From here it looks quite similar to mine, except you have the brass lovers on the sides.
Mine is a '98, and does not have a hopper switch on it .. nor any indication it might have had one.
I couldn't find the name plate on mine for a while ... I was only looking in the back and inside.
My label was on the left side (looking at the stove from the front) ... under the vent/exhaust motor. You might need a flashlight and end up on your hands and feet to see the thing. (well .. at least I did!
) Having the proper model number and year of manufacture really helps in finding replacement parts, and accurate help. These things are pretty generic though.
Mine has a replacement controller on the opposite side has the 3 'magic buttons' along the bottom, the OFF and ON buttons above that, and the 2 sets of up and down arrows .. one for Heat Range and the other for Blower (room air blower). I don't have the model number handy, but perhaps yours has been replace with some similar. If so, diagnostics of basic components is pretty easy, to help eliminate or narrow down failures.
Do a search for 25-PDV controller diagnostics. This process allows you to turn on and off the vent motor, room air blower, upper and lower augers ... all independently. If you can't find it, let me know ... I'll go looking for it. I stumbled on it on the forum here, and was very helpful in determining all my components at least ran on demand!
One good thing to have initially, would be the service video from ESW ... it's free (but maybe only with a purchase, I don't know ... ) It shows how the augers and blowers come out and go back in ... visually.
In normal operation, the upper auger doesn't run continuously. One of the things the Heat Range buttons do, is control the rate of speed the pellets are fed from the hopper to the lower auger .. via the upper auger. It runs for so many seconds, then stops for so many seconds, and repeats. Sounds like yours isn't moving at all. It isn't difficult to remove the augers. One set bolt allows the auger motor to be removed, and then you have easy access to the 4 bolts that hold the auger bearing/auger assembly. It comes out all as one piece. Of course, it's best to remove the augers with an empty hopper! ;-)
The auger should turn freely, and without significant wobble in it's bearing. Mine has quite a bit of wobble in the lower auger, but so far, just results in an occasional squeak. Both of my auger bearings have grease zircs, so I loaded them up with grease before re-assembly.
Hope this helps. Kinda generic, I know. Most all above I gleaned from other helpful folks on the forum, or taking things apart. Your mileage may vary .. ;-)
Best of luck!
