Hi shealy,

I'm Harvey the Master Plumber.

Your problem is: This hood worked fine until a light bulb blew out. Put in a new light bulb, but the lights will not turn off. Is the light switch bad or is there a problem with the control panel? The fan still works fine but the lights will not turn off or adjust dim or bright.

You're on the right track. The light control switch needs replacing. You might try utilizing the Repair Directory to find a repairman. If you have the tools and ability just remember to turn off the electric first.

Feel free contact me again!
