When I start the unit everything works as it should except the auger will turn for about 15 secs and then turn off and not come back on. I tried starting in safe mode with Limit and vacuum disabled, same thing.. Tried jumping vacuum switch wiring. Took pellets out of bin and made sure auger was not plugged. This was just after I deep cleaned it so I am puzzled if it could be something I did or coincidence. I checked wiring were I was cleaning, got me puzzled. Went thru all the company videos and am stumped to where to go. When I go into diagnostics to turn auger on it does same thing.
Comfortbilt HP22 Auger quits turning.

I took all pellets out of bin and vacuumed all fines and pellets, auger was loose, took both cleanout lids off and vacuumed, took cleanout of chimney bottom and vacuumed. I ran the auger power test and could feed pellets continuously and partially fill pot. I ran ignition and got a few pellets fed initially, it lit as normal and had a strong flame, about the time you would expect more pellets to feed, it would not and fire would eventually go out. Tried running in safe mode vacuum and limit, the same. Tried manual operation vs temp which I normally run, no difference. Lid switch is working according to diagnostics.

Or a proof of fire. Check the manual for location (should be near the exhaust blower motor) and jump it. Unplug before pulling wires. Then see if the stove runs correctly.
When I jumped the proof of fire switch it started the exhaust fan and it would not let me go into ignition. My model also has a secondary proof of fire switch which I had switched to in previous attempts with no resolution. I have a manual which I pulled online and have followed troubleshooting to no resolve. The only cleaning spot I have not done is removing the exhaust fan and vacuuming but had done that at end of last year. I have ordered a control board and card.
I would pull the motor and clean, just to cover the bases on the stove
I pulled the exhaust fan and vacuumed both ways with my 18" small tube, looked good. I have new gaskets on order for cleanout doors too. If I had a bad vacuum leak, I wouldn't get a strong flame at startup after I manually get pellets into the pot, would I? I have not been able to find out how the rate of pellets is controlled. If this is done at the control card that would be my next culprit I believe. I am waiting one to come in.

The best way is to jumper out things external to the card. It is not normally possible for an owner to "link in" to the actual card (if it is a type with a controller on board). If you could, you could troubleshoot within the card. Sometime parts on the card will fail (triac outputs) and they either fail shorted, or fail open. In that case if the bad part can be found they can be replaced. An example would be if you looked at the card and saw something damaged.

I really bad leak should cause no pellets as the vacuum switch would not pick up. If it is a good strong flame with no black tips and no carbon then yes, that is a good sign.
The rate pellets are fed is programmed into the control board. Best troublshooting is exactly like Whiteknuckler said👍
Well, I replaced the control board and control card and everything works as it should. Thanks to everyone who helped me along my journey to get my pellet stove operational again. We sure missed it!
