Any guesses as to what might be wrong - and how I can fix it easily, quickly and cheaply
I have a freestanding smeg cooker and this morning the oven would not heat up on the fan setting. Fan comes one, thermostat light on the front comes on - but it blows cold air I left it cooking DS2s roll for far too long before noticing this morning that nothing was happening and he had a parbaked roll for lunch oops
It works fine on the conventional setting - heats up to temperature.
Model seems to be Opera 90cm - A1DNA-6 if that helps.
Wild guess to be honest Replacing the bulb is the limit of my oven diy activities. But I've heard of faulty elements as A Bad Thing. Its the only other thing I've ever heard of to go wrong with an oven.
very likely the heating element. They don't last very long and are a replaceable service part (like tyres on your car).
A competent handywoman can change it, after isolating the power supply you will have to unscrew enough of the oven lining to take (usually) the inside back panel off, and you will see a probably round element coiled round the fan. It plugs in.
