Cleaned my quadra 1200i and vent pipe well and it worked well for 2 days. Now it is not feeding properly again but it is a random event. Start the burn cycle fine as the firepot is loaded with pellets. Fire starts and then no more pellets even with call light on. Clearly the auger is not feeding pellets. I push the reset button and feed more pellets then the stove works fine. I have read every thread and there are a million suggestions. Vacuum, firepot gasket, thermocouple, control box. Can anyone provide an educated guess based on the type of behavior. I have no problem troubleshooting the stove but I want to attack this problem by addressing the most likely problem first. Appreciate everyone's thoughts and how to approach the myriad of potential fixes.
