When it goes wrong · Broil
One end dark, the other pale.
Can you save it?
Reviewed for this symptom
Rotate the tray so the pale end sits under the hot part of the element, and shield the dark end with a strip of foil until the two match.
How to confirm the diagnosis
Observable cues, not inferred user state
- One end coloured well before the other
- The tray was not turned
- The same end darkens every time
Not this?
- Burnt in the time it took to turn around.
- Browned on top, cold in the middle.
- Smoking heavily and tasting acrid.
What actually happened
Only this symptom
Broiler elements rarely heat evenly across the cavity. Rotate the tray halfway, and expect a hot spot.
The full mechanism
Shared by every broil failure
A broiler is a grill turned upside down: almost all the energy arrives as radiation from directly above, and radiant intensity falls off sharply with distance. That relationship is the whole control mechanism — moving a tray from the top shelf to the middle roughly halves the heat reaching it, which is a far more useful adjustment than the on/off dial most broilers offer. Because the energy is so concentrated at the surface and so weak by the time it reaches the interior, broiling cooks the outside far faster than the inside. That makes it excellent for finishing something already cooked, for melting and browning a topping, or for blistering pepper skins, and unreliable for cooking anything thick from raw. There is no thermal buffer, so the window between browned and burnt is measured in seconds.

What right looks like
Shared by every broil failure
- Colour changes visibly while you watch — if nothing is happening within a minute, the shelf is too low.
- Cheese bubbles first at the edges, then blisters in the centre; that is the moment to pull it.
- The distance from the element is the real setting. Close for blistering, further for anything that needs a minute or two.
- The door stays open a crack on many ovens, which keeps the element on continuously rather than cycling.
