I have two GE box fans, vintage ones, and I noticed on the sticker it has a four digit P.S. No.
Do anyone know what P.S. No. means? Is this date code? I know on GE electronics, they used a four digit date code usually. I wonder if the fans were the same way. But not all GE fans, have that number on it.
The only thing I know of P.S. meaning is packing slip.
