Product review (5 stars): Perfect replacement for my 2003 Kenmore (Whirlpool) refrigerator
The only reason I'm reviewing this is to help educate those who are thinking of ordering this kit.  If you are one of them, then your fridge isn't working and you probably realize your relay and overload component is bad.  Many forums help you diagnose the relay/overload unit.  Mine sounded like a rattle when I shook it, had a burnt mark on one lead slot and had little black ceramic pieces falling out of it.  The fridge/freezer wouldn't cool, the compressor wasn't running and the compressor was very hot when touched.

After realizing that my part number is replaced by this kit, I was a bit curious as to how it would all work due to the many parts which are displayed in the picture.  Once I opened the kit, there is a set of directions with photos and all the parts shown in the above picture.  The kit basically comes with four relay/overload setups for four different groups of refrigerators.  You won't use all the parts.  If you are lucky like me and one of the two shown in the picture look identical to the one you are replacing, then you can do a like for like swap ("combo relay").  One is used if there is an EGY80 in the compressor model, while the other is used if there is an EGY90.  These are the ones with the long plastic finger to hold the start capacitor in place.  If yours looks different (no finger), then you will have to do a pieced together rebuild ("discrete") using the remaining parts and jumper cable.  Again, an EGY80 will have you use one overload part, while the EGY90 will have you use the other.  The small relay (black part) is then used for both with the jumper cable.  The exposed rebuild is then covered with the black plastic cover shown in the picture.  If you used one of the combo units, all these other parts are not used at all.

Therefore, you may be lucky and simply have to buy this whole kit to get one of its parts, or you will have to put together a few of the parts in order to replace your old single part.  In the end, the kit should work if your original part number is included in the list.  The directions will help you figure out which part or parts you should use and how to put them all together.

One other thing, I believe my relay might have burned out because I had never cleaned the grate under the fridge for over 7 years.  There sure was a lot of dust in there when I pulled off the front bottom cover.  I vacuumed and blew it all out from the front and back.  The fan next to the compressor needs to be able to draw air through the grate in order to operate the fridge.  When covered with dust, the fridge works much harder.  Now that I cleaned the grate and replaced the relay, the fridge now works better than it did before it broke.  I have to remember to clean it every 6 months.  By the way, my fridge had two hidden papers folded up inside the back of the plastic grill on the front bottom of the fridge.  There are part numbers, electrical diagrams and resistance ratings for key components.  I wish I had known it was there to begin with.
