The Wacker Neuson Terminal Board is a genuine OEM component designed for the HI-series indirect-fired air heaters and HDR-series direct-fired radiant heaters. As a direct factory replacement, this terminal board matches the original electrical layout and connector positions found in models including the HI 110D, HI 200D, HI 300D, HI 400HD D, HI 90, HI 120, HDR 115, HDR 155, and related HD variants. Sourced directly from Wacker Neuson, part meets the same manufacturing standards as the board it replaces. Keeping this component in proper working order is essential to safe, consistent heater operation on cold-weather jobsites.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the original circuit layout and connector specification, ensuring correct voltage distribution across all heater control circuits.
- Drop-In Replacement — Mounting points, terminal positions, and wiring harness connectors align directly with the original board, so installation follows the factory service procedure without modification.
- Broad HI & HDR Series Coverage — Confirmed fitment across the HI 35, HI 90, HI 110D, HI 120, HI 200D, HI 300D, HI 400HD D, HDR 45, HDR 115, HDR 155, HD 50, HD 70, and associated HD variants.
- Restores Full Heater Control Function — A failed terminal board can cause intermittent ignition, loss of burner control, or complete heater shutdown; replacing it with a correct OEM board brings the unit back to full operational status.
- Electrical Safety Compliance — Using a genuine OEM board ensures the heater's control circuitry operates within its designed current and insulation ratings — critical for fuel-burning equipment in enclosed or semi-enclosed work areas.
The terminal board is the central wiring hub of the heater's control system, routing electrical signals between the thermostat, ignition components, fuel system, and safety cutoffs. When the board is damaged or develops a failed connection, the heater may refuse to ignite, cycle erratically, or trip safety shutoffs without a clear cause. Replacing a worn or faulty terminal board with the correct OEM part restores proper signal routing throughout the unit, allowing every downstream component to receive the input it needs to function as intended.
