Went to turn off the pellet stove (VG 5790) as usual by pushing the power button on the side panel, but instead of initiating the shutdown sequence it completely turns off everything for about 2 seconds and then turns back on and continues to run as normal. Tried several times with the power button on the side panel and on the remote, no luck. Looks like I'll just have to let it run out of pellets. Any thoughts on what might be causing this? The stove is about 4 years old and just had a full cleaning to start the season about 3 weeks ago.
