Can't get Harman XXV out of test mode

Today shut the stove down to do a routine cleaning. Left for a few hours for it to cool down and started to clean when I got back. This is the first time I turned the stove to "test" to vent the stove when cleaning after reading posts about doing this. My cleaning consists of emptying the ash pan, vacuuming the stove, brushing ash off all sides and fins, emptying the fines box, scraping and vacuuming the burn pot, and cleaning the ESP.

Now after finishing the stove will not turn off even when the temp knob is in the off position. The combustion/blower light is the only one lit, besides power, and there is nothing I can do to stop it short of pulling the plug. The auger is not feeding pellets and turning the stove to stove temp or room temp does nothing. Short of contacting a dealer is there anything else I can try?

I've tried that. Turn it back on, set the temp knob and the blower just runs.

Never got any blinking light status when it's on. Spoke to the dealer I purchased it from to run everything by him. He basically suggested everything that's already been done. Said he's not really sure what's going on until he takes a look at it, I have an appointment scheduled for later in the week.

I have a sneaky suspicion it's the circuit board. Double checked the hopper lid switch and exhaust probe and believe those are working fine.

Had the tech out this afternoon, turns out it was the combustion blower. That and the paddle fan was replaced. This was the first time the stove has been serviced since I purchased it back in 2012. He was amazed at how clean I keep the stove and stated he was surprised that I hadn't noticed anything with the combustion blower before. Asked if I had ever heard the stove screeching which is a sign the motor is going. I've noticed that a couple of times over the years but thought maybe the auger was dealing with some difficult pellets.
