No that your unit is not defrosting, may have shorted the defrost control again.You should get a ohm meter. This will help checking the heater and the defrost sensor.

It doesn't really look normal. I just observed that the black bars on the bottom, under the evap actually heats up. Not to sure if that's supposed to happen or not, but yah.

Thanks again for helping

Don't this thang have a heater? In that case it is gonna need a old school terminator.
Thermistor and terminator are 2 diff animals on 2 dif circuits.

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)

I checked with appliancepartspros and according to them the part number 401c acts as a termination thermostat. (me being Jdizzle lol)
Looks to me like the very bottom of the coils is the heater Heater/shield assembly Is what I believe it is called maybe Johnny will enlighten us.

Im almost sure the heater is working, i accidentally put a plastic bag in the freezer, with some beef. and it was touching the heater, and it melted the plastic.



The black lines didn't burn the plastic though, it was only the part circled in red. The burnt marks are from the plastic bag.

my serial number starts with 710MRM, manufacture date 2007. so does this mean i have to change the mother board and change the THERMISTORS?
