Yes, if the supports have designated positions or different shapes. Stable support and clearance depend on the intended arrangement.
What the observation means
A pan can rock even when each support seems to sit on the hob. An incorrectly located piece may also obstruct a burner or make cookware too close to controls.
A useful next step
Refit only as the manual allows while the cooker is cool. If a support is cracked, bent or incomplete, leave that position unused and obtain compatible advice. Do not pad it with foil, grind it flat or balance a pan across an unstable assembly.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
