Troubleshooting
-
Cover doesn’t fit: Verify motor frame size, dimensions and accessory mounting—older motors with large capacitors or extra enclosures may require a different cover.
-
Poor clearance or overheating: Ensure ventilation ports are clear and the cover isn’t too tightly enclosed restricting airflow.
-
Cover cracks or warps: Replace if significant UV or heat damage is visible to avoid motor exposure.
Maintenance Tip
Inspect the motor cover each season for signs of damage or wear, clean out any debris from inside the cover and ensure proper airflow. Replacing older or cracked covers with the R221016 helps maintain motor protection and prolongs equipment lifespan.
