i keep blowing cooker elements, is my wiring safe?

[paulnuccs]

I need some help with the wiring to my electric oven as I keep blowing the element in the main oven.

What do you mean by blowing? are they going open circuit? Tripping RCD/circuit breaker etc. I've seen fan oven elements have a shorter life when the fan is running too slowly, such as high friction in the fan motor.

As Freddo says but this problem can also be caused by a broken thermostat for the oven.The oven stat never clicks off and the element keeps getting hotter and hotter until it blows itself.To check the stat,put the oven on at 50 degrees c and give it a minute.It should click off at 50 and then turn it up to 100 and it should click off when it reaches 100.If the stat doesn't seem to be clicking then its faulty.
Another side point is that if the oven element is the back one with a fan in the middle then make sure that a: the fan is spinning and b: the cover is put back over the whole back area or else this will blow the element as it needs the air to be circulating around with the fan and the cover in place.

It is very unlikely that a fault in your wiring could damage the elements. If you have a normal single-phase consumer unit and meter, and none of your other electrical appliances or lights are behaving strangely, then any underlying connection between the element failures is probably within the oven as stated above.

How long do the elements last?

 

[paulnuccs]

this element lasted just over a year, I think the problem maybe the cooker switch socket as it also has the oven hood and a double socket wired into the back of it

this is now the second oven in 3 years that has had the same issue. I have noticed that the cooker hood and an extra double socket are all wired into the cooker switch. could this be where the problem lies

Where these the same make of ovens, bought from a retailer?

Well that doesn't sound right for a starter. Possibly not the issue, but certainly not right?

I'm thinking clearance warehouse 2nds no offence intended.

both new ovens, different makes though

I've checked the technical info on the oven and it says its 40A, the main fuse Is a 30A is this an issue

not really as the oven will not draw anywhere near 40A due to diversity ( that's because you won't hav all elements on at the same time and the stat/s cut them out. a 30A fuse will withstand 40A for somewhere around an hour.
