Classic Bay 1200 - Auger stops after adding pellets

This is my first post to this forum, please excuse any faux pas. I have searched this forum and Google for an answer to this specific question, but could not find one.

Three weeks ago I purchased a new Quadra Fire Classic Bay 1200. Often, after adding pellets, the auger would stop for a while. Over the weekend, I added pellets and the auger stopped feeding pellets at all.

I checked the following:

1. That the door and ashpan are sealed. The door on the bottom of the firepot is closed completely.
2. I removed all of the pellets from the auger assembly and vacuumed out the pathway from the bottom using a wet-dry vac.
3. I used a flashlight and a mirror and viewed the auger at the output end to look for obstructions. I also used a coat hanger to get in there and see if anything was causing a blockage. The auger moves around freely up/down/left/right, but won't turn when manual pressure is applied to twist it.
4. I checked that the pellets are emptying in to the auger correctly, and aren't getting stuck by the feed bar being too closed.
5. I looked at the vacuum sensor at the back of the unit, and blew air into the hose (as I saw online) to clear out obstructions.

I'm at a loss of what exactly to do next. Could this be a hopper door sensor gone bad? If so, how do I make the sensor trip properly? Has my auger motor gone bad?

I am looking for ideas on what parts of the stove I should be looking to work on. The store I purchased the stove from has a two week+ maintenance backlog and I can't afford to wait that long.

I am somewhat handy around the house, installed steps, bathroom fan, some minor electrical, build my own computers etc, so I just need a push in the right direction. Due to circumstances, I also watch our four month old daughter all day, work nights, and stay up with the baby at night. I've been working on the stove in 15 minute increments, or in the early morning.

@hooter04 & @tjnamtiw Thank you for your responses.

It turns out that the hopper magnetic switch is not working. I tried attaching the hopper door magnet to the sensor and that did not work. I then removed the sensor cabling from the connector at the vacuum switch, then jumped the connectors, and then the auger motor started working and my problem is fixed. Thank you!

Now I need to convince our dealer to send me the part without having to wait for a service call, or just purchase a replacement part of a suitable price online.

Thanks again!

Yes, now there is less mystery about the stove and how it's constructed and wired. That's going to help the next time I need to make a repair (hopefully a long time from now).

Good point about the voltage. I made all the tests/connections with the stove unplugged. The stop-gap measure is an 10A alligator clip across the female bus connector pins, wrapped in electrical tape. Based on the other electronics in that area of the stove, it doesn't look like the section I'm working on gets much heat, otherwise the OEM parts would have melted.

Always, always, unplug. It's better to be inconvenienced than get current across your chest, or even worse, blow a control board.
