Flood lights turn off after about 30 seconds...

I am a new home owner and may be the least handy person ever. I just found this site and hope that there is a lot to learn here.

At any rate, the flood lights in the back yard of my new house will turn on and only stay on for about 30-45 seconds, then they turn off. I thought maybe they were motion lights, but I walked all through the back yard once they turned off and they wouldn't come back on. So I go back to the switch and turn it off and back on and the lights won't come back on. After I wait about 10 seconds, I turn the light switch back on again and the lights come on again, but only stay on for about 30 seconds again.

I'm wondering if there is a problem with the wiring or something, any thoughts?

Welcome to the forums.

To determine if there is a motion sensor.
Try turning the switch on - off -on within five seconds and see what happens.

Actually.... what you are describing is a photocell sensor. You'd leave the switch on and then when night came..... they'd turn on. You can leave the switch off and then just turn on at night and they should stay on.

So why are they turning off after less than a minute?

If you turn them on in the daytime.... the photocell will turn them off.

When are testing them ?

If they don't have photocells.... First check the switch by disconnecting the two wires connected to it and connecting them together. If that doesn't fix it you need to check the connections in the boxes for the flood lights. Any wire nut connections need to be disassembled and redone, preferably with new wire nuts. Same goes for any wire nuts at the switch and if the switch wires were back stabbed before you tested after testing the wires need to go to the screws not the back stabs.
