The support is designed around a particular fit and heat arrangement. Placing it on another burner can make cookware unstable or alter clearances.
What the observation means
A generic ring can appear secure while missing the intended locating points. The wok and ring must both suit the appliance.
A useful next step
Follow the manufacturer's accessory diagram and use it only as permitted. If it rocks or moves, leave it unused. Do not bend pan supports, stack rings or hold the wok by hand as a substitute for a stable approved arrangement.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
