Replacement Harman Platinum Control Board!!!

My distribution fan was failing to turn on when the stove got hot, which is a huge problem. The fan needs to run to distribute heat into the space where it is installed, or it is a hazard. I founf the cpu/thermistor connection on the CPU to appear badly damaged, and the probable failure. I replaced the CPU (pretty easily with a few videos), all you need is a flathead and some CARE. I snipped out the old thermistor (I did not want to rebundle the old wiring), and I replaced the thermistor (red wire) (which attaches to the CPU). Set the dipswitches to the appropriate settings with a small screwdriver or pin. In my case it was 00001110, which matches the Accentra 52i pellet insert that came on the provided guide (YES, it is included, as are knobs and knob shafts), as well as the old dipswitch settings on the board I was replacing, so I was confident I couldn't really mess that part up. The stove is working great and the distribution fan is now running properly. This is a good buy if you own an Harman Accentra 52i pellet insert (NOT a "TC" model in my case, which I believe has a digital display) with a failing cpu/thermistor. It fit perfectly, no struggle, this is the board made for this stove. Be CAREFUL when handling the board, do NOT bend the pins, and don't damage the board when you are remounting it to the control plate!!!!

My XXV stove was starting to exhibit the dead spots in two of the adjustment potentiometers. The stove would not keep the room temperature well anymore and the blower fan speed adjustment was very touchy, to the point that the fan would not run on high speed without tapping the knob occasionally. This is on a 8 year old stove mind you so I can't complain, HARMAN is a great stove.I read about getting replacement potentiometers but I didn't want to set up a soldering station and my hands are not as steady as they used to be. I saw the replacement circuit board and decided to go that route. I could have gotten one down the street at the stove shop where I bought the stove initially, but I'm cheap and didn't want to pay their prices. The only reason I might have gone there is because they would install and replace it if it was defective. Online I didn't have that choice, no returns. I swapped out the board yesterday and I immediately have seen a vast improvement in the stoves operation. The temperature is not as erratic and the fan speed is constant. Also, the off position on the stove temp/room temp knob now has an indent for the OFF spot. Super easy to swap out, just pay attention to the wire color going to the ESP connector for your stove. The number 5 dipswitch is on or off based on a black or red wire. I screwed up initially and had that switch in the wrong position and the stove will NOT work correctly. You will tell that immediately. This is an original Harman board so don't worry about a knock off or imitation. Works great..Worth doing yourself. Stove had never run better.

I changed out my circuit board after reading the paper work that came with it.My old circuit board was set at the factory so I set it at the same settings. And it didn't like my esp sensor that worked fine with my old board.But once I reread the settings and which switch's did what I set it to hi altitude and timming for ignitor and my P61 stove ( replacing the fuse) it has now been running flawlessly .Because of the expense of the board I didn't change it out. We suffered for a few years with it acting up.It finally wouldn't shut off. The off position between stove temp and room temp wouldn't work any more.The new one now has a detent on the off position, much nicer then the old one.Now the stove shuts down within forty-five min.I've had this Harmon stove for 17 years. By far this is the best stove on the market.It heats our 2000sq' house perfectly.100 bags a year. Doing a good through cleaning pre season and it's ready to go.I don't even change out the ash can all winter.100 bags don't produce enough ash to warrent it.Thanks Harmon.Our P61 lives on number 1 feed and no need to change it. Sets at room temp hi some times in the evening we need to turn it down to low.We shut it off when we go to bed.Do a quick clean to the ramp in the morning by pushing everything back into the bottom of the ramp. Using the tools ( straight edge is best) wire brush the top holes area and off she goes.This is now finishing up on its 18 the winter.still have about 25 bags to go.

Board works perfectly and installed well. The loss of one star is because they didn't have any useful instructions about removing the existing board. It's really straight-forward if you know one small detail - there's a slot in the Harman side panel that makes it easy to manipulate the board into position and Lift it up about 1/2 inch so it's easy to remove. If you're not aware of that slot in the Harman design, it's awkward. So, -1 for not providing simple, useful detail. Overall, a great replacement board for a P43.

Pretty easy to install and saved us a great deal of money in not needing a service call. Just follow the instructions setting the dip switches for your stove.

Board worked great after figuring out the model and exhaust sensor color. Had to replace my sensor to red the black one kept acting weird. Stove works better than I ever remember.

This control board worked perfectly. Save me a significant amount of money to have the service tech replace it. I had a couple of questions called the seller, and they entered all my questions.
