POF switch replaced and it still tells me no proof of fire, #3 light blinking. Stove burns perfectly. Starts great, adds corn like it should, then decides there is no fire and goes into shutdown.

Blower fan runs fine on initial startup when it does its little diagnostic thing, but that's the last time it comes on. I have a new blower sitting here, but I don't see the point of installing it if the stove won't keep burning.

High limit switch doesn't seem to need resetting. It doesn't click by the switch at all, but it does click back by the board if I push the button when it's in startup. Once it's in shutdown, the reset does nothing. Is that normal?

Anybody got any ideas? I think I'm gonna try pulling the blower and testing for power during startup. See if that will show me anything.

replaced the blower motor just 'cause I'm running out of ideas. No change. Only two possibilities left. The high limit switch is bad or the new board is junk. Nothing else it can be.

I haven't run into any of these problems yet with mine as I'm still in the second season, but I appreciate you posting updates as I am learning a lot. Wish I could help.

Hi:
Problems tend to be the topics covered in forums. However, I'll share some good news. I've burned between 5 and 6 tons of corn a year for 4 1/2 years now. My only problems came when I did not keep the stove clean.

I've replaced the gaskets, and had to replace the chimney, but the stove has been very well behaved.

I'm interested in a quieter fan. We get used to the noise, but a significantly quieter fan might be worth the price. Has any one made the change to the new style fan mentioned in this thread? Was there a big difference in noise?

Thanks,

John

I did install the new fan just because I didn't have any other parts laying around to try. It's not any quieter, but it only runs for 27 seconds at a time so no real test yet.

Waiting for a high-limit switch to show up. That's the last part left to replace. If that doesn't do it, I guess I need a service call.

Well, the high limit switch never did show. In case you didn't notice, it was ordered over a year ago. Gave up on corn burner and started burning regular old firewood. I have 30 year old "loongwood" dual fuel furnace so I can burn oil or wood in house. Kicks butt. This is my first year so I didn't know how much I would need...ran a little short. Anyway...fired up the Auburn for first time in over a year tonight. As it was about done going thru its startup I unplugged my vacuum bypass to see what would happen. THE DANG BLOWER FAN KICKED ON JUST LIKE IT SHOULD HAVE ALL ALONG!!!! No idea why. I plugged it back in and the fan quit, unplugged it again and nothing. Now waiting for stove to cool off so I can try a fresh cold start.

No idea what the connection with the vacuum control and blower fan may be but it's something sorta positive anyway.

Trying to download a manual from St Croix's website. Link deadends on me. Tells me to update adobe which I did and every time I click on manual (go) it tells me to update. Blah blah blah. I'm wondering if new control board is wired different than old??? Shouldn't be.

Who knows. A chainsaw is a lot of work, but at least wood burns w/o 47 different blowers, motors, relay, and boards.

When you put the new board on it, did the board come with instructions for setting the fuel choice? They have done away with separate boards for the stoves, one board does both pellet and corn stoves. HOWEVER, you must set the board for what you are burning and if it is a pellet or corn stove.

This may or may not be your problem. Do you have a thermostat hooked up to the stove? Does the on off light blink after start up mode is over?

No, it came with bubblewrap.



There is a set of pins (2 rows of 4 iirc) but no little jumper thingy on any of them. To me that's kinda odd. Don't know what else on it would be selectable.



No



Not until it shuts itself off. For the short time it will do a normal burn, no blinking lights.

On the front of the board, does the slide switch just have the options of just thermostat and manual, or does it also have smartstat?

It has all three and is set to manual, the same setting used on the last one. Is that not correct?
