Are you suggesting that a built in one would not have an Aluminium fan in it then ?

Are you saying you can’t use your AEG oven because of the aluminium fan? Does the oven have the facility for conventional heating as opposed to fan oven heating? If so you could have the fan blades removed and just use it in conventional oven mode.

My AEG has 2 ovens
Bottom one is fan assisted
Top one is conventional
Both are Enamel interiorHowever cant use either of them because apparently theres an Aluminium chanell at the back which connects both ovens to the fan
and the whole oven is encased in foil
Its the presence of Aluminium which when its heated gives off a kind of radiation that affects the food
Its hard to describe how it does that but sadly it does …………too many people think just because they have ditched Aluminium Saucepans they are safe
I spent 2 yrs in a wheelchair 20 yrs ago was dreadfully ill with Aluminium poisoning and came so close to dying i am not prepared to do it again …….i am as a result severely allergic to the blasted metal and least contact with it causes nasty symptoms

Possibly not, I was just trying to give a few more options of suppliers who produce a higher spec machine where the fans may not be aluminium. Coupled with the fact it could replace the AEG in the housing. You could then sell the AEG and realise some capital return.

Not likely to sell the AEG for much
and its OK for other family membershence why i have always had the Sharp combi
Still cant work out where the fan was if it ever had one because i sure could not see it and i can clearly see them on every other model i look at

Hi
Even if you get a microwave without an aluminium fan the magnatron (the bit that radiates the microwaves )is encased aluminium.

So how come I never had any problem whatever from the 15yr old Sharp Combination Microwave/grill/oven
that gave up the ghost last weekWere the old ones made differently ?
It certainly did not have a visible fanMay 25, 2008 at 9:22 pm #252398kwatt

Nope.

Perhaps not visible, but it would almost certainly have had one. Put it this way, if it didn’t have one then it’s the only combi I’ve ever heard of that didn’t have one to drive the air or expel it.

So if it had to have a fan where would they have hidden it
If I looked inside
There was only the seamless stainless steel lining
the element under the turntable
the magnatron cover
and the quartz element/grill at topThere simply was no grill /perforated setion in front of a fan blade as there is in all the new ones
I need to find the instruction manual for the model numberIts not a matter of needing a medical opinion …….that i can assure you

Okay then… so…
How did the heat get distributed then? You either use convection, which is slow, radiated heat (infra-red pretty much) or you use air driven heat.
That’s it.
Convection – no fan.
Anything else, involves a fan and, in a small cavity cooling is important so I’d guess that there was some form of cooling fan. Add to that you have, as you say,a sealed cavity then you most certainly need to expel hot air and that would need a fan of some sort.
It’s gonna be REALLY hard to find an oven that doesn’t have aluminium in its construction… really hard indeed if not impossible.

I still think the easiest option would be to get the Existing oven modified to replace the aluminium parts with a different material and replace the old combi with an ordinary microwave. As stated, the magnetron fins are aluminium but I don’t think they should get hot enough to give a problem (which is why they didn’t cause a problem on the old Sharp).

ParticipantRe: Combination microwave ovens >>>>>>>
OK
Any ideas who would /could modify the existing oven

KeymasterRe: Combination microwave ovens >>>>>>>
I don’t know of anyone with that sort of ability outside factory, there’s been absolutely no call to modify an oven in that way that I’ve ever come across. In any event to do so would be extremely expensive as you’re looking at custom built components to do it.
The only oven that you can almost guarantee won’t have much, if any, aluminium in the construction is an AGA and even they may use foil backed insulation, I don’t know as I’ve never worked on one.
Even static ovens are getting rare these days and that’s about all I could suggest without going to silly money, so long as it had a sealed cavity, but even that’s rare as they usually have a vent on them somewhere which is often fabricated from aluminium.
As for a microwave that’s aluminium free, I don’t think you’ve a snowball’s chance of finding one in all honesty. And, there’s not a prayer of modifying one so that it doesn’t contain aluminium, no-one’s going to take that on.

Only if a link can be proven which, from what I can see, is tenuous at best. However this is not the website for such a discussion and, I’d suggest, that you vent your frustration at the manufacturers to comply with your requirements or to lobby government to legislate the matter on health grounds as that is the only two ways that will bring about change.
We can do nothing to help you with your problem avoiding aluminium.
