We have replaced the 3 speed fan switch and now the fan doesn't work at all

Brand and model would help. Did you use an OEM switch identical to the one that was bad?

No I used a switch from home depot, which was identically marked as the oem and wired it exactly as the old one. L1 was red-2 was black-3 was blue- 4 was black. I do not know the make of the fan on the pull chain it said SMC

No I used a switch from home depot, which was identically marked as the oem and I wired it exactly as the old one. L red--1 black--2 blue--3 black then plugged it back in to the connector, turned it on and nothing happened. I do not know the make of the fan but the pull chain says SMC.

I used a switch from home depot with the same markings and wired it the same. L--red, 1--black, 2--blue, 3--black, plugged in the connector, turned it on and nothing happened. I do not know the make of the fan but on the pull chain it says SMC. Thanks

You probably don't have the correct replacement switch. Use the old switch, match it up on CeilingFanParts.com Home

And use these instructions:
