The Wacker Neuson 5000183968 Transformer is a genuine OEM component designed for the HI-series indirect-fired diesel air heaters, including the HI 400HD D, HI 300HD D, HI 200HD D, HI 200D, HI 110HD D, HI 110D, HI 300D, and HDR 155 Direct Fired Radiant Heater. Sourced directly from Wacker Neuson, this transformer meets the exact electrical specifications of the original factory-installed unit. It is a direct-fit replacement that installs into the heater's ignition and control circuit without modification. Confirm your machine model number before ordering to ensure correct application.
Key Features
- Correct Output Specification — Genuine OEM construction ensures the transformer delivers the precise voltage and current output required by the HI-series ignition and control system — no guesswork on electrical compatibility.
- Direct-Fit Installation — Engineered to match the original mounting points and wiring connections of the HI-series heater chassis, allowing straightforward swap-out during service.
- Broad HI-Series Coverage — Compatible with multiple Wacker Neuson indirect and direct-fired diesel heater models, including the HI 400HD D, HI 300HD D, HI 200HD D, HI 200D, HI 110HD D, HI 110D, HI 300D, and HDR 155.
- Sustained Ignition Performance — A correctly functioning transformer maintains stable, consistent spark energy at the burner igniter — a failed or degraded transformer typically causes no-start or unreliable ignition in cold-weather conditions.
- Genuine Wacker Neuson OEM Part — Backed by Wacker Neuson's parts program, part number 5000183968 is the factory-authorized replacement, giving you confidence in long-term electrical integrity across seasonal heating operations.
The transformer in a diesel indirect-fired air heater steps up voltage from the heater's control circuit to generate the high-voltage spark needed to ignite the fuel-and-air mixture at the burner assembly. It is a core component of the ignition system — without a properly functioning transformer, the burner cannot reliably light, leaving the heater unable to produce heat output. When a transformer fails or degrades, symptoms typically include intermittent ignition, a complete no-start condition at the burner, or fault codes on the heater's control panel, all of which halt operation in applications where continuous heating is critical, such as cold-weather concrete curing, ground thawing, or enclosed workspace heating.
