Hello everyone, new to the forum and a new pellet stove user. I picked up this Castile stove today, a friend bought the home and didn't want the stove. I'm a long time wood stove vet but have never had a pellet stove. Upon getting it in the garage, as soon as it's plugged in the exhaust blower is on. The auger works, and the heating element under the pot works. Even if the thermostat is turned down to where there is no heat call, the exhaust blower is on steady. I stripped the stove down and cleaned it thoroughly, it was caked with ash. The exhaust blower still stays on steady. Any ideas on what could be causing this? Thanks in advance
