Wacker Neuson 5000168656 Control Knob

The Wacker Neuson Control Knob is a genuine OEM component designed for the HX50 Heat Exchanger, HX100 Heat Exchanger, and Pureheat Hydronic Heater series — including Oil Burner, Gas Burner, and Diesel configurations. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original installed component. It is a direct-fit replacement for all listed Pureheat and HX-series hydronic heating units, ensuring proper operation of the heater's manual control interface. If your current knob is cracked, stripped, or missing, part number restores full functionality without any guesswork.

Key Features

• Genuine OEM Specification: — Manufactured to the exact dimensional and material tolerances of the original, ensuring the control interface operates with the correct detent feel and positional accuracy required for heater adjustment.
• Direct-Fit Replacement: — Mounts directly onto the existing control shaft of your HX50 or HX100 heat exchanger or Pureheat hydronic heater — no drilling, re-tapping, or adapter hardware needed.
• Broad Heater Family Coverage: — Compatible with the HX50, HX100, and the full Pureheat Hydronic Heater lineup, including Oil Burner, Gas Burner, and Diesel variants.
• Operator Control Restored: — A damaged or missing control knob makes precise temperature and output adjustments unreliable; this replacement restores clean, accurate control over your heating unit's settings.
• Fuel System Safety Relevance: — On fuel-fired hydronic heaters, positive and accurate control input is critical for safe combustion management; a stripped or broken knob can lead to unintended setting changes during operation.

The control knob provides the manual interface between the operator and the heater's internal adjustment mechanism — typically governing temperature output, burner settings, or operating mode selection. When the knob is intact and properly seated, it transmits precise rotational input to the control shaft, allowing the operator to make accurate, repeatable adjustments to the heating unit. A cracked, stripped, or detached knob compromises the operator's ability to control the heater reliably, which on fuel-fired equipment can create unsafe or inefficient operating conditions.
