If the original MAIN BOARD number is: 6971JB1292Y...
You'll need to replace it with the revised MAIN BOARD # EBR58010501
Additionally---you'll need to pull the freezer & refrigerator THERMISTORS from the liner insulation (imbedded in foam) and then attach the THERMISTOR to their "cages".
Doing so---will end *overcooling* in the freezer compartment.
This was a problem found in models with SERIAL NUMBERS up to
812MRxxxx (December 2008 & older)
