that isn't a good model number,how old is this oven?if it's over 15 years you can't get parts for it most likely,when you find the model number off of the oven go here and see if you can still get parts for it.

Hi Amanda, you don't say where you are? Maybe worth contacting these people with the Oven model number.

What type (dishwasher, washing machine ect.) Brand and if possible model number. It will allow for a more helpful answer.

The model number/serial number plate for most Sears Ranges is behind the oven door, in one of the four corners of the opening.

Do you know about how this unit is? I tried the model number you posted on two different websites and they came up with nothing. Either it is too old or you do not have the right model number. Sorry.

Good Morning Friend,

I understand that your Frigidaire electric oven, model# es 200/300, will not shut off. I also see that it gets very hot, way past the set temperature. First, make sure you have not put it into the self-cleaning cycle. If it is not in the self-cleaning cycle, I suggest resetting your appliance, by shutting the power off at your home's circuit breaker, for 3-5 minutes. Once power is restored, you will need to set the clock before starting any cycle. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your air conditioner status has changed successfully. Hope this is helpful.

-Best Regards-

I saw your question while searching for something else. Since I have the paper manuals that came with my range (same model), I can give you the part numbers you need. Google for the the parts. Don't be dismayed if it shows "Electrolux", the manuals displayed are what you want.
Manual for various oven models: Kenmore 318200431 0403
Electronic oven control: Kenmore 318200193 0110
Good luck!

Don't replace anythingf, try this! The insulation in the ribbon cable is poor. The conductors in the cable are crossed. The ribbon cable is actually two ribbons pressed together, and the conductors between the two cables are shorting or becomming crossed. Lift the two cables apart, place a piece of paper between them, fold the edges of the paper over the cable so that it does not slip out, and make sure to shove it all the way down to where it will meet the plastic display panel housing. There, problem solved.
