Question about Whirlpool GS470LEM Gas Kitchen Range
My LG range was having problems where the stovetop burner and/or oven would just shut off. In the case of the oven, sometimes it would fail during the preheat stage, while other times it would shut off after preheating. The control panels were replaced on the range twice. LG finally decided to replace the entire unit. While the stovetop burners now seem to work without problem, I'm still having trouble with the oven shutting off. I thought that maybe there's a problem with the electrical wiring, but I can turn all 5 stovetop burners on at high power at the same time, and they work fine, so it doesn't seem like a house wiring problem.
SOURCE: unable to preheat
You need to replace the temp. sensor. It's not reading correctly. These occasionally go when you use the self clean as the range gets up as high as 900 degrees. Replace it and it will solve the problem

When you say "Just shut off" do you mean the circuit breakers would trip, or fuses would blow? If so, I would have an electrician check that the circuit is properly fused/breakered and wire sized for the amount of power required by the oven. If the installation directions say it needs a 50 amp service, it better be a 50 amp service.
If shutting off is just something within the oven, then get LG back out again, and let us know of what they say is wrong.

Here are two instances of when food "bakes poorly:"
You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.
If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.
If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective.
Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details.
Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat.
If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.
