Hello fellow Enviro owners, and trouble shooters...I hope. My Maxx is shutting down soon after it gets going good. It is very clean including the venting, so that's not the problem. The stove starts up and runs, but then shuts down, and leaves the #3 light flashing. I've performed the following through the technical manual: 1). Checked the damper adjustment, and has plenty of air=flame is good until shut down. 2). Jumped out the combustion motor heat sensor=still shuts down, but no flashing #3 light. 3). Jumped out the vacumme switch=still shuts down. 4). checked the voltage across the combustion motor, and it is @ or around 119volts. I suspect that the combustion motor is weak, so I've ordered a new one. I am eager to learn more troubleshooting information, and if possible how things work with the stove, so I can fix these problems myself as my area is lacking in service professionals. I have strong electrical/electronic/mechanical knowledge, so I will most likely will understand the inner workings of all the parts involved, so the more information the better. As always thank you all for the help, and it is much appreciated.
