The fluorescent lamp on a Kenmore Model 250 stove (now
20 years old) has started wrecking new fluor. tubes (Sylvania, 22-inch, 18 watts). Symptoms are:- Dark grey bars appear at both ends of the new tube within 5 min. use.
- Tube lights only at the two ends (dark in the middle for 18 inches.) One end shows white light, the other pink light.
What does this mean?
