Hello. I have a Enviro EF3 insert that is about 8 years old (does not have circuit board) and the auger will not feed pellets.
Things I have tried to fix the problem include:
* Cleaned the clean out at the flue
* Fed a hose and a 12 ft pole from the top of the chimney down and fed an 8 ft hose from my ShopVac up the chimney in an attempt to clear any obstructions. No obstruction found. The chimney is 16 feet and has a 4" diameter liner.
* Removed the exhaust motor and thoroughly cleaned it and all of area around it. It appears to be working as it blows exhaust, although I do not have a magnehelic pressure guage.
* Applied direct power to auger and it works
* Cleaned the entire firebox and around heat exchanger tubes.
* Checked the gasket around the door and it is tight
* By-passed several circuits including the temperature sensor, the vacuum switch and the auger timing module. None of this has fixed the problem
* Checked the vacuum hose for leaks and the ports for clogs
I did not remove the convection blower and clean around it but it does blow air and seems to work.
I am stumped. Everything seems to be clean and everything seems to work. Unless the exhaust blower is bad and not producing enough vacuum or the auger timing module is bad I do not know what could be wrong. Any ideas appreciated. Thanks
