Remove loose contents and follow the drawer's own care instructions. Its purpose and permitted items should be confirmed from the model guide.
What the observation means
Food debris, packaging and utensils can hide damage or obstruct movement. A drawer under an oven may become warm, so it should not be treated as unrestricted household storage.
A useful next step
Clean only owner-accessible surfaces while cool. If the drawer catches, smells of overheating or contains melted material, report that separately. Do not dismantle the cooker chassis to extend cleaning access or store flammable cleaning products there because they fit neatly.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
