No. A collapsed centre can involve the mixture, tin, timing or door opening as well as oven conditions. One cake is weak evidence for a thermostat diagnosis.
What the observation means
Start with what changed from a previously successful batch: ingredient quantities, tin diameter, shelf level, mode and preheating. A deeper mixture takes a different time to set than a shallow one. Opening the door early also changes the cavity conditions while the structure is developing. These observations help distinguish a recipe comparison from a repeatable appliance change.
A useful next step
Keep the recipe and actual settings together if several familiar bakes now fail similarly. Describe whether the outside browned before the centre set. Avoid compensating with an extreme temperature increase, and do not dismantle controls based on a baking result alone.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
