Harman p61a will not properly

[KKremp]

A few days ago I tried to shut down my Harman p61a for a cleaning which was long overdue. I left it overnight to cool but in the morning the combustion and distribution blowers were still running. I unplugged it and tore it entirely apart to clean it. Removed entire stove pipe and pulled the esp probe to ensure everything was good. Now that its back together the blowers still run as soon as its plugged in, even though the switch is off. The stove will light and run well for a few minutes anyway. However the auger will not feed pellets fast enough even when turned all the way up. It normally runs at 3. There is also no change in the fan speed between high and low settings. Once its ran for a bit the fire burns very low in the pot. It has not thrown any error codes. It does work just not as it should. Help please. Last year I replaced the circuit board and esp probe. Could one of these be the culprit again?

What mode are you running in, room or stove temp?

I have tried it in both. It was just feeding pellets in the off position as well.

That has happened to me in the past when I tried to shutdown. Do you have a surge supressor on it? If so, take it out of the line, unplug the stove for a minute or two, and try it again.

I did have it with a surge protector. Unplugged it for a couple hours with the same result.

Did you get rid of the protector for your test?

You bet

Then my guess, unless someone else has other suggestions, is either the probe or ESP wires need to be relanded or checked for continuity or the board is fried. There are people on ebay who will check and refurb the board.

Sounds like you need a new esp.
