The Wacker Neuson Terminal Board is a genuine OEM component designed for the HI series indirect-fired air heaters, including the HI200D, HI200HD D, HI300D, HI300HD D, HI400HD G, HI400HD D, HD50, HD70, HI35, HI90, HI90HD, HI120, and HI120HD models. As a factory-sourced part, it meets the exact electrical specifications required to maintain proper heater operation and control system integrity. This terminal board is the correct replacement when the original has failed due to corrosion, heat fatigue, or electrical fault. Confirm your machine's model number before ordering to ensure a direct fit.
Key Features
- Genuine OEM Electrical Specification — Manufactured to Wacker Neuson's exact conductor rating and terminal spacing requirements, ensuring correct signal routing and connection integrity across the heater's control circuit.
- Drop-In Replacement — Matches the original mounting footprint and terminal layout of the 5000183967 board, allowing direct installation without modification to wiring harnesses or brackets.
- Broad HI Series Compatibility — Fits a wide range of Wacker Neuson indirect-fired air heaters including the HI200D, HI300HD D, HI400HD G and D, HI90, HI120, HD50, HD70, and more.
- Sustained Heater Control Performance — A correctly functioning terminal board maintains stable electrical connections between the heater's ignition, fuel, and safety circuits — preventing erratic cycling, ignition failure, or unplanned shutdowns on the jobsite.
- Fuel System and Ignition Safety — In indirect-fired heaters, the terminal board connects critical safety and fuel control circuits; a faulty board can cause unsafe operating conditions, making like-for-like OEM replacement the correct course of action.
The terminal board serves as the central wiring junction point within the heater's electrical control system, providing secure, organized connections between the ignition components, fuel solenoid, thermostat, and safety switches. It ensures each circuit receives a clean, stable connection — keeping the heater firing consistently and shutting down safely when required. When a terminal board corrodes, cracks, or develops a failed connection, the result is typically intermittent ignition, loss of flame, or a heater that will not start at all.
