While troubleshooting my 4 year old GE french door refrigerator, Model GFE28GMKJES I am trying to understand the values displayed while in diagnostic mode. Maybe they are described in the service manual, but I can't seem to find that.

For example:

• Test 0029 "Ambient Temp Test"
  displays 65 in left(FZ) display which seems like plausible ambient air temp.
  But the right display(FF) displays a sequence of numbers: 61,25,43. What do those second numbers mean?
  
  
• Test 0040 "Humidity Sensor Test"
  FZ: 41 (a plausible value for humidity)
  FF: 60,75,41
  
  
• Test 0037 "FF Door Ice Cabinet Thermistor Test"
  FZ: 28 and dropping as the ice making cabinet cools after I was messing with it
  FF: 52, 25, 97, 84, 56, 43, 70, 29, 15, 2, 88, 74, and it keeps going. with occasional pauses.
  

Thanks,
Jeff
