electric oven stopped working suddenly

[nitgel]

Can anyone help? yesterday I steam cleaned it and replaced the bulb which was blown. It came on fine for an hour then just went off.

Any advice

If it’s a Stoves make or similar there is a cut off switch, which usually comes on if it overheats. Steam cleaning may have skewed the sensors. Needs an experienced oven engineer to check it and reset.

Have you accidentally swithched it over to timer mode?
