Then look for a lock symbol: every one of these has a documented way out, usually holding one pad for several seconds. ### The free answers, which are commoner than they should be Control locks. A pan or a cloth left on a touch surface. Water under something. Demo mode set in a showroom and never cleared. Between them these account for a genuine share of the calls that arrive as a failed control, and every one is sorted in a minute at no cost. We would much rather find one of those than sell anybody a board. ### Panel or board They are different parts at different prices. Uneven response across the pads points at the panel; total silence from a dry, unlocked surface points at the board. Separating them is a test rather than an opinion, and it is the difference between two very different invoices. The control lock Set by accident, cleared in seconds once you know the sequence. We will tell you the sequence over the phone at no charge — it is not a repair. Moisture on or under the panel A wet surface, a cloth, or steam finding its way behind the glass. Dries out, or does not — and which one decides whether this is free. The touch panel itself Uneven response across the surface points here rather than at the board, and it is the cheaper of the two parts. The switch behind a knob On gas, the switch that fires the spark; on radiant, the infinite switch that meters the element. A knob that turns properly and does nothing is one of these. The control board Last, after everything above. A surface that responds to nothing at all with a dry, unlocked panel is the case that points here. Dry it and clear it Nothing on the surface, nothing damp. Then try again. Look for a lock indicator A padlock, a key, or a letter L depending on the model. A full minute at the breaker Long enough for the control to lose state, which the power pad will not do. Does one area work Partial response is the panel; no response at all is more often the board. Check the lock before the board What it usually means Some pads working and others not A lock symbol nobody can clear A knob that turns freely and changes nothing The fastest diagnosis is what you can see Dry the surface completely, take everything off it, and try again — these panels sense through the glass and a film of water, a damp cloth left across it or steam from a pan directly beneath will all make a healthy control behave like a failing one.

Separating them is a test rather than an opinion, and it is the difference between two very different invoices. ### There is a lock symbol and I cannot clear it. Every model has a documented way out and it is usually holding one specific pad for several seconds. It is worth finding rather than guessing, because repeated random presses trigger a further lockout on some controls. If the manual is gone, give us the model number and we will tell you the sequence — no charge, because it is not a repair. ### It works when the cooktop is cold and not when it is hot. That is a genuine pattern and it usually means the panel or its connection is heat sensitive — either a ribbon that has degraded or a board that is being cooked by poor ventilation underneath. Worth mentioning, because it points at a cause rather than only a part. ### My knob spins without doing anything. That is mechanical rather than electronic: a collar, a shaft or the switch behind it. Inexpensive, stocked, and among the quicker repairs on this site. --- **[Read full article: Cooktop controls not responding](https://bertazzonimiami.support/symptoms/cooktop-controls-not-responding/)**
