The Wacker Neuson Primary Control is a genuine OEM component designed for the HI 110D Indirect Air Heater and HDR 115 Direct Fired Radiant Heater. As a factory-sourced part, it matches the original electrical and operational specifications required by these heater units — no guesswork on compatibility. This genuine OEM Primary Control is the correct choice when restoring full burner management and ignition sequencing to your Wacker Neuson heater. Confirm your model number against the fitment data before ordering to ensure a direct, correct-fit replacement.
Key Features
- Genuine OEM Burner Control Accuracy — Sourced directly from Wacker Neuson, this Primary Control meets the exact electrical sequencing and safety lockout specifications of the original unit — critical for reliable ignition and flame management in diesel and direct-fired heater applications.
- Direct Drop-In Replacement — Engineered to connect directly to the existing wiring harness and mounting points on compatible Wacker Neuson heater models, restoring the original control circuit without improvisation.
- Fits HI 110D and HDR 115 Heater Series — Confirmed fitment for the HI 110D Indirect Air Heater (Diesel, -20°) and the HDR 115 Direct Fired Radiant Heater — two distinct heating platforms sharing this common control component.
- Restores Full Ignition Sequencing — A failed primary control typically results in a no-start condition, lockout faults, or burner shutdown failures. Replacing it with part 5000186869 brings the ignition and flame-proving circuit back to proper operating condition.
- Fuel System Safety Compliance — The primary control governs fuel valve operation and flame supervision; using a correctly rated OEM part ensures the safety lockout and shutoff functions operate as the heater was designed and tested to perform.
The primary control is the central burner management module in a heater unit — it sequences the ignition process, monitors the flame sensor to confirm successful ignition, and commands the fuel valve to open or close accordingly. If the flame fails to establish or is lost during operation, the primary control triggers a safety lockout to prevent unburned fuel from accumulating. When this component fails, the heater will typically refuse to fire, lock out immediately after ignition attempt, or cycle erratically — symptoms that point directly to the control module rather than the burner or fuel supply itself.
