The Wacker Neuson Control Box is a genuine OEM component designed for the HI 120HD indirect-fired air heater. As a factory-sourced part, it meets the exact electrical and operational specifications of the original unit, ensuring the heater's ignition sequencing, burner control, and safety shutdown functions all operate as intended. This is a direct OEM replacement backed by Wacker Neuson's parts program, making it the straightforward choice when restoring full heater functionality on the HI 120HD.
Key Features
- Genuine OEM Electrical Specification — Sourced directly from Wacker Neuson, this control box matches the exact voltage input, output switching logic, and terminal configuration of the original — no guesswork on compatibility.
- Direct-Fit Replacement for the HI 120HD — Engineered specifically for the HI 120HD indirect-fired air heater; mounts to the existing housing using the original mounting points and wiring harness connectors.
- Restores Full Burner Control Function — A failed or faulty control box can cause the burner to fail to ignite, run erratically, or shut down unexpectedly; replacing it with this OEM unit brings the heater back to full controlled operation.
- Safety-Critical Electrical Compliance — The control box governs safety shutdown sequences on the HI 120HD; using a correctly spec'd OEM replacement ensures those protective functions respond as designed under real jobsite conditions.
- Verified Part Number 5200024745 — Always confirm fitment using the machine's serial number and model designation before ordering to ensure this is the correct control box for your specific HI 120HD unit.
The control box is the central electronic brain of the HI 120HD indirect-fired air heater, managing the ignition sequence, burner operation, and automatic safety shutdowns such as overheat and flame-failure cutoff. Without a properly functioning control box, the heater cannot reliably start, maintain a consistent heat output, or safely shut itself down when a fault is detected. A damaged or failed control box typically presents as a heater that won't ignite, cycles off unexpectedly, or shows fault codes — replacing it with the correct OEM unit is the most direct path to restoring dependable heating performance.
