So I recently had a problem which was resolved when the tech that came out found a drill bit stuck in the hopper. Now the pellet stove works but changing the heat levels seems to have no impact. It seems like no matter what setting it’s on the output is level one (lowest). Initially when this happened it wouldn’t change unless you went to level 5 and then it kicked all the way on. Not it stays at the lowest level. Both the fan speed and pellet output are low. Any ideas? Thanks in advance.
