Many radiant and induction cooktops are run by touch keys under the glass, and those keys are built to ignore input they cannot trust: water, a wet cloth or a pot parked on the keys will lock them out. A control lock, a showroom mode, or a cooktop that shut itself off after a set time can also look unresponsive. When none of that applies, the touch board, a ribbon cable, or the power supply to the control is the likely cause. On knob-controlled cooktops, a knob that does nothing usually means a broken knob, switch or valve stem. The 5 causes, cheapest first Answer these first 01 Is a lock symbol or a key symbol showing on the display? 02 Is the glass over the controls dry and free of pans and cloths? 03 Do some keys respond while others do not? 04 Does the display light up at all? 05 Did it begin following an outage, a spill or a wipe-down? ## Check these before you book. Cooktop controls unresponsive: 5 checks, and none of them costs anything. 01 Dry the glass over the controls and take any pans and cloths off it. 02 If a padlock symbol is lit, press and hold the lock key for the time given in the manual. 03 If any zone heats while the controls ignore you, switch off the breaker and leave it off. ### Also worth checking - Turn the breaker off for a few minutes, then back on, to reset the control. - Note which keys or knobs respond and which do not. ### How soon does it need a visit? Unresponsive controls are not urgent on their own; try the lock and dry the glass first. It is urgent if a zone keeps heating while the controls ignore you: switch off the breaker and book a visit. ## The causes, cheapest first. 5 things cooktop controls unresponsive turns out to be, from control lock switched on to touch control board failed. [The cost guide](https://cooktoprepair.center/cost/) 1. 01 no repair ### Control lock switched on Most touch cooktops have a lock key that must be held for a few seconds to release. The manual gives the key and the time for your model. No repair: check it yourself 2. 02 no repair ### Water or a pan on the touch area Liquid, steam condensing on the glass or a pot left over the keys makes the control ignore input or shut down. Dry the area and clear it. No repair: check it yourself 3. 03 low ### Knob cracked on its stem A knob that spins freely has split inside and no longer turns the switch or valve behind it. [Fixed by infinite switch and knob repair](https://cooktoprepair.center/services/infinite-switch-and-knob-repair/) 4. 04 low ### Ribbon cable or connector loose The touch board and the power electronics are joined by cables that can work loose or corrode, especially after a spill. [Fixed by touch control repair](https://cooktoprepair.center/services/touch-control-repair/) 5. 05 moderate ### Touch control board failed A board whose sensing circuit has failed stops answering some or all keys, even dry and unlocked.

Most show a key or padlock symbol, and some beep at any press. Holding the lock key for a few seconds usually releases it. ### Why do the controls stop working when I wipe the glass? A damp cloth over the keys looks like a finger on all of them at once, and the control shuts down to be safe. Let the area dry. ### Can a power outage affect touch controls? Sometimes. A surge, or power that dropped for a moment, can leave the control in a muddled state. Cutting the breaker for a few minutes usually clears it. ### Can the touch panel be replaced without new glass? On many models the board sits separately under the glass and is replaced on its own. On some, the keys are part of a top assembly. --- **[Read on the site: Cooktop Controls Unresponsive: Causes and Fixes](https://cooktoprepair.center/problems/cooktop-controls-unresponsive/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
