Power Supply 99956034US (120W Basic) FAQ
How do I know if my power supply failed vs. the robot motor?
If the blue power LED does not illuminate when plugged into a tested GFCI outlet (even with the robot unplugged), the power supply needs replacement.
Where should I keep my new power supply?
Always keep your power supply at least 12 feet from the water's edge in the shade, elevated off wet concrete (such as on a Universal Caddy).
