Replacing electrical outlets results in power loss???

[Briana W.]

Hi all, I was helping my mom replace outlets in her 37 year old home and 4 were replaced with no difficulty then suddenly a bunch of appliances in the kitchen went out including the fridge. The fuse box says everything is a go and the GFIC's are all ok. Any ideas? Maybe replace specific fuses? Also, the outlets with 4 wires are easy enough to replace but others have 6 wires. Some have 3 white, 3 black. Others have 2 white, 2 black, 2 red. Any advice is appreciated! Thanks!
