Harman 3-20-05378B, 3-20-00928 control board, fits Invincible RS, Invincible Insert & P61 pellet stoves. These Harman model pellet stoves did not have auto-ignition.
Board is brand new and is leftover inventory from when I was a dealer. The board must be used with the black ESP probe, not the red one. If you have a red ESP probe, you must use a board with dip switch settings, which this does not have.
I will take it out of the static proof packaging and take pictures. Any questions ask and I will try to answer.
