The Wacker Neuson Control Box is a genuine OEM component designed for the HI110D, HI110HD D, HI200D, HI200HD D, and HI300D series indirect-fired diesel air heaters. As a factory-sourced replacement, this control box is built to the exact electrical specifications of the original unit, ensuring correct operation across all supported HI-series models. Fitment covers multiple configurations within the HI110D, HI200D, and HI300D families, making this a versatile service part for fleet operators and rental companies running Wacker Neuson indirect heaters.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact output and switching tolerances required by Wacker Neuson HI-series indirect diesel heaters, ensuring correct ignition sequencing and burner control.
- Direct-Fit Replacement — Matches the original mounting footprint and wiring harness connections, allowing installation without modification to existing brackets or connectors.
- Broad HI-Series Compatibility — Fits HI110D, HI110HD D, HI200D, HI200HD D, HI300D, and HI300HDD models across multiple serial number ranges, covering a wide portion of the indirect diesel heater lineup.
- Restores Full Heater Control Function — A failed or faulty control box can prevent ignition, cause erratic burner cycling, or disable safety shutdowns entirely; replacing it with a genuine unit restores dependable heat output and correct operating behavior.
- Safety-Critical Electrical Component — The control box governs ignition, fuel valve operation, and overheat protection circuits; using an OEM-verified replacement ensures these safety functions operate within designed parameters.
The control box is the central electronic brain of an indirect-fired diesel air heater. It manages the ignition sequence, regulates the fuel solenoid valve, monitors flame detection, and activates safety shutoffs in the event of overtemperature or ignition failure. When the control box fails or degrades, the heater may refuse to start, shut down unexpectedly mid-cycle, or — in more serious cases — bypass protective circuits that prevent unsafe operation. Replacing a worn or failed control box with a genuine Wacker Neuson 5000186770 unit restores full electronic oversight of the combustion process, keeping the heater operating safely and efficiently in demanding cold-weather job conditions.
