So I spent a few hours working on my Whitfield Pellet Stove the other day, getting it tuned in for Winter. I had to remove a few bits and pieces of hardware in order to free the rusted air inlet or draft control (think flat spatula that slides across the square hole).
Anyway I had the pellet auger motor balanced precariously and when it took a tumble, one of the wires came out of the housing with just a strand of the copper winding wire attached.
Now after attempting to carefully twist that strand around the thicker wire coming from the PCB board, and squish it back in, the heavy-duty, one-RPM motor does not turn.
This is a pretty small unit: for an idea of what it looks like check eBay using "Whitfield Pellet Motor" as a search term.
So looking for any tips as to how to fix this thing. Not sure if anyone fools with crude technology like this -- I just know I don't want to spend 125 USD on a new one.
By the way the pics on eBay show the modern version; mine does not have those spade lugs. |

Hi Disco Stu
I found this link of pics & service notes.
Motor pics are in the 0090's I think.

I'm not quite sure what part you are talking about,
to try & help you.
Any chance you can find a pic on some link to help explain/identify it?
from what I can tell it's a very Low RPM motor (maybe 1-RPM?)
I also found this link on the custom IC, with an X-ray pic as well.

If this is the part?
I have seen & worked on a similar low speed motor, in another piece of gear.
I just need to be sure exactly what you are talking about.
Regards Dr. Bob  |

Thanks Dr. Bob !!
Those links will keep me busy for many hours, looking through all the minutae of Whitfield servicing pointers.
My problem is actually quite basic -- two wires come in from the machine (circuit board or ground) and feed the copper winding on the motor with current. I accidentally wrenched one wire roughly, and it pulled a bit of the single-strand copper winding out.
Though I tried to splice it back together, the motor no longer turns the auger. So I'll dissect it further, and check the current at each wire and throw a jpg or two up.
I'm thinking it's much more basic than a IC or control board issue...
More to come. |
