I have a Quadra FIre Mt Vernon. Earlier today it made some loud grinding sounds and now when I turn on, the blower turns on but the feeder will not. I have checked the vacuum hose and still nothing. The fan seems to stay on when plugged in even it thermostat is off. I hit the reset but but still no pellets will drop??? Any suggested. I emptied the hopper and there does not appear to be a jam??? Any way to check if the feeder/Auger is OK. Thanks, Kevin
