Personally I have experience working with electricity and knowing if I bought the part required this would be an easy fix. I got my model number and contacted Appliance Parts Pros and placed my order for the new elements, terminal blocks, and for appearance purposes 4 new Drip Pans. Excellent service and quick shipping. I ordered my parts on Sunday and received them on Tuesday.
This was a simple repair that only required a screwdriver to remove the old terminal block from the range hood, wire cutter/strippers too cut and strip the existing wiring going to the terminal blocks and a cigarette light to heat the heat shrinks that are included with your terminal block kit.
This is what I consider to be an easy home repair. If you are not real familiar working with electrical components I suggest you watch the short little videos provided pertaining to how to change the terminal blocks and you will have no problem at all.
