Sub-Zero 700TCI-3 Codes 40 & 24, Evaporator Defrost Heater. Took the freezer apart to find the evaporator as a block of ice. Defrosted it and ordered the heater element which tested bad as well as ordering the Defrost Terminator on principal. Today I defrosted it and replaced the parts. Took just over an hour.
Tools needed, 4mm Allen wrench, long Phillips #2 screwdriver, longnose pilers. Maintenance manual is excellent with one exception. The evaporator screws had to be removed to allow the new heater bottom end and the brown wire to go under the evaporator.
