Faulty PWM?

If you sent it to FIRST for diagnosis and repair, it is no wonder they just sent it back to you. The Victor Speed Controllers (and Spike Relays, and RC, and OI, etc.) are all Innovation First, Inc. products. As noted in Section 5.4.3 of the manual, all IFI products need to be sent back to them - not FIRST - for replacement or repair.

Historically, IFI does a pretty good job of quality control. Occasionally there have been a very few bad units that have slipped through. But many times the "bad units" have been damaged after leaving IFI (during shipping, packing into the kits, etc.) or by the occasional fat-fingered-software-geek-pretending-to-be-a-mechanical-designer that accidently shoves a screwdriver into the turning fan blades and then quickly puts the broken unit down on the table and walks away while innocently asking "hey, who broke the Victor?" (don't ask me how I know about this )

Anyway, back to the original problem. Upon occasion, we noticed that the Victors will sometimes (not every time, or even the majority of times, just occasionally) show orange if the PWM cable is inserted backwards into the plug. We found this out when we were using some older PWM cables that had smaller plastic ends that were not keyed, and fairly easy to insert backwards by mistake. I know this seems like a simple, basic item, but check to be sure that the PWM cables are installed correctly and completely seated on the pins.
