The elements and controls series

When part of an oven works and part of it does not, the oven has already told you something useful. A dead appliance can be almost anything. Half a dead appliance is a wiring answer: something that is shared between the two halves is fine, and something that is not shared has failed.
That single idea runs through all three parts. Part one takes the commonest version of it, a broiler that has stopped while baking carries on as though nothing happened, and works out what the two circuits have in common and what they do not. Part two is the version with no clues at all — a wall oven whose panel has gone dark — and sets out the order to rule things out in, starting with supply rather than with the board. Part three applies the same logic across two cavities of a double oven, where the second cavity is the best diagnostic tool in the house.
The three are written to be read in any order. What they share is a refusal to condemn a control board first, because a control board is the most expensive part in the cabinet and the easiest one to blame.
- Why did the broiler quit while bake still works? Half an oven working is the most useful fault a kitchen can hand you: what the two halves share is provably fine, so the answer is already down to the short list of things they do not share.
- Is a dead wall-oven panel the board, the fuse or the power? A dark panel gives you nothing to read, so it gets diagnosed by elimination — and the order to eliminate in starts at the supply outside the oven, not at the expensive part inside it.
- Why does only one cavity of my double oven work? A double oven hands you something no other appliance does: two ovens on one supply, so the half that still heats tells you where the fault is not. What the cavities share, what they do not, and the test you can run tonight.
