The Wacker Neuson 15A 120V DPDT Relay is a genuine OEM electrical relay designed for the HI750 and HI900 series mobile indirect fired air heaters. Sourced directly from Wacker Neuson, this relay meets the exact switching specifications required by the original equipment — ensuring proper control circuit operation right out of the box. It covers a broad range of HI750 and HI900 configurations including diesel, natural gas, and LP-fueled models, as well as skid-mounted and surge brake variants. When your heater's control logic depends on clean, consistent switching, fitting the correct OEM-specified relay is the straightforward choice.
Key Features
- Correct Switching Specification — Rated at 15A and 120V with a double-pole double-throw (DPDT) configuration, matching the original relay's electrical switching behavior exactly.
- Genuine OEM Component — Supplied by Wacker Neuson under part number 5000192467, built to the same design standard as the relay installed at the factory.
- Broad HI750 and HI900 Coverage — Fits diesel, natural gas, LP, DGM, and surge brake variants across both the HI750 and HI900 series, including standard and skid-mounted configurations.
- Heater Control Circuit Integrity — A failed relay can prevent ignition sequencing, blower operation, or fuel valve control from functioning correctly; replacing it restores full heater operation.
- Electrical Safety Compliance — Using a correctly rated OEM relay ensures the control circuit operates within its designed current and voltage limits, reducing the risk of overheating or misfire in the heater's electrical system.
- Direct Drop-In Replacement — Designed to plug into the existing relay socket without modification, making the swap straightforward for service technicians in the field or shop.
A relay is an electrically operated switch that allows a low-power control signal to open or close a higher-current circuit. In indirect fired air heaters like the HI750 and HI900 series, the relay plays a critical role in coordinating control sequences — such as activating the fuel valve, blower motor, or ignition system at the right moment. When a relay fails, it can cause the heater to fail to start, shut down unexpectedly, or lose control of one or more operating functions, making it a key component to inspect and replace during heater troubleshooting.
