O4-R1211 - Genuine OEM All Temp Refrigeration Evaporator Coil Motor, 3.3" Dia. 1400 RPM, 115V

O4-R1211 – Genuine OEM All Temp Refrigeration Evaporator Coil Motor (3.3" Dia, 1400 RPM, 115V)

The O4-R1211 is a Genuine OEM refrigeration evaporator coil motor designed for commercial and residential refrigeration systems. Built with a 3.3-inch frame, 1400 RPM speed, and 115V operation, this motor is engineered to deliver consistent airflow across evaporator coils, ensuring stable cooling performance in refrigeration units.

This type of evaporator fan motor is commonly used in walk-in coolers, display cases, reach-in refrigerators, and other all-temperature refrigeration systems where reliable air circulation is critical for maintaining safe food storage temperatures.

Available across Canada from Appliance Kingdom with fast nationwide shipping for technicians, property managers, and commercial refrigeration service providers.

Function & Importance of the O4-R1211 Evaporator Coil Motor

The evaporator coil motor is responsible for driving the fan that moves air across the evaporator coil. This airflow is what allows the refrigeration system to absorb heat from inside the cabinet and maintain consistent cold temperatures.

In refrigeration systems like walk-in coolers and display units, this motor ensures:

• Continuous airflow across the evaporator coil

• Even temperature distribution inside the cabinet

• Proper heat exchange for efficient cooling

• Prevention of ice buildup on coils (in normal operating conditions)

• Stable performance of the refrigeration cycle

Because it runs continuously in many applications, OEM-grade construction is essential for durability, thermal stability, and long-term reliability.

What Happens When This Motor Fails?

A failing evaporator coil motor can quickly affect refrigeration performance. Common failure outcomes include:

• Weak or no airflow across evaporator coil

• Warm spots inside cooler or refrigerator

• Rising internal temperatures in commercial units

• Ice accumulation on evaporator coil

• Compressor running longer than normal

• Product spoilage due to inconsistent cooling

If the motor stops or slows significantly, the refrigeration system cannot properly absorb heat, leading to rapid loss of cooling efficiency.

Common Symptoms Indicating Replacement

You may need to replace the O4-R1211 evaporator coil motor if you notice:

• Fan inside evaporator section not spinning

• Loud grinding, humming, or rattling noises

• Reduced cooling in refrigerator or walk-in cooler

• Frost or ice buildup on evaporator coil

• Hot compressor with poor cabinet cooling

• Airflow imbalance inside refrigeration cabinet

Replacing a worn or failed evaporator motor often restores proper airflow and stabilizes temperature performance.

Compatibility Guidance

This O4-R1211 motor is designed for refrigeration evaporator coil applications (3.3” frame, 115V systems, ~1400 RPM class) commonly found in commercial cooling equipment.

Before ordering:

• Always verify motor frame size (3.3")

• Confirm voltage requirement (115V)

• Match RPM range and mounting configuration

• Check shaft and bracket style on your existing motor

If you are unsure, confirm your unit’s model plate or consult a refrigeration technician before installation.
