Describe what stopped
Say whether indicators, fan and display continued when heat seemed lost. Include any warning already seen rather than guessing a failing part.
Compare one ordinary pattern
A fault that occurs after warming differs from one present at start. Assessment may need that sequence to decide what to inspect; a single remote description cannot prove the thermostat or element.
A useful distinction
Heat cycling can be normal, whereas a programme that never recovers and leaves food uncooked is a changed outcome. Describe the complete result so the enquiry does not rely only on feeling a temporary pause.
