All of a sudden I'm getting a error 2 code. Stove will run for hours then shut down and give a error2 no change in pellets. Flame will be bright and nice and blowing hot air into the room. Tried changing the low limit switch still no change.

Any suggestions
Thanks

I would suspect vacuum problem, check hose from vacuum switch were it connects to metal nipple, see if it is cracked or blocked with soot. If cracked trim end and reattach. Could be minor cracks that do not start leaking until hose warmed up. If you have to replace the whole hose it is a special high temp silicone hose not rubber hose. Also do dollar bill test on door gasket. Stick dollar bill in the door, shut door and try to pull bill out, should be good resistance do this all the way around door. Once again door could have good seal until it gets warm. If stove continues to shut down after a couple of hours you could try "jumping" the vacuum switch. Take the two wire off the vacuum switch and connect them together with a paper clip or with a jumper wire. Be careful do not touch wires to any part of stove best if you tape them after you connect them. Then try running stove if it runs correctly then you know it is a vacuum problem. Do this only to trouble shoot the problem not a fix
