What needs separating?
A fan oven running cold, a grill not heating and uneven cooking need different records. Mention each function you used normally rather than performing new tests.
For “food cooks unevenly”, potential assessment areas include mode selection, fan movement or temperature sensing. The product and an inspection determine which explanation, if any, fits.
A short record of this change
Note the shelf position, chosen mode and whether one side differs. Include the setting and the first stage that differed from normal operation, without assuming why it happened.
The cavity, mode and temperature selected
Which lights, fans or grill functions responded
The cooking result or point where power stopped
Identity before interpretation
Photograph a visible label around the door opening. For two cavities, keep the overall model and specify upper or lower oven rather than sending only a fascia photograph.
Access without dismantling
Built-in, built-under and high-level installations involve different access. Say where the oven is mounted and leave cabinet fixings and electrical connections undisturbed.

Keep an unsafe appliance out of use
Repeated restarting is not a diagnostic method. Leave covers fitted and stop for smoke, burning, sparking, water near electrical parts, severe overheating or repeated tripping.
Bring the details together
Complete only what you know. The notes remain in this page until you copy them; opening the booking service does not send these notes automatically.
