Re: Neff B1420 element & RCD trip fault
An oven element is like a light bulb… two minutes, twenty years… who knows.
However, on those ovens seriously check that the fan motor is okay. They have a nasty habit of running slow allowing the element to heat up in places giving a “hotspot” and the element pops. Obviously as they get older and more grease vapour ingresses to the motor it becomes more of an issue leading to what appears to be a premature fan element failure when, it isn’t really.
