Burnt out light bulb ?

I agree I'd not switch to LED.. You should be able to do it yourself. however one word of caution.

There are two ways the lights are repalced. One you simply remove a cover INSIDE the Oven and you can access the bulb (Actually 3 ways now that I think of it)

3rd way is a access cover OUTSIDE the oven

2nd and I think this is most common you have to remove the outer housing. IF yours is like this be careful of SHARP EDGES on some of the internal metal parts.

Manual said requires an authorized service tech. That usually means it was designed by an engineer without common sense, meaning that you have to pull the case off.

Probably an easy task, but I do this kind of work daily.

Hopefully it uses common components, but you may have to order some exotic bulb that the same engineer designed into it.

Still a lot cheaper than taking it to a repair shop.

i copied this from one of the apollo manuals

My light bulb is out

they always say that don't they? was in the service section of the manual. usually they are only accessible by taking the outside cover off. i have never looked at that brand though.

I don't think it is a good idea to put a plastic LED in a convection oven. :W

surely somebody here has switched their bulb to an LED to limit parasitic loads.
