Circuit board for non-ignition P61, Invincible RS, Invincible FS, Invincible Insert, P38+, retrofit P38’s that became P38+ and Mag Stoker Coal stove models. All units will use a black ESP probe.
P38 and P38+ Pellet Stoves use this controller. If you have a P38 with 3 knobs, this is the correct controller
P38 retrofits: This is the control board was used to replace the older 2-knob style controllers on the earliest versions of the P38 pellet stoves. Updated units with this controller became the P38+. This upgrade is available for serial 008190059 and greater and is sold as a kit, part 1-00-7738111 which has this controller and all of the other parts you need to change to use this controller
If this is being installed in the Invincible RS Pellet stove you will not need to connect the auger timing microswitch (gray wires) to this board. The new board is already programmed to control the function the microswitch located at terminal “J”. The microswitch and the wires can be discarded.
This controller is NOT compatible with the Invincible T or the Pellet PRO II. Those circuit boards have been discontinued from Harman and are now obsolete.
P61 pellet stoves originally did not come with auto-ignition. This controller is used for those stoves. For P61A pellet stoves, use part 1-00-05886
