Oven Bulb Blown Electrics - Voltage Question

saintscouple

Hopefully there is a 'bright spark' who can answer this for me.
I fitted a replacement bulb in the oven yesterday, turned the oven on immediately aftwerwards and all worked fine.

Today on using the oven properly the bulb blew, and took with it the electrics.

I've now managed to find the oven user manual online, and it states to use a 220-230v 25w ses bulb, whereas i had replaced it with a 240v bulb.

Question is would the incorrect bulb voltage caused the blow out, or am i looking at something more sinister i.e bulb connector shortening somewhere?

The oven works fine without the bulb, and to be honest if it is something more sinister we'll leave it as it is and save the cost of getting a correct voltage bulb.

Thanks for any advice given.

A bulb blowing and taking out a trip is quite common and there isn't anything you can do about that.

The reason it blew could be that it wasn't designed as an oven bulb - make sure you only put in an oven bulb.

I've no idea why this happens as an oven only gets to ~ 200C max and the bulb filament is several thousand but I've had exactly this problem when using bulbs that didn't say for ovens on the pack.

Sorry, I should have said that it was an oven bulb i used.

Problem was i used a 240v one, when the oven manual states to use a 220-230v one, and was it because of this the electrics blew?

I'm not sure it would, as the oven requires 220-230v i thought a bulb voltage of anything less than that would blow and not 10v more. But i'm not a sparky and don't want to waste £5+ on another bulb of the correct voltage if it's likely to blow again.

Is the 240v bulb exactly the same size and shape as the 220-230v bulb.

I know with my oven I did the same and put a higher voltage bulb in, the higher volt bulb was slightly bigger, it was touching the protective cover that goes over the bulb and it blew very quickly. Since putting the correct bulb in there hasn't been a problem, this was months ago.

Ahhh, interesting.....we only recently moved in to our house, where the oven was left for us, and the light had never worked.
The one i pulled out of the oven was a 240v, the same one i replaced it with.

Looks like it will be worth buying a 220v bulb then and see how it goes. Guess either way that will answer my question.

Many Thanks for posting your reply, at least now i have a little hope the correct voltage bulb could work.

In fact, for a given wattage a higher voltage rated bulb will glow slightly dimmer, putting less strain of the filament.

Are you using the correct wattage bulb for the oven?

the voltage is fine, dont obsess about it. its not that, try another oven bulb. you may have bought a duffer.

Agreed, the voltage is immaterial in this instance, in fact the higher voltage would be better.

The only problem would be if used say a 110v lamp instead of one around 220v

Bit of geek technical info...

The 240v we use is actually only around 230v (there's a +/- 10% fluctuation) The "240v" is just the standard rating.

It might have just been a duff bulb tripping the main circuit breaker/fuse.

The voltage rating is immaterial in this instance - mains rated bulbs can be marked anything from 220 to 250 VAC, but they are all fine. Oven bulbs can be fragile bleeders and it's not unusual for them to blow shortly after replacing in my experience. I can't imagine anything wrong with the cooker which would cause a bulb to blow. It's either been a faulty bulb or a mains surge I'd guess. Just try another bulb.
