Direct answer: When a Miele oven broiler is not working, the most common causes are the wrong cooking mode, a broil element that is not heating evenly, or a temperature-sensing problem that keeps the oven from driving the broiler correctly.
Most likely: Start by confirming you are in an actual broil setting, give it a few minutes to respond, and look for visible glow or heat from the upper broil element. If bake still works but broil stays cold, the upper oven heating element is the strongest suspect.
Broil problems can look bigger than they are. A lot of homeowners expect instant red heat, but some ovens cycle the broiler and take a minute to show it. Reality check: broil is usually an upper-heat problem, not an all-oven problem. Common wrong move: replacing parts because the element does not glow bright red in the first few seconds.
Don’t start with: Do not start by ordering a control board. On ovens, setup issues and failed heating elements are far more common than a bad control.
You select broil, wait several minutes, and the upper area stays cool with no real heat hitting the food.
Start here: Check settings, door position, and whether the upper broil element shows any signs of heating or damage.
Food dries out or barely browns, and the top heat feels weak compared with normal broiling.
Start here: Look for a partially failed broil element or a sensor issue causing short cycling.
The top element may glow briefly, then shut off long before the oven cavity is hot enough for broiling.
Start here: Watch for normal cycling versus a sensor or control problem that cuts the element too early.
The oven is slow to heat, uneven, or not reaching temperature in more than one cooking mode.
Start here: Treat this as a broader oven heating problem and check power supply, sensor behavior, and error indications before blaming the broiler alone.
Some broil complaints come down to the oven being in a different mode, a low broil setting, or not being given enough preheat time to show strong top heat.
Quick check: Cancel the cycle, select broil again, choose the intended broil level, and wait 3 to 5 minutes with the oven empty while you feel for rising top heat from a safe distance.
If bake still works but the top never gets properly hot, the upper oven heating element is the most common failed part on an electric broil complaint.
Quick check: Look for blistering, cracks, burned spots, or one section of the upper element staying dark while another section heats.
A sensor that reads too hot can make the oven cut the broiler early or refuse to drive it long enough for real broiling.
Quick check: If both bake and broil seem weak or short-cycle, and there is no obvious element damage, the oven sensor moves up the list.
If the broil setting is selected correctly, the element tests bad visually or electrically, and wiring is intact, the control may not be sending power to the broil circuit.
Quick check: Suspect this only after simpler checks, especially if the display acts oddly, cycles are inconsistent, or the broil element never gets voltage despite a good element.
A surprising number of broil calls are really setup problems or impatience with normal warm-up and cycling.
Next move: If strong top heat returns, the issue was likely mode selection, timing, or an interrupted cycle rather than a failed part. If the top stays cold or only gets faintly warm, move on to a visual check of the upper element.
What to conclude: This separates a simple operating issue from a real heating failure.
A damaged broil element often tells on itself before you ever touch a meter.
Next move: If you find visible damage, you have a strong diagnosis and can plan on replacing the oven broil element. If the element looks intact, keep going. Elements can fail without dramatic visible damage.
What to conclude: Visible damage on the upper element is one of the clearest signs that the broiler itself has failed.
If bake is also weak, the fix may not be the broil element at all.
Next move: If bake works normally and only broil fails, the upper oven heating element remains the leading suspect. If both modes are weak or erratic, the oven temperature sensor becomes more likely, and control trouble moves up only after that is checked.
Once the simple checks point to a part, a basic continuity check helps confirm it before you buy.
Next move: If the broil element is open, replace the oven broil element. If the sensor reading is clearly wrong and the heating problem affects more than broil, replace the oven temperature sensor. If the element and sensor both check out and wiring looks sound, stop short of guesswork and treat the oven control as a pro-level diagnosis point.
By this point you should either have a supported part failure or a clean reason to stop before expensive guesswork.
A good result: If the top heat comes back strong and food browns normally, the repair is complete.
If not: If the same symptom remains after a confirmed part replacement, the remaining likely causes are damaged wiring or an oven control problem that needs deeper testing.
What to conclude: You either finish with a solid part replacement or avoid wasting money on the least certain part in the system.

That alone does not prove it is bad. Some ovens take a little time to heat, and some cycle the broiler instead of holding a constant bright glow. Give it several minutes on a true broil setting before judging it.
Not definitely, but it is the leading suspect on an electric oven when broil alone fails. Confirm the setting first, then inspect and test the upper oven heating element before buying one.
Yes. If the sensor reads too hot or is otherwise out of range, the oven may cut the broiler early or heat weakly in more than one mode. That is why it moves up the list when bake and broil are both off.
Usually no, not first. Controls are less common failures than broil elements and sensors, and they are a poor guess-buy. Save that call for after the element, sensor, and accessible wiring have been checked.
It can be, if the job stays at the level of a visual inspection, a power-off continuity test, and a straightforward part swap. If you need to pull a heavy wall oven, deal with burned wiring, or do live electrical testing, that is a good place to stop and call for service.
