Describe the response
State what appears on the display after selection and whether a fan or indicator starts. Include timer or lock symbols as seen.
Leave diagnosis open
Settings, switching and heating faults may produce overlapping results. Assessment can examine the actual selected function and model rather than assuming that every cold oven needs an element.
A useful distinction
A temperature displayed after selection may simply be the requested value. Say what the appliance actually did afterwards, since a normal-looking number cannot establish that the cavity reached the chosen heat.
