    It's probably a bad switch somewhere. Recreational metering for line voltages is never a good idea, though.

    The manufacturer should have a web presence, and that can be a way to get a wiring diagram. With that in hand, you can check for proper operation with the tanning bed unplugged, just by reading for continuity on the ohms setting.

    If you can expose the wiring, it's also not too hard to follow the current path, but that is another exercise best done with the bed unplugged.

    The tanning bed fusing is not enough to protect you from a fatal shock. Take no chances.

    beds typically have a sail switch that detects the fan running, before it will allow the lamps to start.

    there are a few sites that provide manuals/troubleshooting for the various beds.

    Maybe you should have bought her a Mystic Tan. I hear they are going cheap these days.

    Are you sure its not a safety device so the bed cant be operated with the lid open?
