JBP79COB4CC Surface Light Flickers

[Swpstkr1]

My GE Spectra 30" Free standing oven/range has a fluorescent bulb that shines on the cooking surface. My best friend likes to use it as a night light.

Consequently, I have to change it every December, because it burns out. This last Dec. it was flickering so I figured I was getting a warning that it was going.

Ordered a new bulb F26T8CW4. Put it in and everything was fine until March 9 when it started flickering again. So, do I have a bad bulb or is there another

component in the circuit that may be bad? I would guess there must be a ballast in there but don't know what it looks like.

Make sure the bayonet fit of the ballast posts are clean and not blackened, or you will have a similar failure in short order... burnishing blackened metal and using a small amount of switch lubricant (or bulb grease, as it is sometimes referred to) can make the connection more resistant to this type of thing.
