Hello everyone I'm new to this group. I have a ECO-CAB50 and the pellets will not feed into the burn pot. I have check the vacuum tube. Removed auger checked for blockage in feed tube. Still nothing. Call light is on exhaust blower starts but no feed or ignition. The exhaust blower remains on. It worked last night now nothing.This is the third year I have had the stove. Could it be the control box
