Check that the knob for the named burner is on its shaft and pushed fully home. If it comes back, it needs a visit. ### Can a SmartGrill knob come off in normal use? Yes, knobs pull straight off their shafts for cleaning and can be knocked loose. Pushing it back on fully is the first thing to try. ### Can I still cook on my Lynx SmartGrill with one bad knob? The controller only closes the burner for that knob, so the others can be used. The affected burner stays off until the knob reads correctly again. ### Why did my SmartGrill knob stop working after a hot cook? Heat building up behind the panel, often from wind, can damage parts behind the knobs. If the knob is on properly and still not read, have the panel checked. --- **[Read on the site: Lynx SmartGrill "knob has malfunctioned": the controller lost a knob](https://bbqgrillrepair.center/error-codes/lynx-burner-knob-has-malfunctioned/)** **[Book a visit with BBQGrillRepair.center](https://bbqgrillrepair.center/schedule/)**
