That’s most likely going to be the defrost heater 5303918255 or the adaptive defrost control 5303918476,
You can test the defrost heater circuit from the adaptive defrost control with a meter. You’ll need to access the control with the fridge powered off, look for light blue, blue, and brown wires. If you’ve got a plug with all the wires going to the ADC on there just disconnect it, if each terminal just has an individual connector disconnect those 3 wires. You’ll be testing blue to brown and light blue to brown, looking for about 30Ω on each. If those are good then you’re ADC or adaptive defrost control is bad.
It looks like the ADC has been discontinued without a substitute or replacement part listed, but the defrost heater is still available.
