Utilized last season, as well as this season in new location in home (replaced old wood stove - feeds into brick chimney versus out through wall). Detailed/cleaned unit couple of months back and have typically used Room Temp, temp setting 70, auto igniter and feed limit 4; these setting worked in both locations. Lately it seems I have had to increase temp to 75 or more to get same results and turn feed limit up to 6 without getting close to enough pellets in burn pot; way less than the 1" guideline. Stove shuts off seemingly early and doesn't come on unless turning up temperature (even when room is cold); we have been in the mid-30's lately. Removed/tested the room temp probe (removed shrink sleeve over probe), using an ohmmeter, it seems the sensor wire is fine, visible resistance changes based upon temperature (not sure what the values should be though). No adjustments were made by company that relocated the pellet stove concerning draft settings. Flipped over to constant burn, temperature setting 3.5 to 4 and feed rate to 4 and it seems to be working like before. No error codes (flashing lights), wondering what I should check to possibly remedy. I have a new 3/8" door gasket to install (pellet dust around stove); any suggestions?
