Hi All,
Well for the first time in 7 seasons of running this stove, I ran into a pretty significant issue. I was reading in front of our stove this afternoon with it running on 7-9 for about an hour and a half. I noticed that the room blower had turned off. It didn't make any unusal noises, just shut off. The meat thermometer that I placed in the blower holes was reading about 300, which I've never seen before. It usually tops out around 225 or so. I figured that the blower motor probably overheated, and was thermally limited. I expected the stove to go into overheat mode and shut down the pellets, but to be safe, I lowered the heat to 5. Well over the next two minutes, the pellets didn't stop feeding, and the temp on the meat thermometer went past it's limit at 500, probably close to 650. I pushed the off button, and the flame slowly died down. After about 10 min, the room blower came back on and the stove cooled down.
I've had a few times when the stove has gone into an over fire situation and limited the pellets, but I haven't had a situation where the blower got so hot that it shut down. I'm especially concerned that the overheat mode didn't shut down the pellet feed.
I put the stove in diagnostic mode, and I appear to be getting a reading on the thermocouple (3-9 while cooling down) I'm suspecting that the thermocouple may be giving a bad reading. I'm planning on breaking down the room blower and cleaning it out again, but the room blower shouln't have had any effect on the overheat limit.
Any other items I should be looking at??
