  • Correct Wire Color – Avoid Mismatches​:For Harman stoves use two types of thermistor ESP probes: Black‑wire​ and Red‑wire. Always order the same wire color as the original part you’re replacing. Note: The Black‑wire ESP can also substitute for earlier White‑wire ESP probes.

Also compatible with Harman Wood & Coal models DVC 500 and Mark I. Replaces OEM part numbers 3‑20‑00844, 3‑20‑00906, and 32000906​ for a fit and reliable performance.
  • Built to Last:Both the 3‑20‑00844 ESP Probe (Red Wires)​ and 3‑20‑00906 Sensor Thermostat Probe​ are made from high‑quality, long‑lasting materials. Designed for extended, safe, and dependable service so you can enjoy worry‑free heating season after season.
  • Smart Temperature Control:The 3‑20‑00844 red ESP thermistor probe​ sends precise temperature data to the control board, while the 3‑20‑00906 pellet stove temperature probe relays room temperature to the stove’s system, enabling automatic heat output adjustment for consistent comfort and improved efficiency.
  • Simple Installation:Plug-and-play design for hassle-free installation.The 3‑20‑00906 room sensing thermostat probe​ adjusts stove heat output according to your set temperature when operating in Room Tempmode.
