The thermostat knob is the control interface for the temperature regulation system on the Yarrman Boiler stove. If the existing knob has cracked, snapped, or become stiff and hard to turn, replacing it restores smooth, accurate control over your stove's heat output. This is a direct-fit plastic replacement for the Horse Flame Yarrman Boiler HFB717.

✅ Compatible with: Horse Flame Yarrman Boiler (HFB717 / HF717-B)

🔧 Specifications

  • Material: Heat-resistant plastic
  • Part type: Thermostat knob / control knob
  • SKU: HF-MP-03

The thermostat knob fits directly onto the thermostat body mounted on the stove and allows you to set and adjust the water heating temperature. A worn or broken knob makes it difficult to regulate the boiler correctly, so replacing it promptly keeps the stove safe and efficient.
