The Wacker Neuson Ionization Electrode is a genuine OEM component designed for the HI 400HD G Indirect Air Heater. Sourced directly from Wacker Neuson, this part meets the exact electrical and dimensional specifications required for proper combustion sensing in the HI 400HD G. Replacing a failed or degraded ionization electrode with the correct OEM part restores reliable ignition monitoring and keeps the heater operating as intended.
Key Features
- Correct Signal Output: — Genuine OEM construction ensures the electrode delivers the precise ionization signal the heater's control circuit expects — no guesswork on resistance or tip geometry.
- Direct Drop-In Replacement: — Engineered to the original mounting specification, this electrode seats and connects exactly as the factory unit does, with no reworking of brackets or wiring.
- Confirmed Fitment: — Verified for the HI 400HD G Indirect Air Heater, so you can order with confidence that this is the right part for your machine.
- Combustion Stability: — A properly functioning ionization electrode gives the control board a clean flame-detection signal, preventing nuisance lockouts and ensuring consistent heat output on the job.
- Combustion Safety Compliance: — The ionization electrode is a critical flame-monitoring component. Using the correct OEM part ensures the heater's safety shutdown circuit responds accurately to flame loss, protecting both the equipment and the operator.
The ionization electrode is a key part of the burner control system in an indirect air heater. It sits within the combustion chamber and generates a small electrical signal in the presence of a flame — the control board reads this signal to confirm that combustion is occurring. If the electrode is worn, fouled, or out of position, the control board cannot detect the flame reliably, causing the heater to lock out or fail to start. Replacing a degraded electrode restores clean flame detection and stable, uninterrupted heater operation.
