my harman p61 runs fine but it will not shut down. I had the tech out and he shook his head and said he would have to call the harman rep charged me 250 dollars for a 20 minute visit. phoned a few days later to say it is the control board but would not stand behind the cost if this was not the problem. as I said the stove runs fine no blinking lights ,the power went out and when the power came back on fire was out stove was cold but all the fans were running and it ran a whole hopper of pellets into the ash pan.
