If however you have full 230 volts available at the outlet then additional troubleshooting would be needed. Hope this helps... Bill
