cooktop problems and troubleshooting
start with the guide that matches your cooktop: an unresponsive touch panel, a damaged knob and a gas ignition problem are different issues. gas and internal electrical repairs need qualified help.
common problems7
- how can i check stubborn marks on ceramic or induction cooktop glass?some marks that look beneath the glass are surface deposits. clean only intact glass using its approved method; cracks or damaged coatings need assessment.
- what should i do if my cooktop control knob is cracked or slipping?a damaged knob and a stiff or unsafe underlying control need different repairs. never turn the exposed shaft with tools.
- why are my cooktop's touch controls not responding?moisture, grease, objects on the sensors or a control lock can prevent operation. start with a cool, clean, dry control surface.
- why are the flames yellow on my Fisher & Paykel CG604C or CG905C cooktop?wet or blocked burner ports and gas-supply issues need different attention. persistent yellow flames need a licensed gas check.
- why does my electric hotplate stay too hot on a low setting?compare the change with normal cycling, then stop using a hotplate whose heat no longer responds to the control.
- why does my gas cooktop knob no longer trigger ignition?record whether clicking has stopped at one control or several, without releasing more gas to test the fault.
- why is my induction cooktop not detecting a pan?check induction suitability, the base size and the pan's position. stainless-steel appearance or overall diameter alone is not enough.
common solutions7
- how to check a cooktop hotplate heat-control faultrecord which electric hotplate overheats without repeating the fault. a qualified repairer checks the regulator and the exact control-position wiring.
- how to check a damaged cooktop control knobcheck the knob, insert and marker without forcing the spindle. on BG4S, repairs are directed to an authorised service agent.
- how to check a gas-cooktop ignition-switch problemrecord whether one or several knobs fail to trigger ignition, then stop testing. a qualified gas-appliance repairer identifies the faulty ignition component.
- how to check cookware when an induction cooktop cannot detect a pancheck the pan's induction suitability, base size and position. compare a known suitable pan containing food or liquid, not an empty-pan test.
- how to check wet or locked cooktop touch controlsremove items from the sensor area, then wipe and dry it once the zones have cooled. use the model's normal unlock sequence rather than guessed button combinations.
- how to clean residue from intact ceramic or induction cooktop glassuse the cleaner approved for the intact glass or coating. a purpose-made scraper is conditional on the manual; damage and hot sugar spills need separate handling.
- what to do about yellow flames on a Fisher & Paykel gas cooktopstop using affected burners and arrange a licensed gas check. report whether the change followed cleaning or installation without adjusting gas parts.
