The light bulb in our electric oven worked for a long time without problems; I can't remember the last time I changed it until recently. When it burned out a few weeks ago, I tried to unscrew it but the glass bulb came off of the metal base. I had to use a piece of wood to jam into the base and turn it for removal.

The new bulb lasted a couple weeks then burned out. I removed it in one piece and replaced it and now, after a couple weeks, it's burned out again.

Did I just get a string of bad bulbs or could there be another reason for the quick burn outs? We're not doing any unusual cooking, same frequency, duration, and temperatures as before.

You should measure the voltage. IIUC electric stoves use what I call
220V but the light bulb and analog clock when they had them, and
probably all the electronics now** use one leg of the 220 plus a neutral
wire to get what I call 110 which is usually 117, no higher. Higher
voltage will burn out bulbs.

What about other incandescent bulbs in your house? Are they burning
out faster than normal?

I have a feeling there's something I'm leaving out.


**Well, it starts off at 117 but is dropped to 12 or so for the
electronics.

Agreed.

Did you purchase a 130 volt 40 watt "Appliance Bulb"? If not, do so in
readiness for the next bulb burnout.

To help keep a bulb's base from "sticking" in the socket. just rub the
bulb's base on the sides of your nose while turning it a few times
before installing it. The "nasal sebum", a natural oil on your nose skin
will do the job.

When are you going to learn that the nominal voltage in the USA is
120volts and it has been for quite a few years now. :-?

No problem with the rest of the bulbs in the house, just the oven bulb. I'll try a voltage check.

I bought what was labeled as an appliance bulb but am not sure of the voltage rating. I'll check that when I get home.

I'm remembering a couple moments in my life where
one brand of bulb didn't last very long. And when
a different brand did fine.

Voltage check at the socket sounds like more work
than a different brand of bulb.

My clever plan to check the socket voltage is to screw in one of those receptacle plug things, then put the meter prongs into the slots. I'd probably electrocute myself trying to insert the prongs into a live socket. I will try to change brands if any alternatives are available.

If you are positive you got a light specifically designed for an oven,
then the socket itself is bad and will need to be replaced...possibly
the wiring too.


If you have low voltage that will not burn out the bulb

That should work. Ranges are often 240 VAC, and
if the neutral is bad, your bulb might be
getting too much voltage.

Use a bright flashlight and take a look inside of the socket for the oven light. If it is corroded or burnt looking, it should be replaced. The heat from arcing inside of the socket can kill a light bulb prematurely.

I've read you can use a potato to remove the base from the socket. Is
that safe?

I thought appliance bulbs were different ony in that they were covered
in plastic, so when they broke, you didn't get glass all over the inside
of the oven or the fridge or the dishwaher or clothes washing machine.

And maybe they are a little smaller too.

Safer than fingers. I'd be tempted to wear
gloves around broken glass. Might have to
use a knife to point the end of the potato.
