Enviro Maxx Feed Rate Trim cannot be adjusted

[Jeffotron77]

Fist time poster hoping someone can help:

I bought a Maxx and it was working fine until tonight. One of the kids shut off the surge protector and now when it is in manual mode it dumps pellets so fast it makes a roaring fire. I think the feed rate trim needs to be adjusted, but the control panel won’t allow me to adjust it.


FEED RATE TRIM BUTTON: Used to change the feed rate trims in 1⁄4 second increments for all feed settings. When this button is pressed, all the light will light up on the Heat Output Indicator except for the one that shows the current setting; the default setting is the number 4 light. To adjust the setting hold the Feed Rate Trim button down and press the Heat Level up or down buttons to adjust the setting. (When I press these buttons together to reduce the trim, nothing happens. The light that is off will not move down.)

Is there another switch somewhere that needs to be flipped to allow the settings to be changed?

Something else?
The unit was working great for about a year until the power was shut off.

Push and hold the feed trim button and then push the heat level up or down button 1 time to adjust. Dont hold both down

Ugggh, that didn’t work either...

You can’t adjust it until the mode light goes solid.

It could also be what was wrong with mine.......,.A bad button on the board.
The surface mount buttons on the daughter board are notoriusly cheap and wear out.
They are very easy to replace if you have basic soldering skills.

Here is an article from member dana.r on how to do it

M55 Cast daughter card

Hi all, Had a great season with my M55. Unfortunately it seems that someone pushed a little too hard this morning on the daughter card and now the power button does not work. I put a meter on it and there is no continuity when depressing the button. The other buttons for the speed are OK...

The M55 has a daughter board. The Maxx only has a control board. If it is burning as hot as you say I don’t think the trim is the problem.

Thanks much! JR was right. I wasn’t waiting for it to have a solid mode light (it was still in start up mode so I couldn’t adjust it). Set the feed rate trim down 2 levels and burning just fine now.

During the startup the Maxx is going to burn hot because of the amount of pellets dropping into the pot. Especially if there’s a delay in ignition.
