Replace Oven Halogen bulb.

[UTreas]

Current Oven bulb is Halogen G9 base 12.0V 2.5W, 5W Max per manual; Exact replacement not available. Best match is 120V 25W bulbs. Is it advisable to use these? in general why are oven bulbs low voltage? Thank you

Welcome to the forum mate.
A 120V bulb will not work on 12V

What make and model is your oven?
have you tried contacting the manufacturer to see what they say about the bulbs?

I would have to say no since you stated 5 watts max per bulb I don’t think the bulb base will get to hot. I’m not sure about the low voltage on your bulbs, mine is 120vac

Could it be 120v not 12 . 0v? Is it possible that the decimal is infact just a little spot of dirt? It is unusual for a bulb to have a voltage rating with a decimal point printed on it.

I've never come across an oven with a low voltage lamp. All have had a lamp that runs at the full supply voltage, except for one, that had two lamps in series.

I would be willing to bet it’s 120vac. Good luck

That is (possibly a copy of) an Osram sylvania 66725 oven 120v 25w 2800k g9 halogen light bulb
of which there seems to be a complete shortage of stock everywhere!
There are similar things available, but I don't know if they are rated for the oven environment, eg:

https://www.amazon.com/Dimmable-Halogen-Clear-Bulbs-Capsules/dp/B08WM725J9/

There seems to be confusion over the rating - for example, where did the suggestion that it was only 2.5W come from - you suggest the manual says 5W max, but I don't think they ever made such bulbs in 5W rating.

Manual for the appliance indicates 5W max. The original bulb is Sylvania Capsylite G9 marked what I read as 2.5W and 12 V. thnak you for the guidance. Unable to get any informaiton from the manufacturer Ktichen Aid/Whirlpool. Their site is selling a replacement bulb for ~34 USD.

 

[James]

I read that as 120v (on the lamp picture)

 

[SJD]

I read (after saving & enlarging) the lamp as being 120V 25W.
Just that the lettering is badly spaced so it appears to be something else.

 

[brianmoooore]

Not really helped by the fact that the numbers and lettering are composed of printed dots, so difficult to say where the number ends and a decimal point, if any, begins. To me, it reads 120V and 25W.
The 120V can be checked by measuring the voltage or temporarily fitting any 120V G9 lamp, and 25W is about what I'd expect an oven interior light to be rated at.
I fitted a couple of 2.5W G9 lamps earlier in the week, but they were LED types, and the equivalent brightness to about 25W halogen.

thank you

 

[Avo Mk8]

thank you

I'm still intrigued by this issue.
On further research I see there are indeed Kitchen Aid/ Whirlpool ovens that do use 12V 2.5W or 5Watt bulbs, example below.
But the markings on such bulbs are very clearly just 12V - no spurious zero after the 12 for example, and they have a different G4 base.
Could you clarify, is your oven a microwave or a conventional oven? And could you tell us the model number?

This lamp has a G4 base, not a G9. Theses aren't uncommon. I just changed a whole batch of them for LED equivalents in my newly acquired caravan

The lamp in @Avo Mk8 link states they are G9 and they look like G9 to me.

Brianmoore was commenting on my previous post #14 - I was showing the G4 12V 5W version is used on the same brand of appliance the OP has (I'm not saying necessarily on his oven), but it's on a G4 base as I commented.

 

[brianmoooore]

That's the point I was making: G4 is extra low voltage, G9 is mains voltage. OP's lamp is G9, so will be (US) mains voltage = 120 volts.

You can use the G4 Bulb. The only difference with the G9 is the shape of the metal prongs which you can bend if needed.

You can find the same spec bulb 12v 5W for much cheaper

and if he's shoving 120V up a 12V bulb??? bumps a daisy.

I didn’t want to put a disagree red mark against your first post, but it is important to read the details thoroughly before offering advice

 

[Wassam]

I’m being questioned on my advice here. Fair enough.

I have a Kitchenaid Wall Oven using the identical bulb. In the manual for the oven, it states “The oven lights are 12-volt, 5-watt maximum halogen bulbs.” I see a few posts here saying to get a 120v bulb and although misleading based on what’s written on the bulb, I trust the manual.

Interesting mate. Personally I'd go with what the manufacturer has put on the bulb rather than the manual.

Any change of taking a pic of the manual where it states the bulb requirements and posting it up on here.

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.

https://www.energyavenue.com/forms/INV/3437S25T4G9CL_CAPSYLITE_G9_Lamps.pdf

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!

 

[Wassam]

It’s bizarre I know. Another KitchenAid wall-oven Manual I read had the same instructions for replacing the bulb with 5W 12v G9. The instructions I included in my last post was specifically for my wall-oven.

The picture I posted is the original burned out bulb I am replacing. I ordered the G4 12v 5W bulb and it should arrive soon for me to try. Worst case the bulb bursts because it received more voltage and wattage that it can handle.

 

[brianmoooore]

There are a few 12 volt G9 lamps available on line, but all that I've seen are LED versions, and aimed at the "off grid" community.

I'd love to know:
a) what bulb they send (ie does it look the same construction as the one you have?)
EDIT: just used your link - as it stands I don't think that will connect with your G9 base. You suggested bending the pins, but that might break the glass to metal seal. Also to me it's not in any way the same bulb as your faulty one!
b) what happens!
If you get a chance, do post the outcome
Regards.

 

[Wassam]

Yeah I'm leaning now towards just using what's written on the bulb as the spec. Getting a G9 120v 25W bulb.
Bulbs options: Example 1, Example 2

They look good. I would go for one that specifically mentions suitable for an oven (like Example 2), as it has to work in a slightly higher temperature environment than in a normal light. Otherwise their life could be shortened.
Hope it works out

Hi all, to close the loop on this thread, I bought this 120v 25W bulb and it worked fine with my Kitchenaid wall oven. I guess the moral of the story is, don't believe everything you read in the operating manual!
