Is this a samsung side by side with just a single evap in the freezer?
If so remove the freezer evap cover and see if it’s iced up.
But before you turn it off, either depending on the model, hold down the top two buttons for self diagnostics for the type with two vertical rows of buttons, or the inner right and outer left for the horizontal button layout, because it could be a fan motor fault or something else.
(I can only give generic advice since model numbers are different here)

If no faults shown, then remove freezer evap cover. If it is iced up, with the power still on, check the voltage across the defrost sensor (normally yellow leads with the sensor either at the evap outlet, or at the bottom of the evap coil). Should be 3+ DC volts if the evap is iced up (voltage decreases with temp, defrost terminates at ~1.9-2V) so if it’s reading ~2v, defrost will never start, and that’s you problem, the sensor). If that’s OK, check thermal fuse and heater for continuity.
But if the heater circuit was open circuit (fuse or heater fault), then the fridge would have chucked a wobbly as it has certain faults it does if the defrost circuit is open circuit, like incorrect temps or flashing display. So it is probably just the coil sensor if it’s not the fan motor
