Product review (5 stars): Same as the Original - WORKED FOR ME
Used on Maytag FWW2558VEW4 refirigerator (5 years old).  The fridge section was getting warm while the freezer section was getting extra cold.  I keep  thermometers in both sections at all times and check periodically.  I did some research on the web and a little troubleshooting and figured (guessed) the defrost cycle was no longer functioning.  I searched for the board online and every place wanted $200.00 and to have a repair person would have cost half the price to replace it; so I came across this little puppy for $100.00 and it WORKED!!!!  Praise the Lord!!

The sticker on the back of the board has Whirlpool on the back like the original Jazz Board.  Good deal!!
