My Hearth unit has always had a noisy stoker motor. I ran it from December 17 last year until mid March and before firing it up this year I took it all apart to clean, inspect, lube, etc. The stoker gearmotor has grease in it, but due to it being mounted at an angle and being near the hottest part of the stove I found all the grease had melted and collected at one side of the gearbox. I moved it all back onto the gears, but I'm sure by now it's all back at one side again. Is there a grease that will not melt at the temps the motor is subjected to?
My main question is, how noisy is your stoker motor when it runs? Mine has always sounded like it's grinding and is amplified by the steel stove body. Sounds a lot like an electric can opener running loaded with a can. I tried isolating the motor assembly using RTV, stove gasket, hi temp RTV sheet, you name it, but it's still quite noisy. The motor running in your hand is near silent so I know it's the stove itself amplifying the noise/vibration. My buddie's Alaska Channing only makes a very slight ticking noise so I wonder if maybe my gearmotor is a noisy one or if it's just the design of the stove?
I'll probably video mine tonight and post it if I can get the audio to sound correct.
Thanks in advance.
