Danfoss 176F1177 Cooling Fan

For veteran technicians maintaining Danfoss VLT HVAC Drive FC 102, FC 103, FC 202, or FC 302 units, the Danfoss 176F1177 Cooling Fan is the critical OEM replacement part for VFD thermal management. Engineered as a 230VAC 3-phase fan assembly, this 220mm unit is purpose-built to pull unheated air through the heat sink, preventing the IGBT over-temperature faults and DC-link capacitor degradation common in high-demand industrial environments. Operating within a 200V to 240V range, the 176F1177 ensures active cooling for D-frame and larger drives, supporting a volume capacity of 15 to 21 liters. Its IP20 protected enclosure and robust NEMA 1-rated construction provide the reliability needed for HVAC induction motor control and variable speed drive applications in mechanical rooms. Replacing a seized VFD heat sink fan with this genuine Danfoss spare part restores optimal airflow, directly mitigating the risk of costly downtime associated with Alarm 14 or overvoltage trips caused by thermal bias.

• OEM Compatibility: Seamlessly integrates with VLT 5000, 6000, and 8000 series automation drives, ensuring factory-spec fitment and connector alignment.
• Industrial Durability: Features a 220mm diameter blade designed for high-static pressure, maintaining active cooling even in dust-prone environments.
• Electrical Efficiency: Optimized for 230V 3-phase power supply, delivering consistent CFM without excessive noise or vibration.
• Ease of Service: Direct-swap assembly with a pre-wired fan cable connector and rubber grommet for simplified field replacement.

Which Danfoss drive models are compatible with the 176F1177?
This VFD cooling fan is specifically designed for the VLT FC series (FC 102, 103, 202, 302) and legacy VLT 6000 series, particularly within the 75–125 HP range across D1h–D8h frames.

Does this fan resolve Alarm 13 or Alarm 14 on my drive?
While Alarm 14 often indicates ground faults, an overheating heat sink due to a failed 176F1177 fan can cause internal component bias. Replacing a seized fan is the standard first step if the drive trips under load due to temperature spikes.

What are the voltage requirements for this assembly?
The unit is rated for 200V to 240VAC. Attempting to run this 230V fan assembly on a 460V control circuit without the appropriate internal step-down will result in immediate motor failure.
