Updating the Controls in the Harman Pellet Pro II.

[Shakenbake]

I would say maybe 3hrs total it took me. I worked on it maybe an hour a day over 3 days until I fired it up. Not hard to do at all.

I have a pellet pro ll that both of the boards fried. Does the p38 upgrade kit give you what you need for both boards or does it eliminate one of them? Thanks.

Old Blue is back alive! Control board upgrade seems like a success! I went with the p38 upgrade kit since it uses the same board as p61 now and It was one purchase with everything I needed.

I have a harman pellet pro ll 55,000 btu. Both of the board got fried. Does the p38 upgrade kit give you what you need to replace both of the boards or does it eliminate one of them? Thanks.

I replaced original Pellet Pro II boards in Dec. 2022. I used P61A board set to manual .New wiring harness , black wire exaust gas temp probe and room air sensor. I chose the automatic board as I have a P61 A and thought it made sense to have common parts. Made a tin bracket to mount nicely, small cutout in bottom of new new board for feed control knob shaft. Has been a working well since than. Only thing I question still is the extra steel plate set on top of burn pot cover. It may push flames to far towards glass.
