Got up this morning and checked the temps in the stove. It was on 5 but giving out heat equal to 4. Wiggled the knob and it went up to 5. So there's the problem. Not sure if it's the knob or the computer. The boards a year old, the new updated one.
Not even an hour later, it's back down to putting out heat levels of 4.
 
Get a can of this, a bit pricy but the best…spray it on the pots and work them back and forth, hasn’t failed me yet

CRC electronic cleaner is better to clean, De-oxit is a lubricant. Be carfull if you use De-Oxit it is possible to soften the carbon track the wiper rides on. Which could ruin the potentiometer.

I'm guessing I'll have to pop the board out and spray on the back, seeing as there's no access from the front.
 
I'm still messing with this thing. When I open the door should the status light go out, I understand that it stops feeding because of the vacuum leak. Also it increases the running temperature for a period of time. This afternoon it gave me 3f as it appeared by looking at it had turned itself down. This was running on 5, I clean the extra ash out of it a couple times a day and have noticed the temps increase, then fade. This is what I'm calling going to sleep. Same thing I notice in the mornings. This also appears to be the cause of the lower then normal temperatures I'm getting. Not necessarily a dirty contacts on the temp knob. I've been monitoring the temps inside and they're better then before but still down about 20f except after opening the door. And finally this experiment was based on a setting of 5. Normal is roughly 430 degress, it went every where from 385 to 420. I only got the 420 after opening the door and letting it wake up
385 is normal for a setting of 4.

Still pounding my head against the wall.
