Final answer:

Excess ice formation on a low-temperature evaporator can be caused by various issues such as a defective evaporator fan motor, defrost heater, or insufficient duration of defrost cycles.


Explanation:

Ice formation on a low-temperature evaporator can be caused by several issues:

  1. The evaporator fan motor being defective can result in inadequate airflow, leading to ice buildup.
  2. A defective defrost heater can prevent proper melting of ice during defrost cycles, contributing to excess ice formation.
  3. If the unit is not staying in defrost long enough, ice accumulation can occur as the system is unable to remove the ice effectively.

Therefore, all of the options presented could be potential problems causing excess ice formation on a low-temperature evaporator.
