True Refrigeration Evaporator Fan Motor Assembly 4201940 – Fix Warm Cabinet Fast
A failed evaporator fan motor is the most common cause of a warm cabinet, excessive frost buildup, and uneven temperatures in True commercial refrigerators. In True 700-series reach-in units, the evaporator fan circulates cold air from the evaporator coil throughout the cabinet — when the motor fails, airflow stops, the coil ices over, and product temperatures rise rapidly. ⚡ Common failure point in True-built 700-series commercial refrigerators and freezers. Part 4201940 is the genuine OEM replacement motor assembly that restores proper evaporator airflow and cabinet temperature control immediately.

- No airflow felt inside the cabinet when door is opened
- Evaporator coil completely iced over or frosted solid
- Fan motor humming but blade not spinning (seized bearing)

A fully iced evaporator coil can block the fan blade and mimic a dead motor — always run a manual defrost cycle first and let the coil clear completely before condemning the fan motor. If the motor runs normally after defrost, the root cause is a failed defrost heater or thermostat, not the fan. Replacing the wrong part wastes time and money on a commercial unit.
