Wacker Neuson 5200000576 VFD Module Complete

The Wacker Neuson VFD Module Complete is a genuine OEM component designed for HI750GM and HI900DGM series indirect-fired air heaters. Sourced directly from Wacker Neuson, this assembly carries the same part number and specification as the original unit installed at the factory. Compatible models include the HI750GM, HI750GM SB, HI750GM HD Mobile, HI900DGM, and HI900DGM with Surge Brake configurations — making it a verified fit across the full HI750GM and HI900DGM heater families. When your variable frequency drive module fails, replacing it with the correct OEM assembly restores full burner and airflow control performance without guesswork.

Key Features

• OEM-Spec Drive Control: — Matched to the original variable frequency drive output ratings for precise burner motor speed regulation in Wacker Neuson indirect heaters.
• Complete Assembly Replacement: — Supplied as a complete module, enabling a direct swap into the existing mounting position without sourcing individual components separately.
• Broad HI-Series Fitment: — Confirmed fit across HI750GM, HI750GM SB, HI750GM HD Mobile, HI900DGM, and HI900DGM Surge Brake indirect-fired air heater models.
• Restores Full Heating Output: — A failed VFD module causes loss of motor speed control and reduced or erratic heat output; this replacement brings the heater back to full operational capacity.
• Electrical Safety Compliance: — As a primary drive and control component in a fuel-burning heater, using a genuine OEM module ensures correct voltage handling and protects connected electrical systems from mis-matched drive signals.

The VFD (Variable Frequency Drive) module controls the speed of the burner blower motor in an indirect-fired air heater, regulating airflow and combustion to deliver consistent, controlled heat output. By varying the motor's operating frequency, the module allows the heater to modulate its output rather than simply switching on and off — improving efficiency and temperature stability on the jobsite. When the VFD module degrades or fails, the blower motor may run erratically, stall, or stop entirely, resulting in loss of heat output or a heater that fails to start.
