The Wacker Neuson Temperature Sender is a genuine OEM component designed for the HI 770 XHD indirect-fired air heater series, including Arctic Bear XHD and HI770XHD models. As a direct OEM replacement, this sender is sourced and manufactured to the exact specifications of the original part, ensuring it integrates correctly with the heater's temperature monitoring and control system. Compatible across multiple HI 770 XHD configurations — including 2x12, 1x16, and 1x20 duct layouts as well as Extra Heavy Duty variants — this is the correct part to reach for when servicing these diesel-fired indirect heaters.
Key Features
- Calibrated OEM Signal Output — Manufactured to the exact resistance and response curve specifications of the original sender, ensuring accurate temperature readings within the HI 770 XHD control circuit.
- Drop-In Replacement — Matches the original sender's thread pitch, connector type, and mounting location for a straightforward swap during scheduled service or fault repair.
- Broad HI 770 XHD Coverage — Fits Arctic Bear XHD and HI770XHD series heaters across 2x12, 1x16, 1x20, and Extra Heavy Duty configurations.
- Protects Heater Operation — A correctly functioning temperature sender keeps the heater's control system informed of actual operating temps, preventing thermal runaway or nuisance shutdowns caused by a failed or drifted sensor.
- Fuel System Safety Relevance — In a diesel-fired indirect heater, accurate temperature sensing is critical to safe combustion control; a faulty sender can cause the unit to run outside safe operating limits.
The temperature sender monitors the heat exchanger or airflow temperature within the indirect-fired heater and transmits a signal to the control board, allowing the unit to regulate burner output and maintain the set temperature. When the sender fails or drifts out of calibration, the heater may shut down unexpectedly, fail to reach set temperature, or — in a worst case — run without proper thermal feedback. Replacing a worn or faulty sender with a genuine Wacker Neuson 5000173571 restores accurate temperature control and keeps the HI 770 XHD operating safely and efficiently on the jobsite.
