Name the function that changed
For an oven, retain the selected function symbol, temperature setting and affected cavity. A fan turning or a lamp lighting does not show that heating is working normally. For a cooker, say whether the concern involves an oven, the grill or the hob, and tell the booking team the fuel type before discussing suitable work.
Keep results separate from diagnosis
Food browning unevenly, a cavity remaining cold and a programme cutting out are different accounts. Describe the result you actually saw without repeatedly reheating the appliance or taking internal temperature readings. Gas-related concerns must be discussed before a booking is accepted; this site does not promise every fuel type or fault can be attended. Other Farnborough appliance categories are listed on this page.
