Roger, DO NOT USE. Return to place of purchase, or cut cord and discard.

If you know the bulb is good, try changing the photocell. Why is it half of the problems on this site are Utilitech? I think I see a pattern.

I called Lowes then Utilitech and they sent me a new impeller. There were no instructions about how far to thread the impeller onto the post. I am going back in to thread it all the way to the top. I wish I had requested a brass impeller.

Is there water over the pump housing? Is intake on the bottom clear of debris? This may sound stupid, but is hose frozen or blocked?

impeller is probably chewed up
