The other day I went to a yard sale and there was a nice commercial fan. I bought it for $2. Only one of the 3 speeds worked but so what- I figured I could use it in the shop. Anyway, after 2 hours the fan shorted out. Its got a cheap-o plastic switch which I believe was what caused the issue. My plan is to just wire it up to a single throw switch so it will run on high. Only problem is that there are 4 wires coming out of the motor: white, black, red, and blue. According to the diagram black is high speed, white is common, red is medium, and blue is low. I wired up black and white. Nothing. So either there's some sort of fused link or I've incorrectly wired it. Question is since white is common, could I connect either the red or blue wire to the white wire? The motor has independent windngs for each speed so I'm guessing that the high speed is fried.
Sorry this sounds stupid but I figured some of you geniuses would possibly know.
