I have a CAB50 that is about 1 1/2 - 2 years old, I bought it this summer and it has been working fine for the most part until yesterday. It had a clinker while my wife and I were away for a family Christmas so when I got home I cleaned the fire pot out and restarted the unit, and it started fine. The exhaust fan came on, pellets fed in, the flame ignited, no issues, but once the blower fan came on it didn't feed any more pellets and eventually went out. I have tried restarting several times and it continues to do the same thing, once the blower comes on the pellets stop feeding. any ideas?
