This is my second year with my cab 50 everything worked great up till now. The stove will start up but once the blower kicks on it stops feeding pellets to the pot, but if i take off the side panel it will run fine.... We cleaned everything even tried a new vacuum switch. I even took the washer off the door handle to make sure the door seal is tight. We can't figure it out? Any help will be appreciated...
Cab 50 Wont run unless i take side panel off?

Ash pan area is all clean i blew threw the bottom to make sure nothing was stoping air from passing threw and my ash pan door doesn't have a gasket on it..... There is no OAK installed but i think thats my next thing I'm going to look into trying i guess.
broken wire maybe? Modern cheap azzed conductors have a bad habit of breaking under the insulation....
Sounds like maybe the hopper lid finally closes enough to get that little magnet close enough to close the hopper lid switch.
The hopper switch is located in a similar location and is activated by a magnet attached to the Hopper Lid.
From page 9 of the manual there are pictures as well.
lights on control box are green to start then it turns red, I out my switch on med and the system will run but as soon as i put the system on high it stops feeding pellets, also we hooked up an outside air intake to try and see if that would help but no go yet.
What have you got for a flame height when the stove is on medium?
And please tell us what you have done in the way of cleaning the stove on both the combustion side and the convection side.
Yes I'm a grumpy ole pita but I'm trying to rule out the normal culprits which boil down to crud in the works.
There is an auto reset fuel interrupter in the Quad system and I suspect this is true with the CABs (but haven't read enough about the CABs to have much stick in the memory department). That system reacts to heat when it senses a possible over fire situation it stops pellet feed. So anything in that snap disc circuit that causes it to open up will stop the feed. Then we have those capacitors in the auger circuit that could enter into the act, the auger systems have been known to run backwards, stop, or run in the correct direction that changes on each feed cycle. Haven't heard of them being triggered in the manner you are talking about.
We also have SidecarFlip's comment on wiring.
We have seen loose connections and poor contact on control box connectors before.
Please don't play with any of the control system with the stove plugged in.

Feeling the Heat
We had a similar issue and our fix was to change out the vent cap. Check to see if your vent cap isn't obstructed. I usually tap all the ash off when I clean out the vent.
So as of now we noticed that my stove was burning the pellets but leaving a lot of black soot on the walls and on my dads unit his stove is burning the pellets but all his inside was greyish white. So i got the stove to starting burning better and made my walls inside look white as well. So after that i cleaned in behind the panels to where the exhaust all goes and i ran the stove all day yesterday on High with no issues and no panels taken off. Now i just come home and the stove was running on High but what its doing now is feeding pellets, lighting up, then the fan starts blowing, then will feed pellets so i will have a nice flame then it stops feeding pellets till the flame is gone and then starts feeding pellets... So its a constant flame up, flame down or gone then flame up and so on.... With the stove on medium the flame hight is about 3 inches above the pot.
As I'm sitting here with stove on medium its kinda doing the same thing flame up flame down flame up flame down.... So ruffly running 3 inches above the pot to the flame being same height as thermocouple
Ok
Now that the stove system is somewhat clean check the flame height against what is in the stove manual under flame height adjustment.
You likely need to do further cleaning.
To do the cleaning you follow the exhaust systems air pathway and and clean it all the way to and including the vent termination.
The pathway starts just above the burn pot, you'll need a combustion blower gasket because you need to remove the blower's fan assembly from the cavity it sits in and will likely destroy the gasket unless you are very careful.

I've adjusted the feed rod thats inside the pellet box. It was running wide open but would creat all that black soot so then i adjusted the feed pellet rod and got it running so that the inside of the stove is white like its burning better. We took off the combustion blower and cleaned all the fins and the cavity it sits in all ready.
Yes from when you take the panels off inside the firebox to the combustion blower and threw all the pipes we cleaned ...... Its just weird that it ran for 24 hrs good then tonight its running like chit again.
The only gasket that i checked and did was the door gasket i took the washer off the handle to make a tighter seal. My Cab 50 doesn't have an ash pan seal.
Back, sorry for the delay, had to give the eyes a rest. Too much screen time.
You said that the soot appears on high burn and then you mentioned the feed adjustment the only setting that the feed adjustment is to be made is on high.
You must also take your time in doing the adjustment because it is going to take several minutes for each adjustment to have an effect on the burn do to the adjusted feed amount has to get up the auger to drop down to the burn pot. It is very easy to over or undershoot on the feed adjustment.
When you overshoot (feed gate open too much) you are headed into the black on the firebox. This is one indicator of a mismatched fuel/air ratio.
I also want to know if you did any work on your house over the summer.

Have you pulled out your combustion blower, as Smokey asked? It sure sounds like you aren't getting enough air through the burn pot.
