Burning Hunk

Tonight I fired up the Englander to cure the new paint. A handful of pellets in the burn pot, pellets would fall a few at a time ( like 3 or 4 ) lit and would soon die out as not enough pellets are falling out into the pot. I checked the auger feed motor and its cycling but not much is being delivered ? I have done research and checked youtube for factory settings as well as more efficient burn settings... here is where my issue lies. The 3 buttons on the botton (Low Fuel Feed, Low Burn Air, Air on Temp) wont adjust? When I press them in order I get 6,4,2 Factory settings are 6,4,1 which these settings should be fine . But it seems I need to bump the feed up some or is there maybe a blockage in the auger? I didnt get all the old pellets out of the auger chamber which consisted of a lot of sawdust mixed in with the pellets that were in there. Im planning to pull the auger and check BUT my issue is, I want to adjust the settings but they wont change, When I press the button of the 3 on the bottom the values wont change up or down for any of them. The Heat and Blower values work fine. Any ideas if theres a secret sequence to press the buttons to unlock or is there an issue with the board? Start up, initial burn and shut down all work , just not feeding enough pellets to keep it burning.

I know on mine I need to push both up arrows or both down arrows to get the values to change. I would check to make sure the auger is the correct one for this stove (2.4 RPM). If it is too slow then it won't feed enough.
Also, while I don't have your particular stove, everything I've ever seen from Englander is that the last button, Air on Temp, should always be "1."

Thank you for that info, I will give it a try and see if that works. My question on the auger motor, How do I know what speed it is looking at the old one? Im going to pull it and look into that as well.
I did pop the lid and see the pellets move so I know the motor and auger is rotating as I watched both ( motor spins and auger rotates ) I just dont know how much the auger rotates but the motor spins a few seconds and then pauses a few seconds then repeats. Just wasnt feeding enough pellets to keep it going.
Going to pick up 20 bags of hardwood pellets for $25 later, someone sold a pellet stove and have these sitting... pretty good deal to me LOL

Easiest way to check the auger motor is to put a mark on it and time how long it takes to make 1 revolution. 1 RPM would be 1 revolution in 1 minute hence 2.4 would be almost 2 and 1/2. The spin / pause / spin / pause is normal operation.

Thank you, I pulled the auger out, had a couple pellets jammed ( not sure if the auger is strong enough to break them as it runs or anything like that inside the hopper as I removed what was left in there and seen that. When I pulled the auger out, there was a bunch of sawdust caked up in there around the rubber isolator, so I gave it all a good cleaning, oiled the bearings and put back together. The Values did change when I pressed both up/down buttons so that was great to know it is working correctly. I will check the auger rotation by marking it and see how it performs and I assume the correct setting should have it running close to 2-1/2 rpm ?

First video is what it was set at, second video is after changing the feed value... I havent been out to mark/time it yet, this is from earlier when I pulled it apart and cleaned it, shows some of the caked up sawdust that was in there. I dont know if the previous owner never cleaned it or used really low grade pellets as the hopper was 1/4 full of pellets with equal amounts of sawdust mixed it which was crazy to see.

Sawdust will do it, should have thought of that as I have the same problem with my insert. These single auger stoves seem to get really fussy about fines where my PDV doesn't seem to care. Glad you're making progress!

According to the model number on auger that is a 1 rpm motor. You will have a hard time finding the 2.4 rpm most sites will just sell you a 2 rpm for your stove model.
I just came back to say I just timed it at 1 rpm... So what am I looking for to get a 2.4+ motor ? Is it the actual motor. the gearbox... model/Part number?
 
Ive found the part number in the manual, and found them on amazon from $38-$98.... but all say 2rpm? Is this correct
part number is listed as CU‐047042
 
Is this correct part number is listed as CU‐047042
According to Englander that is the correct part number even though most stay they are 2 rpm motors. If you find one that says 2.4 rpm it most likely is the same part number and is actually a 2 rpm motor. Even if you order directly from Englander. I would stay away from the $38 dollar one unless you are willing to replace in a couple of years.

