No. Several faults or operating states can produce a similar lack of heat. A symptom match helps frame an enquiry but is not a component test.
What the observation means
A fan running, lamp glowing or clock working each shows a different function. None independently proves that the selected heating circuit has the right supply or control. Replacing a part on that evidence can leave the real problem unresolved.
A useful next step
Describe the affected mode and the observations already available. Leave internal electrical testing to a competent person. Do not remove a rear panel or order by visual similarity simply because another owner's oven behaved in a comparable way.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
