The Wacker Neuson Rectifier Complete is a genuine OEM component designed for the Arctic Bear XHD and HI 770 XHD series indirect air heaters. Sourced directly from Wacker Neuson, this rectifier complete carries the same part number and specification as the original unit installed at the factory. It is confirmed to fit multiple HI 770 XHD configurations, including diesel models across single- and dual-outlet variants, as well as Extra Heavy Duty Air Heater builds. When your existing rectifier fails, replacing it with the correct OEM part ensures the heater's electrical system returns to proper operating condition without guesswork.
Key Features
- Correct Electrical Output Spec — Genuine OEM construction ensures this rectifier delivers the precise voltage conversion required by the HI 770 XHD heater's control circuit, matching the original component exactly.
- Direct Plug-In Replacement — Engineered to the same connector and housing dimensions as the factory unit, so installation aligns with the existing wiring harness without alteration.
- Broad HI 770 XHD and Arctic Bear XHD Coverage — Verified fitment across Arctic Bear XHD, HI 770 XHD diesel 2x12, 1x16, and 1x20 configurations, plus Extra Heavy Duty Air Heater models.
- Restores Consistent Ignition and Burner Control — A functioning rectifier maintains stable DC power to the heater's control board; a failed unit can cause erratic ignition, burner lockout, or complete heater shutdown in cold-weather operations.
- Electrical Safety Assurance — As a critical component in the heater's power conversion circuit, using a genuine OEM rectifier eliminates the risk of under-spec components that could introduce voltage irregularities or damage downstream electronics.
- Genuine Wacker Neuson Part — Supplied under part number 5200011731 with full Wacker Neuson OEM traceability, giving you confidence that you are installing the same component the machine was built with.
A rectifier converts alternating current (AC) produced by the heater's generator or power source into the direct current (DC) needed to operate the control board, ignition system, and safety circuits of an indirect air heater. Without a properly functioning rectifier, the heater cannot maintain the stable electrical supply its burner and fan controls depend on, which can result in failed startups, mid-cycle shutdowns, or erratic operation — especially problematic in demanding cold-weather jobsite conditions. Replacing a failed or degraded rectifier complete with the correct OEM unit is one of the most direct ways to restore full, dependable heater performance.