Yes I agree... we get what we pay for. I know when I got it , the igniter was wrong, I am assuming the previous owner replace the motor as well with the wrong part probly the cause of burning out the igniter originally? At least this is a simple fix.

Ordered the new auger motor, supposed to be in today.... Hopefully this is all that needs to be done, we will see !
The hopper lid has no sort of retainer on it and it springs if you let it just lay back ( where when you close it, it want to stay up about an inch ) Im planning to get one of the "toy box" hinges that go on the side and keeps the lid in position where you let go of it so it doesnt swing back or slam shut, Ive used them before and looks to be a good candidate for this stove since the lid overhangs the sides a bit.
 
Ok, This motor I ordered is listed at a 2rpm motor, but it runs exactly the same as the motor that was on the stove originally, if I lower the feed value it slows and when set to the max it still only turns the auger 1 rpm at the max setting ( heat set at 9 and low feed set at 9 ) at the lower feed setting it makes approximately 1/2 rpm by the mark I put on the auger. Not sure what to do from here as its not feeding enough pellets to keep the fire going.

For grins, make a cheater cord and hook both auger motors directly to a wall outlet (they're 120 volts) and confirm you actually have a 2 RPM motor. That will help narrow down if its a mislabeled motor or a board problem. Just make sure you cover your connections so you don't get lit up.

Englander uses the same controller in most of there stoves, The 25 PAH should be in mode 3 can you check to see if it is. With the stove cooled down unplug and then plug back in the power, then press both the up and down buttons on the blower speed and that will show you what mode the stove is in
 
I checked the original motor it gets 2-1/2rpm so apparently correct. I checked the mode and it is set on 3. The LFF, LBA and AOT are set at 6,4,1 which should be factory.
Since all these are correct apparently, why does the motor kick on for such short cycles with a longer pause ? One or the other is the reason that its not feeding enough pellets. Even if I bump all the values up it still doesnt feed enough at the highest settings??? It starts up and shuts down just fine.
 
I usually clean my hopper about 1-2 times per season to get all the fines out..
I cleaned the entire stove out, used an HVAC brush to get every crack and nook in it. Pulled the covers and cleaned all the ash out , vac'd as well as blown out with compressed air..... it was a dust storm outside for awhile LOL

The auger moves to the programming of the control board chip. On and off by timing. This programming can not be changed. It can be corrupted. Your bottom 3 can allow you to make some tweaks. But nothing can be changed while stove is in start up mode.

Just wondering if theres a way to correct it? The RPM is correct when directly wired, just not feeding enough when running, the pausing or the short cycle is the issue I think? I know someone said Mode 3 which it shows.... but does anyone know what the modes mean ( and possibly the wrong mode ? )
 
With the newer stoves, I don't. I know on the older stoves what A-B-C & D meant but you can't get those any more, at least new. I'm wondering if you have something, fines maybe?, jamming the auger in the tube not allowing it to spin freely, hence not fast enough? When you swapped motors, did you pull the auger or leave it in place?

Auger was pulled, everything is cleaned, I returned the new motor as the old was still good and functioning the same. Auger has some free play so there is no binding anywhere, just the auger when it cycles is so short its not feeding enough pellets. Correct they dont make the board anymore and ebay sells them but I cant see spending that amount on something used and obsolete. I am wondering if the "Mode" setting will change anything as someone said factory is 3 which it is set at.... Im going to go try different modes to see if it changes the cycle of the auger to either feed longer during the cycle or more often.... Ive also sent an email to Englander to see if they can troubleshoot this issue ( maybe something simple? )
 
So as it currently sits, I bought some new hardwood pellets ( claim low ash and hot burn ) Fired up with a few handfull of pellets in the pot, as it died down, you can hear the few pellets drop, they drop s its dying down, flares up then dies down... it keeps burning but the fire is nearly out as the pellets drop and as they ignite, it flares up to a nice fire then almost dies out in a continuous cycle instead of having a nice continuous flame ? Video attached, just to show the cycle it does.... at least it kept burning, but could be better.
Current settings are 6,4,1 Mode 3 , Heat and blower are set at 9 Had it running almost 2 hours like this but not getting a consistent even flame, just this cycle of almost going out and poof over and over...
