Harman Stove PP38+

Hello I am new to this board. I have a Harman PP38+ pellet stove. My problem is my stove doesn't produce enough heat to cause the blower to turn on causing my basement to stay cold. It stay's lit (it's just a small flame no matter if I turn the feed knob all the way up). The only way I get the blower to work is turn the stove off and then back on the blower blows warm air and the auger feeds the pot to cause a large flame (but after about 45 seconds the blower turns off and the flame get smaller). Someone told me to buy a new circuit board but also was told it might be the knob for the feeder? Any suggestions? Thanks

You might get better results if you post in the Pellet Stove area. Good luck!

Thank you for the help.
