faulty Fan Oven Elements on Zanussi ZBF 760

[harry79]

I have a built in oven/grill (Zanussi ZBF 760). The hob is gas and separate to the electric oven/grill unit.

Clock works fine, however when I turn on the oven several mins later it blows the master trip causing loss of electricity to the whole house, cooker circuit switch untripped on the breaker however.

This does not happen with the grill element!

I have removed the back panel of the oven and see that possible it is the fan element responsible for this problem as the master trip is not triggered when the grill is working.

The fan element does intially work, but suspect that it is overheating and this is why the trip switch is triggered after several mins.

I would like some advice, before going head and buying a replacment fan element?

Thank you

only thing it can be is the element or the fan motor
if you put on the fan oven with no heat and it doesn`t trip it must be the element

Reading the above and realising that it could not only be the heating element even thought it was the end result as I perviously mentioned.

What I found was the extract fan blades where not rotating even though the motor inside was humming and causing the element to over heat and to trip the switch,

I remove the fan blade and cleaned the joint that it rotates on, removing grease built up over the years and it works fine now.

I have a learn alittle more about my oven, thanks you to UK whitegoods forum, saved me money and time!!!! :

If there is anything other advise? It is always welcome

yep. change the element at the earliest convenience

it tripped because it expanded, due to lack of airflow, cracked, and allowed moisture ingress – the cracks will still be there!
it WILL go again, so id recommend changing it before it goes again, allowing things to keep tripping will, ultimately, cause damage to the stat/clock/selector

hope this helps
