Noob here and I need help with my Enviro EF4. A short time ago the stove just started to stop feeding pellets and the exhaust/combustion blower just stops while the fire is going, filling the room with smoke. It's not shutting down-it just stops. The auger light stays on (there is only 1 light to indicate when the auger is turning) but nothing is turning. Once this happens I have to let the stove sit and reset whatever is going on (unplugging does not reset it). It has slowly gottten quicker and quicker as to when it shuts off, so that maybe 10 sec. after it starts up it stops (without anything having lit obveously).
I have bypassed all of the sensors (1 at a time) and it does not seem to affect the problem. When I bypass the vacuum switch the auger will turn, but the exhaust fan does not come on. When I bypass the 140' exhaust temp sensor, the fan temp. senor, the ignition temp sensor, and the high limit temp. sensor have no effect. The high limit temp. sensor has not tripped. I have bypassed them when the stove was stopped (as the auger light just stayed on) to see if it remedied what was causing the error. Should I wait to bypass them when the stove is running properly?
The stove has 3 solid state, 2x2, timer control switches. I tested them all and have power coming out of all of the load portions of the switches (I don't know if this conclusively proves they are working properly). I replaced the auger timer control recently, so I know it is working. The blower control timer also works independently of the error. The third one is the start up timer control. This one bypasses the low temp. sensor so the stove will run when cold. I thought that perhaps this switch is bad, but can't figure out why it would cause the stove to stop functioning with the sensor bypassed. The auger does not have power going to it when the light stays on and the stove stops functioning. I am at a loss as to what is going on. This isn't a coplicated stove but nothing seems to make sense. I thoroughly cleaned the stove (including the exhaust pipe) and I checked the vacuum hose and oulet for the hose (there was smoke coming out of it when the stove shut down once, so I know it's not blocked). I have also replaced the exhaust blower since the problem started-same result. It doesn't seem like it should be this difficult to solve. Before I start throwing parts at it anyone have any suggestions? I am planning on selling the stove at the end of the season, so I don't want to spend a lot trying to find the right part to fix it. The two photos are of the Solid state timers. The second photo is of the start up timer control module (on the bottom of the 1st photo).
