I have been trying to troubleshoot why my Enviro Empress was having poor throughput of pellets. I might be onto something. There is a light that pulse on the control panel each tie the auger spins. Recently, I have notice 2 different sounds coming from the stove...the normal sound of the auger spinning and then a faint hum. I contacted Enviro tech support and confirmed tha the auger is supposed to spin/move with each light pulse on the indicator. This is not happening. Approx. 30-40% of the time when the light pulses, the auger does not move. I opened up my stove tonight to look at the motor. There is a little cylinder on the motor that spins at a high rate of speed when the light pulses, or at least, this is what is supposed to happen. Frequently, the light will pulse, put the little cylinder will not spin, and it emits a humming sound. I'm not sure what this part of the motor is...it is a magnet that spins when electrical current is applied? I had a cheap pool filter like that. Is my auger motor shot?
