Hi, all. I've been using the new to me Accentra for over a month now and it's been great. The stove is not new, but was cleaned by myself before it was installed. It's been throwing a 6 blink code every now and again, but would usually restart and run great for days after a reset. I make sure the burn pot is clean, the exhaust is clean, etc. Today the stove refused to stay running. I tried several times and it will ignite and start, but then shut down with 6 blink code. According to the manual it means "incomplete combustion". There are no unburned pellets in the pot when that happens and during the time it does run the fire is lively. I am guessing the exhaust temperature probe (called ESP probe by Harman) may be bad tricking the controller into shutting down. Any ideas before I go replacing the sensor? Thanks in advance!
