The Wacker Neuson Capacitor is a genuine OEM component designed for the HI1000 and HI1000DGM Indirect Air Heater series. As a direct-replacement electrical component sourced from Wacker Neuson, part number delivers the correct capacitance rating your heater's motor circuit depends on for reliable cold-weather operation. This capacitor fits across the full HI1000 family, including Diesel, Gas, and DGM Electric Break and Surge Brake configurations. Ordering the OEM part ensures your heater is back up and running to its original operating spec without guesswork.
Key Features
- Correct Capacitance Rating — Matched to the HI1000 motor circuit's exact electrical specification, ensuring the motor starts and runs at full output rather than struggling or failing to energize.
- Genuine OEM Part — Sourced directly from Wacker Neuson, so you get the same component originally installed on the heater — no substitutions, no compatibility concerns.
- Broad HI1000 Family Coverage — Fits HI1000 Diesel w/Tank, Diesel, Gas, and HI1000DGM Electric Break and Surge Brake indirect air heater variants.
- Drop-In Electrical Replacement — Designed to connect directly to the existing motor wiring harness, making swap-out straightforward for any technician familiar with the HI1000 platform.
- Electrical Safety Compliance — Using the correct OEM-rated capacitor protects the motor windings from voltage imbalance caused by an out-of-spec or failed unit — critical on a fuel-burning heater operating in enclosed or temporary structures.
A capacitor in an indirect air heater provides the phase-shift voltage needed to start and sustain the motor that drives the combustion air blower. Without a functioning capacitor, the blower motor cannot reach operating speed — causing the heater to fail to ignite, short-cycle, or trip on thermal overload. A degraded capacitor can also cause the motor to draw excessive current, accelerating winding wear and potentially causing motor failure if left unaddressed.
