Wacker Neuson 5100050033 Wire (Ionization, Hi 400)

The Wacker Neuson Wire (Ionization, Hi 400) is a genuine OEM component designed for the HI 400HD G Indirect Air Heater. Sourced directly from Wacker Neuson, this ionization wire meets the original electrical specifications required for reliable ignition sensing in the HI 400HD G heating system. Confirming your model number against part number before ordering ensures a direct, hassle-free installation.

Key Features

• OEM-Correct Electrical Specification — Manufactured to the original resistance and insulation ratings required for accurate ionization signal detection in indirect air heaters.
• Direct Drop-In Replacement — Engineered to the same connector and wire length as the original, allowing straightforward installation without modification to existing harness routing.
• Confirmed Fitment for HI 400HD G — Verified fit for the Wacker Neuson HI 400HD G Indirect Air Heater, so you can order with confidence.
• Consistent Ignition Sensing — A properly functioning ionization wire ensures the heater's control system can detect and confirm a stable flame, maintaining steady heat output on the worksite.
• Electrical Safety Integrity — As a critical component in the heater's flame-sensing circuit, using a genuine OEM wire helps maintain correct low-voltage signal behavior and reduces the risk of nuisance shutdowns or undetected ignition faults.

The ionization wire is a key part of an indirect air heater's flame-detection circuit. It carries a small electrical signal that allows the control board to confirm whether a flame is present inside the combustion chamber — if the flame is detected, the heater continues to run; if not, the system shuts down safely. When this wire degrades, corrodes, or breaks, the heater may fail to start, shut off unexpectedly, or produce fault codes, even when the burner itself is functioning correctly. Replacing a worn ionization wire restores accurate flame sensing and keeps the heating system operating as intended.
