The Wacker Neuson Control Box is a genuine OEM component designed for the HI 300HD D and HI 200HD D indirect-fired diesel air heaters. Sourced directly from Wacker Neuson, this part carries the same specifications as the unit installed at the factory, ensuring a straight-swap replacement with no guesswork on compatibility. It is confirmed to fit the HI 300HD D and HI 200HD D heater series, making it the correct choice for operators and service technicians maintaining these machines in the field.
Key Features
- Correct Control Circuitry Specs — Genuine OEM construction ensures the control box delivers the exact voltage regulation, switching logic, and output signals required by the HI 300HD D and HI 200HD D heater systems.
- Direct Drop-In Replacement — Matches the original mounting configuration and wiring harness connections of the factory-installed unit for a clean, straightforward installation.
- Confirmed Fitment — Verified for the HI 300HD D and HI 200HD D indirect-fired diesel air heater series; cross-reference part number 5200002663 before ordering.
- Restores Full Heater Operation — A failed or damaged control box can cause erratic ignition cycles, loss of temperature regulation, or complete shutdown; replacing it with this unit returns the heater to full, predictable performance.
- Electrical Safety Compliance — As the primary electrical control component governing ignition and burner operation, using the correct OEM-spec replacement is essential for safe, code-compliant heater operation on the worksite.
The control box is the central electrical brain of the indirect-fired air heater, managing ignition sequencing, burner operation, and temperature regulation. It monitors inputs from sensors throughout the heater and sends commands that keep the combustion cycle running safely and efficiently. When the control box fails or degrades, the heater may refuse to ignite, cycle on and off unpredictably, or shut down entirely — leaving crews without heat in conditions where a reliable heat source is critical.
