Hello,
my harman stove is acting very strange. It first started when I turned it up from the idling temp that I usually run it at. Shortly after I noticed a horrible burning plastic smell and some smoke in the room. It continued to run so I turned it off to let it shutdown like normal and eventually it did. I was getting a blink code of 3 (bad esp) so I did a power reset on it but that didn't work, still getting the blinks and it wouldn't shut down after that. It just kept feeding and it left the fans running.
Then, I opened it up. I cleaned the ESP probe and inspected the circuit board. I did not see anything fried on the back side but the ribbon adapter for the power was loose and almost disconnect on the top end. I reseated that and put it back together. Fired it up and it was running at full blast and I barely had the settings up. I turned it off and the fans restarting repeatedly (rather than it cycling down) and it kept feeding strong. I let it get a low as possible and pulled the power to let the fire die out. I plugged it back in with everything off and it did its normal when it's plugged back in and it stayed off. Came back to it a couple hours later and the fans were on and it was feeding pellets repeatedly with dial on OFF and the temp turned down low. I made sure it wasn't on test mode and I had to cut the power again.
Please help. I has a feeling that it's something electrical.
