Hi Wassam
Is the bulb you're holding in your hand (post #23 ) out of your Kitchenaid wall oven? The filament appears to have failed, so is that one you've replaced? It appears marked G9 120V 25W. Have you replaced it, and if so what with?
Thanks for the manual page.
There are also Kitchenaid manuals online for their range of 24" and 27"wall ovens which all seem to contain the same section on oven bulbs. But those on-line versions all say that bulbs are 120V maximum 40W.
I am bemused by this saga. When the OP first posted I tried to find a Sylvania capsylite 12V 2.5W bulb, but they don't seem to exist! then I tried 12V 4W or 5W, but they are all G4 base, not G9!
The Sylvania G9 capsylite range does not appear to include any 12V bulbs, they only seem to be made with 120V (or 240V) rating.
Capsule bulbs made to operate on 12V up to 5W have G4 bases (two straight pins), and their low voltage filament is a short stubby coil, not like the capsylite filament In all the pictures In this tread.
So I am really puzzled because none of the pictures in this thread stack up with the Kitchenaid manual's that Utreas and Wassam have, saying to replace with a 12V 5W bulb. I don't believe you can even buy a 12V 5W bulb with a G9 base to fit the oven.
I'm really hoping to hear from someone who has replaced an oven bulb in a Kitchenaid appliance, as to what they have used!
