Hello and thank you for the opportunity to help you.
Your defrost heater has most likely failed. This sits under the evaporator in the freezer behind the lower rear panel. It should read around 27 ohms resistance. The new part is a double coil heater instead of a single coil heater. Instructions are included. This is a VERY common part to fail. Part number WR51X10101. You'll see a blue and a pink wire attached to it.
If defrost does not occur, frost accumulates and suffocates proper air flow throughout your entire refrigerator. The filter reset light just refers to your water filter needing replaced.
