Hello, I've got a 1992 Austroflamm Integra that I've had for about 3 years. I can't get the combustion fan to start. I've checked the low limit switch with a lighter until it clicked and the convection fan came on. The auger motor turns and drops pellets also. I don't think its the control board, but It could be. I don't know what else to do to get the combustion fan to work. Has anyone else had this problem and if so, how did you resolve it? Any help would be appreciated. Thanks, Don
