The Wacker Neuson 5000183982 Electrode is a genuine OEM component designed for Wacker Neuson indirect air heaters and direct fired radiant heaters, including the HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HI 90, HI 90HD, HI 120, HI 120HD, HDR 155, HDR 45, and HD 70 series. As a direct OEM replacement, the part is manufactured to the same specification as the original part, ensuring correct positioning, gap, and ignition performance in the heater's burner assembly. This electrode covers a broad range of Wacker Neuson diesel and direct-fired heater models, making it a reliable service item to keep on hand for seasonal heater maintenance or emergency repair.
Key Features
- Genuine OEM Ignition Specification — Manufactured to the exact tip geometry and gap tolerance required for reliable spark ignition in Wacker Neuson heater burner assemblies.
- Direct Drop-In Replacement — Mounts to the original electrode bracket and connects to the ignition lead without modification, restoring the burner circuit to its original configuration.
- Broad Heater Family Coverage — Fits HI 90, HI 120, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HDR 45, HDR 155, and HD 70 series heaters in a single part number.
- Consistent Ignition Performance — A correctly functioning electrode produces a strong, well-positioned spark every cycle; a worn or fouled electrode leads to failed startups, lockouts, and unreliable heat output on the jobsite.
- Fuel System Safety Relevance — Because the electrode initiates combustion in a diesel-fired burner, correct spark timing and gap are critical to safe, complete ignition and prevention of unburned fuel accumulation.
The electrode is the ignition component in the heater's burner assembly, generating the high-voltage spark that ignites the diesel fuel-air mixture at startup. It must be precisely positioned relative to the burner nozzle so that every ignition attempt produces a clean, complete flame — if the electrode tip is cracked, corroded, or the gap has shifted, the heater's control board will detect a failed ignition event and shut the unit down as a safety measure. Over time, exposure to combustion heat and carbon deposits causes electrode deterioration, making it one of the most common service parts on diesel indirect and direct-fired heaters.
