Outdoor half (compressor and fan) of central AC wouldn't shut off, just ran continuously.Logic says the contactor is stuck on.This item is a pretty generic replacement contactor for the average AC and installs in 15 minutes with just a screwdriver for anybody with enough knowhow to turn the power to the outside unit off.If you don't know how to turn the power to the outside unit off., though, get somebody else to install it.
