What 35 C 00
actually means.
On Designer models, 35 C 00 says the DC condenser fan circuit is open. That fan pulls air across the condenser so the compressor can shed heat; without it the system runs hot and the freezer can lose ground, especially in a warm kitchen or garage.

What to do when 35 C 00 shows on the freezerKind of codeFans and airflow
A fan that should have been turning is slow, stalled or stopped. Inside the cabinet, the fan pushes cold air off the coil and around the food; at the base or the back, a second fan cools the condenser so the compressor does not overheat. Ice rubbing on a blade, a package pushed against a vent and lint wrapped around a shaft are cleared before a motor is ordered.

What not to do
35 C 00 is not the fan inside the freezer; the evaporator fans use zone numbers in place of the C. It also does not mean the compressor has failed, though a stopped condenser fan will make it overheat.
