Comes with 3 relay components and a 5 amp fuse that repair 99% of all control boards. You must know how to solder with a soldering iron and you must know the correct orientation to install the parts. Capacitors and resistors only go one direction so don't install them backwards b/c they will not work. You need to make sure the relays on your board match the relays in this kit to be compatible for a successful repair.
