So oddly, stove was shut down and plugged in over the weekend. Went out and returned home and stove was running not ignited, but just running and spilling pellets over into the ash pot. I had to turn stove off by unplugging it. This is baffling and a bit concerning. The stove is now flashing three times in the status light. Anyway I’ve read that the 3 blink status is an esp probe problem. So I cleaned it and put it back and still the same problem. That did not resolve the problem after plugging it back in. I’m going to try replacing it today. I can’t explain why the stove will not shut off when in off position. I have found some threads that discuss this issue, but no one posted how they finally resolved the issue. Any help would be appreciated.

It could be a problem with the potentiometer, aka pot, which may have a dead spot. Try using an electronics spray contact cleaner and working the knob back and forth a few times. I had to replace the pot on my stove to solve it.

Ok so I changed the esp probe and of course still the same problem. I see they sell the pots on eBay. I’d assume it’s cheaper to try to replace this before replacing the whole board. How difficult is it?

Jackman - just wondering if your stove was doing what my stove is doing before you had to replace the pot? Was it giving you a three blink status? Mine has the three blink and the Fans stay on when knob in off position like it would if you turned stove off and there was still a flame. When I turn it to stove temp the stove try’s to feed but the igniter never engages. I thought to try and light the stove manually while in stove temp to see what it does???

I don't remember exactly but the way the problem was made apparent was when the stove kept trying to start even in the off position.
