Subject: Bad exhaust fan sensor? - by: hub0000

If the exhaust fan sensor is bad would the exhaust fan just run on what seems to be it's highest speed and not be able to control it with the trim nob? Got a #7 error last night after an ash dump so turned power off. When I turned it back on during start up it got pretty hot and according to my temp probe I was getting like 260 something degrees out the grill. Since that happened I can't slow the exhaust fan down and the pellets burn to fast to get a good fire.

Interesting occurrence with little girl this morning. Started her up just to take the chill off the house. Temp outside...45*, damp as heck with rain and snow melt. Went back to the kitchen while she did her thing. Heard all the normal sounds, corn tinkling, ignitors coming on, air pump kicking in...until the pump cut off too soon. Didn't run long enough to get the corn burning well, had to force 2 dumps when the pot started to overfill. Dug out a clump of unburned corn from the pot, bumped heat level to 3...she seems to be doing fine now. Corn level back down where it should be. Hadn't touched the trim, stove cleaned two days ago, I just shut her off yesterday because it was hot in here.

I'm hoping it was just an anomoly...maybe too much damp in the house because of the rain, fog and snow melt. Can't imagine why the air pump would drop out so quickly. It usually runs a couple of minutes, gets a good burn going. I'd estimate she ran less than a minute then quit (ya'll know how we "hear" when something isn't right with our stoves). I'll be shutting her down as soon as the house is dry and warm, headed for the 50's and rain all day. Probably won't have to restart until tomorrow morning. Wish me luck that this morning was a fluke, any thoughts on things to watch for would be greatly appreciated.

My 110 seems to burn a-ok for a couple of days @ level 6, then jams during ash dump. Done this twice recently. Been told this may be a symptom of lean burn, but if I up the feed rate or slow the exhaust fan speed, then I wind up with build-up in the pot. Any suggestions?

Seemed I had this problem last year. Rona told me to look for an exhaust leak with a flashlight when the room was dark. Can't seem to find any kind of leak. My 115 is due for a cleaning but it doesn't seem that should be the cause. A week or so I was putting the cable back into the board and accidentally hit the exhaust knob and turned it to -5 and the stove ran super rich for about twelve hours blackening the glass almost entirely. It was until this point that everything seemed clean. Any suggestions to why I would have soot in the grille and probably blowing it into the room as well and also inside the hopper lid has soot on it. I am burning wood pellets and have the new style gasket on the feeder wheel cover and a new gasket on the exhaust fan and replaced all the screws in the cover with nuts and bolts.The only other factor could be the weather, as we had severe 40-50 mph winds with the blizzard the other day and the exhaust pipe was certainly taking the brunt of the wind..Bob

had service call today, stove had overfills and would not run on higher numbers, cover plates for heat exchanger tubes were put in backwards, looked ok but restricts air flow, probably on wiki but just a reminder

Subject: Convection Fan Shut Down - by: ileed

This problem started last year. The stove can run a number of hours, setting 4, and the convection will shut off. The fan bearings are quiet, and no lights flash. After 30 seconds and some clicking the fan will get a bit of power, and shut down for 30 seconds, and finally start back up.

This year the stove ran a month before the ugly reared its head again. About this time I had an igniter go out, and I called Bixby for warranty. When Mike returned the call I spoke with him about the fan, and he said it was due to overheating bearings, even if they made no sound. He sent me an igniter, and replacement bearings. I replaced the igniter, and the board went out. After sending my board in, it took Mike 2 weeks to send a replacement. Meanwhile I changed the bearings.

After putting in the new rebuilt board, and running a day, the fan has begun to shut down, and restart again. It would seem the bearings were not the cause of the problem. Any ideas, please.
