Wacker Neuson 5100050031 Wire (White, Burner Thermostat Hi 400)

The Wacker Neuson Wire (White, Burner Thermostat Hi 400) is a genuine OEM component designed for the HI 400HD G Indirect Air Heater. Sourced directly through Wacker Neuson's authorized parts network, this wire ensures the burner thermostat circuit operates exactly as the heater was engineered to perform. If you're replacing a damaged or failed thermostat wire on your HI 400HD G, part number is the correct, direct-fit solution.

Key Features

• OEM-Spec Electrical Integrity — Manufactured to the correct gauge, insulation rating, and terminal configuration required by the burner thermostat circuit, ensuring accurate temperature signal transmission.
• Direct Plug-In Replacement — Connects directly into the existing thermostat wiring harness on the HI 400HD G with no splicing or adapter needed.
• Confirmed Fitment — Verified for the Wacker Neuson HI 400HD G Indirect Air Heater series.
• Protects Burner Control Accuracy — A functioning thermostat wire keeps the high-limit control loop intact; a failed wire can cause erratic burner cycling or a complete loss of heat output.
• Electrical Safety Compliance — As a heater control circuit component, using the correct OEM wire maintains the integrity of the high-temperature safety shutoff system, helping prevent uncontrolled burner operation.

The burner thermostat wire carries the temperature signal from the high-limit thermostat to the heater's control circuit, telling the burner when to fire and when to shut down for safety. In an indirect air heater like the HI 400HD G, this wire is a critical link in the overheat protection system — if it becomes broken, corroded, or shorted, the heater may fail to ignite, cycle on and off unpredictably, or lose its high-temperature cutoff protection entirely. Replacing a worn or damaged wire with the correct Wacker Neuson 5100050031 restores the circuit to its original specification and keeps the heater operating safely and reliably.
