I’m having issues with my enviro maxx1, the flame is completely out of control to the point it’s burning up the burn pot.
I do clean it regularly, the feed rates on the lowest setting, the combustion blower is on the second setting. All of a sudden this started. Never had issues with it before and now the flame is up the glass and excessive. Tried changing combustion blower rate and also the air intake…. This affects the ash build up (more and blacker ash) but the fire still rages on. Really not sure what’s else to do and or try at this point.

Is this in manual mode, or are you using a thermostat? Do you have outside air installed? Need Johneh the Enviro guy to see this.

Welcome to the forum
Wild flame with black tips indicates a stove that is due
for a complete cleaning. From air intake to exhaust termination.
Not just a combustion chamber cleaning, but panel removal, all
exhaust passages vacuumed. The combustion blower removed and
cleaned, and the chimney cleaned
Does the stove have an outside air kit? If so, make sure it is also cleaned
nothing is plugging it. Ash, a pellet stove's greatest enemy

I’ll give it a through cleaning again but I don’t know if it the issue. I’ll get back to you after I do this.
 
Have you changed pellet brands? The vent on the left side should allow you to tone it down if need be.

I changed this year, but they are very similar and ran through ton and 1/4 or so before this issue began. I think it was the seal on the plug for the stove pipe clean out, as not much came out when I cleaned it. Now the heat output fan won’t kick up to speed. Stoves running and blowers running but for some reason if the heat output fan is on the highest or the lowest setting it’s running the same speed. It’s the speed it runs when it first turns on and before it gets fully running and kicks into gear, if that makes sense.

So I did and it’s flaming better now. I think the issue wasn’t cleaning but the gasket on the plug for the clean out of the stove pipe had rolled and wasn’t sealing properly.
Flame is much better now, BUT for some reason now the blower won’t kick up to speed. I can toggle the heat output setting and the fan doesn’t change speed if it’s at the high end or the low end. Not sure why it’s doing this now. I’ve never had this issue. Any advice?
 
On normal programming for the Maxx it will only run on high when the stove is set at 3 or more. I have mine on a snap disc that puts it on high when stove is on 1. What is the lt side damper set at?

Do you mean the heat output when you said “3 or more”? I have the heat output set on high, Slide damper is just a hair over half. Flame is about right now and the ash color is much better, lighter, just the blower won’t kick onto high.
Thank you for your responses I sincerely appreciate it.
 
Yes heat #3+
 
so I’ve cleaned the stove deep as possible, I’ve changed pellets, and I’m running the damper wide open. Flame is still way too big. I’ve determined there has to be a feed rate issue. I have it on the lowest setting and it’s still dumping pellets every 2-3 seconds. In the start up the burn pot is mounded, as it burns it gets down to a more manageable level.
To recap:
Feed rate is at 1
Combustion blower is at 2
Damper has been run from half to wide open and it doesn’t seem to make much of a difference either way.
Swept stove pipe, pulled everything out and cleaned the stove, including the exhaust system. Nothing clogged, air moving well.
I do have a professional coming next week but really hoping to figure this out and get the stove back up and running well as it’s been super cold here lately.
I appreciate you guys trying helping me out with this.

Here is a post I found:
Maybe the repairman can check the vacuum and perhaps re-program the feed?
 
Reset your feed rate to 4, which is the default setting
Set the gate at about 50% opon .
All the adjustments should be set with the stove warm
If you have no improvement, maybe the board is faulty.
loose connection on the wiring harness
Double check
NOTE: If the system light is flashing, the Control Board has complete control of the unit. When the unit's system light becomes solid, then control of the unit is given back to the operator.Check the position of the Thermostat slide switch on the Circuit Board
