Why the display can work while the oven stays cold
Most electric ranges use a 120/240-volt supply. The clock, lights, and electronic control can operate from one 120-volt leg even when the second leg is missing. That is why a bright display does not prove the oven has the full voltage needed to energize a bake or broil element.
A similar symptom occurs when the control receives both supply legs but does not send voltage through a bake relay, thermal cutoff, selector switch, or damaged harness.
Safe checks before scheduling service
- Cancel the cycle and verify the oven is not in demo, Sabbath, delay-start, or control-lock mode.
- Reset the double-pole range breaker by moving it fully off, waiting one minute, and switching it fully on.
- Test bake and broil separately. Note whether either element warms and whether the control clicks.
- Stop immediately if you smell burning insulation, see arcing, or the breaker trips again.
Do not remove the rear cover or measure the terminal block unless you are trained for live 240-volt diagnosis. An oven can retain a working 120-volt control circuit while dangerous line voltage is present elsewhere.
Understanding “120V in, 0V out”
Technicians use the wiring diagram and model-specific service sheet to determine which relay should close during bake. They verify both incoming line legs, then measure the control output under a heat command.
If the board has the required input but sends zero volts to the element circuit, a failed relay or burned board connection is likely. If the board sends voltage but the element stays cold, the element, thermal protection device, or wiring may be open.
Common component-level causes
- A burned bake relay on the electronic oven control
- An open bake element or concealed heating element
- A failed high-limit thermostat or thermal fuse
- Heat-damaged wiring at the element or terminal block
- One missing 120-volt supply leg from the breaker, receptacle, or cord
For an overheating fault rather than a no-heat condition, see the GE oven F2 error guide.
When to call a technician
Schedule professional diagnosis when the breaker reset does not restore heat, when both bake and broil are cold, or when electrical damage is visible. A technician can distinguish a supply problem from an element, relay, or safety-device failure before replacing parts.

Frequently Asked Questions About General Oven
Why does my oven display turn on but the oven won't heat up?
Electric ovens require 240 volts of power. The display and clock only need 120 volts to function. If one leg of your home's dual-pole circuit breaker trips, the oven display will light up, but the heating elements won't receive enough voltage to heat up.
How do I know if my oven's bake element is burned out?
Visually inspect the element for physical breaks, blistering, or spots. If you have a multimeter, you can test the element for continuity. If the element lacks continuity or shows physical damage, it must be replaced with an OEM part by a licensed technician.
