This Part Fixes These Problems

Refrigerator Not Cooling

Fridge or freezer too warm, food not staying cold — failed evaporator fan stops cold air circulation throughout the compartments.

Loud Buzzing or Grinding Noise

Worn motor bearings cause abnormal rattling, buzzing, or squealing sounds coming from inside the freezer section.

Excessive Frost Buildup

Blocked airflow from a seized fan motor leads to frost accumulation on evaporator coils and freezer walls.

Fan Not Running

Motor fails to spin even when the door switch is manually depressed, indicating a burned-out or seized motor winding.

💡 Pro Tip: Is Your Evaporator Fan Motor Failing?

Your part is likely the culprit if you notice any of the following:

⚠️ Refrigerator or freezer not cold enough / food spoiling faster than usual

⚠️ Unusual buzzing, grinding, or rattling noise coming from the back of the freezer

⚠️ Excessive frost or ice buildup on the evaporator coils or freezer walls

⚠️ Fan blade visible but not spinning when freezer door is opened and door switch is depressed

🔍 Diagnostic tip: Open the freezer, press the door switch manually to override it, and listen — if the fan motor doesn't run or runs intermittently, the motor is faulty. Always unplug the refrigerator before beginning any repair.

Questions & Answers

Will this W11578030 motor fit my WRF757SDHZ04 refrigerator?
Answered by Support Team  ·  Aug 12, 2025
Yes — the W11578030 is a direct fit for the WRF757SDHZ04 and all WRF757SDHZ/SDHV03-04 variants. Just confirm your model tag inside the fridge door matches this list before ordering.
What are the electrical specs of this evaporator fan motor?
Answered by Support Team  ·  Nov 3, 2024
The W11578030 runs on DC 12V, draws 2.5W, and operates at 2750 RPM. These specs are identical to the original Whirlpool OEM unit and its predecessor W11402610.
Does this part include the fan blade?
Answered by Support Team  ·  Feb 20, 2025
Our replacement motor ships as the motor only, without a fan blade. In most cases you can reuse the original fan blade from your old motor — simply pull it off the old shaft and press it onto the new one. If the original blade is cracked or damaged, order a replacement blade separately.
My refrigerator runs but doesn't cool — could this motor be the problem?
Answered by Support Team  ·  Apr 17, 2024
Absolutely. The evaporator fan motor is responsible for circulating cold air from the freezer coils into the refrigerator. If the motor fails, air stops moving and both compartments warm up. Open the freezer, press the door switch manually, and listen — if no fan noise is heard, replace the motor.
Is this motor compatible with KitchenAid KRFF577KPS01?
Answered by Support Team  ·  Jan 9, 2026
Yes, the W11578030 is confirmed compatible with the KitchenAid KRFF577KPS01 as well as the KRFF577KBS01. It also fits KRFF507H series models (HBS03/04, HPS03/04, HWH03). Always verify your full model number before purchase.
