Also, LED bulbs can screw with the signal. Had the same thing happen to mine, switched back to incandescent bulbs, presto. Not sure if CFL bulbs do the same thing or not, but definitely led.
I believe you can return it to reelcraft to have it repaired. Im pretty sure we have sent some to them for service. They are fairly local to me, only half an hour away from me. Call them up
