The Quadra fire system needs to have a vacuum inside the firebox in order for the auger to work.
First you need to put enough pellets in the hopper so there is no air leakage, maybe 2 cups.
Secondly the door of the stove must be closed.
I assume the vacuum switch is causing the auger to stop, there are a couple reasons this can happen, the first being of course of the pellet hopper is empty, Secondly the reason for the switch is in case the chimney system or the stove chambers begin getting clogged with ash etc. then the flow of air is reduced enough to stop the auger from turning.
There are several things you can check. on the left side of the firebox is the heat exchanger cover plate, you can remove the plate and check the heat exchanger for soot and ash buildup. This will need to be cleaned.
The other thing you can check is if you have a multi meter you can check the actual vacuum switch for continuity.
Please try the cleaning then get back to me if you have any questions.
Thanks for using JA.
Still not working. Everything seems clean but no pellet feeding. exhaust blower is working fine.
