The Wacker Neuson Thermocouple Cable Complete is a genuine OEM component designed for the HSH350 hydronic surface heater series. Sourced directly from Wacker Neuson, this cable assembly meets the original electrical and thermal output specifications required for accurate temperature sensing in the HSH350 system. It is a direct-fit replacement for both the standard HSH350 and the HSH350 DG 50Hz surface heater configurations. When your existing thermocouple cable degrades or fails, swapping in the correct OEM assembly restores precise temperature feedback and keeps the heater operating within its designed parameters.
Key Features
- Calibrated Thermal Output: — Genuine OEM construction ensures the cable delivers accurate millivolt output across the full operating temperature range of the HSH350 — no signal drift, no false shutdowns.
- Complete Cable Assembly: — Supplied as a complete assembly with connectors intact, allowing direct plug-in replacement without splicing or field modification.
- Verified HSH350 Fitment: — Confirmed compatible with the HSH350 hydronic surface heater, including the HSH350 DG 50Hz variant, covering both common configurations of this machine.
- Heater Control Integrity: — A functioning thermocouple cable is what allows the burner control system to regulate heat output; a failed cable can cause nuisance shutdowns or prevent the heater from firing at all.
- Safety-Critical Sensing Component: — In indirect and hydronic heating equipment, accurate thermocouple signal is essential for flame supervision and overheat protection — fitting the correct OEM cable maintains those safeguards.
The thermocouple cable in the HSH350 hydronic surface heater is the sensor link between the burner flame and the heater's control circuit. It generates a small electrical signal proportional to the heat it detects, which the control board uses to confirm the burner is lit and to regulate heating cycles. When the cable wears, corrodes, or develops an open circuit, the control system loses that signal — typically resulting in the heater failing to start, locking out after ignition, or cycling erratically. Replacing the cable with the correct OEM assembly, part number 5000173658, restores the integrity of the sensing circuit and returns the machine to reliable, controlled operation.
