I have a CB1200 pellet insert. This morning, the power went out for a few seconds at home. When the power came back on, the stove "beeped" and the fan came on. I was surprised as the stove has not been on since May. I unplugged the stove and when I plugged it back in a few hours later, the fan started up again. Any idea what the issue is or what I should do? Thanks.
