My La Canche oven keeps fusing. Has a gas hob and two ovens ,one is electric and one is electric fan.

call for service under warranty or call number in your manal

Typically on the back of the oven there is an access panel at the top behind the control's should be a circuit board with a fuse ?

See if the La Germania manual I posted on a ggogle drive will help you:

I have a Rangemaster and like yours is dual fuel. Gas hob and electric oven. The large oven is fan assisted but the small oven, on the right hand side of the range) is self cleaning and not fan assisted.
Hope that helps.

water has gone into back of element or oven light you will need to remove the back of the machine a check they are dry WITH THE POWER OFF

If the fan is working o/k, then you need to replace the oven element.

Hi.
You will need to check the oven element, it probably needs replacing.
Please rate my solution.
Thanks.

it could be your air to gas mixture is too lean, and the flame is blowing out. the oven will then turn off, but it is producing a lot of carbon monoxide have to see flame to really tell.
