I have a Harman Accentra Insert stove that is approx. 8yrs old. It's worked fine with a few minor clithches up until about 5 days ago. I had just completed cleaning the burn pot and ash pan. The unit restarted properly and was running fine, the next morning I look at the stove its out, stone cold, but the LED's for the combustion blower,feed auger and ignitor are all on. None of these items are working, the auger won't feed, no combustion blower, and the ignitor won't light. Anybody run into this problem before?

Have you tried to unplug the stove from the outlet, maybe this will reset it. If the combustion blower doesn't run, even though the lights for the auger and igniter are on, they are not getting any power to be on. The combustion motor has to run to close the vac switch which in turn will power the igniter and auger. Also,when the stove is not powered, make sure the combustion blower motor turns freely when turned by hand.

I've unplugged and plugged in the unit several times, with the same results, the combustion motor rotates freely. If there is an open circuit to the motor that will prevent the remaining components in series from turning on?

The combustion motor has to run to close the contacts on the vac switch. When these contacts close, the auger and igniter both are powered, so, you need to determine why the combustion motor won't run. It could be that its not getting power from the controller or its getting the proper voltage and the motor is bad. A voltmeter and knowing how to use it (not difficult)would be very helpful at this point.

Already did that. 0V between the white, red, yellow and feed motor black wires. Control Board problem?

Did you unplug the 9 wire plug from the controller and measure the voltage at the pins of the control board where the red and white wires connect? If no voltage can be measured on the board when the stove is powered on, my guess is that the controller is toast.
