If nothing is heating -- not any of the burners, nor the baking or broiling elements -- it's likely a lack of power to the unit is causing the problem. Check to make sure the stove is plugged in and that the circuit breaker has not been triggered. If it is plugged in and the circuit is on, it could be a problem in the wiring. This issue could be in the wiring in the wall or in the back of the unit. Either problem should be diagnosed and repaired by a professional.
The tube that runs along the bottom of your oven is the baking element. When you set the oven to bake, it heats up and glows red. If, after you turn the thermostat on, the baking element does not glow red, it probably has burned out. If this is the case, it needs to be replaced.
The tubes that line the top of your oven are the broiling element. They are very similar to the baking element and, like the baking element, glow red when they heat up. Set your oven to broil, and see if they heat up and glow red. If not, they are broken and need to be replaced.
Your GE Profile stove has a thermostat sensor that monitors the temperature of the oven. The temperature is set by use of a digital display. If the display has an electrical wiring problem, it will not trigger the heating elements to heat the stove. If the display works correctly but the sensor does not, it also will cause heating problems. Either problem should be diagnosed and repaired by a professional.
Gas, electric and induction burners do not last indefinitely. The first two have heating elements that can burn out. If only one of your gas or electric burners is not working, it probably needs to be replaced. Induction cooktops use magnetic fields to transfer heat directly to pots and pans -- which is why they are cool to the touch. The fields are generated with the help of electricity, however, which means if the induction cooktop is not working it is probably a wiring problem that needs to be diagnosed and repaired by a professional.
