NEFF electric oven glass viewing panel

Hi All,

We inherited a NEFF double oven when we bought our new house. The glass viewing panel (the inner panel of what's effectively a double glazed door) was becoming detached and finally it's become so detached that I decided to see if it could be repaired. It appears the glass panel on the inside is attached to the metal frame of the door using dark brown silicone sealant - that's all. But the silicon was caked in the oily cooking residue of ages. I have cleaned it pretty much as much as I can, but of course the sealant has no desired to adhere to the cleaned glass panel. Ideally I'd like to replace the sealant, having thoroughly degreased the door frame and the glass, but I suspect the sealant may not bog standard silicone sealant from Unibond. Can you advise me what the correct sealant is, where I would get it, and how long it might be expected to require to cure? I presume that the sealant needs to withstand tempertures of ~200*C. If the sealant is not easily available, would it be possible to use an alternative bonding agent on top of the degreased old sealant. I'm a great fan of Araldite. Would that adhere, and withstand 200*C?

Thanks for your help and advice,

No. One way of breaking an Araldite joint is by heating it up.

I would contact the manufacturers for advice regarding the sealant, or have a word with a local electrical appliance service/sales shop. It looks as if you need something a little better than a squirt of No More Nails. No results from Google?
it is bog standard silicone sealant from Unibond and 24h to cure

I would very much doubt that. Ther are VH temp sealants, such as item 360073022183 (1200 deg) and item 230273368352 (300 deg) on ebay, but whether they have the adhesive capabilities to hold the glass panel is another matter (they seem to be more sealants than adhesives).

Thanks for the advice. It appears that there is specific silicone. I found item code 120285931007 on eBay myself, and it has a recomendation from a user who has experience sticking his glass door back together, so I've purchased that. As the door is still attached to the oven (and I'm not going to dismantle that 'engineer's wet dream' of an assembly) I'll need to secure the vertical glass in place with duck tape while the silicone goes off.
We'll see.....

Thanks and Best,
