Circuit Braker Jump Off Easily on GE JP350 Cooktop

Hi Danielle, I reviewed the manual for the GE JP350 cook top. Pg. 6 states:

"The UNIT ON indicator light will glow when any surface unit is on."

If the burners are all set fully to the Off position, this lamp should be off. The off position requires that the knob be pressed in to change to Lo, High or any position between (once no longer in the Off position, depressing the knob to change it is not required). If you're able to change the from Off position without pressing the knob, there is an issue with the switch - that may be contributing to the problem.

The cooktop is a 208 / 240 volt appliance. This is the highest voltage in your home. Voltages as low as 50 in the right circumstances can kill, and for this reason repairs must be performed with safety as the first priority. The cooktop sensors have determined that a control is on. If they are indeed off, there is a problem with either the sensor or one (or more) of the controls. You may have luck by locating the circuit breaker or fuse (2 pole 40 amp breaker or (2) 40 amp fuses) and removing power from the cooktop for a minute or two, and then restore power. This would allow the electronics to reset and if a logic problem - it would clear. If there is a hard fault somewhere, the indication would return again.

You should have the cooktop professionally serviced if the indicator fails to extinguish. I hope this helps & good luck!

Hi sounds like you have a busted switch assembly, this is very much fixable the part is around $50, but you would need to remove the top of the stove which requires pulling the unit from the counter, this is slightly more involved, but definitely doable i would also change the knob. A more accurate name would be infinite switch.

One of the heat elements is touching ground. Not worth repairing as you have to replace at least 2, maybe all elements

This is usually the infinite switch has failed. They are easy to check and inexpensive. There is a video at www.appliancehelponline.com/servicemanual.html that will walk you thru testing this. It may be a different model but the testing will be the same. You can also enter your model # for diagrams and illustrations for your specific model. Not all models are available. All parts come with installation instructions.

Did you just clean it? If the swiches under the burner knobs get wet, they cause the electrodes to click. Unplug the unit or turn off the braker for a day. it should dry up and work normal.

TURN OFF CIRCUIT BREAKER. Lift out cooktop, remove all machine screws holding the glass frame. Remove plastic knobs and lift glass top straight up. Make sure rubber gromits are not ripped or torn. Unscrew the small screws on the selector switch and then lift up and tilt over the small aluminum chasis holding the switches to expose the wiring connections. Pull off the wires and pull out the defective switch. Replacre switch, connect wires, re-seat switch chasis, and secure switch with screws. Carefully drop in the glasstop lining up the switch shafts and the rubber grommets. Secure the top with machine screws and drop back in the cutout.

Did you move the breaker fully off before turning it back on? make sure the offending burner is off.

It sounds as though the element shorted out.

You probably have a burnt out element. They almost always short out when they burn out. If it is a coil unit it may be visible. A smooth top unit can't be diagnosed without removing the top glass. Most of the time you can do this yourself. Sometimes when a burner goes it will ruin the switch also.
