I own a KC Combo and have had a weird issue turn up. I went outside to look at something on my deck when I noticed that the fan was running on my grill. I made sure the grill was off, then unplugged it, plugged it back in, then went about my day. About 30 minutes later I went back outside and the fan was back on. I know that the fan runs after you turn off the grill, but this was hours later. I contacted Pit bos, they sent me a new control board and a fan. Even after this fix, the fan keeps turning on randomly. My grill is in the sun, and gets quite warm during the day. Could this be a failsafe type of thing when the grill gets too hot when not in use?
