Quick help
| What you see | Safe next step | When to request service |
|---|---|---|
| Oven will not heat | Check that a cooking mode is selected and whether other household circuits have power. Read the matching GE manual before any control sequence. | If it still fails, trips a breaker or has a burning odor, stop and call service. |
| An unfamiliar oven display | Write down the exact characters, including any letter and number, then compare them with the official owner’s manual. | If the message returns after any documented user-level step, contact GE. |
| Surface element seems unusual | Turn the surface control off, let it cool, and identify the element type from this model’s manual before cleaning. | Stop for cracking, sparking, exposed wires or repeated inability to heat. |
