I picked up a used Fahrenheit Endurance Furnace last fall. I think it is only about 5 years old. In general it works fairly well however occasionally it go into a pot change mode? It works fine for a few days and sometime during the night it puts the message pot change on the display, Sometimes it will leave the upper plate extended and the fire is burning on top of that instead of down in the pot and sometimes it just displays pot change on the display and everything is working normally. Anyone have any ideas what is causing this?
Don't have the same model as yours but sounds like it's starting to stick. Lube the Auto push-arms will good. Make sure no parts of the burnpot is jamming when doing the cleaning, hopefully no one touched the adjustments of the push-arms.
I think it has to do with the auto clean, however I wasn't sure if it was Mechanical or electrical in nature, The fire pot is getting cracked and it possibly could warp an edge up when it gets hot and obstruct the ash pusher. I lubed the push arms when I installed it, I have burned about a ton of corn since so it certainly wouldn't hurt them if I grease them again. Thanks for the input. What makes this hard for me to trouble shoot is that it only does this occasionally. I would think that if is an adjustment problem it would do it every time it cleans however I have been wrong before.
Sounds like it might be starting to fail on you, the burnpot assembly that is. Which revision # is the burnpot (g,h, etc...,)
My plan is to build a new pot for it this summer so I think it will hold out for the rest of the season. Seen pictures of some in worse shape than mine. I don't know the revision on the burn pot however the serial number of the furnace is 3123 I didn't get any documentation with the furnace so I'm sort of in the dark on the technical aspects of it. We are close to the half way mark for me to burn corn, I normally run the corn furnace Dec. Jan. and Feb. then we switch over to a pellet burner in the living room and when it approaches 40 Degrees the Heat Pump takes over. The pot change issue comes up about once a week, I have started adding some pellets with the corn and that seems to work better, the clinkers aren't nearly so hard. I was hoping someone here had some experience with what is happening, apparently this is not a common thing with this furnace. As a side note I got to watch it go thru a clean cycle today, that sure works pretty slick, dump some corn on a plate get it lit, push out the old and drop the lit corn down and it's good to go until the next cycle. I'm also enjoying the auto ignition. I had a St Croix scf 050 before a decent furnace but no auto ignition.
I wish I had the Auto light model too. Hard to run on low at times, just makes me do a cleaning sooner.
That is completely normal. If running on Premium Pellet for the Fuel it will do a Pot Change every 10-11 hrs. This is to keep the pot free of ash. Nothing is wrong with your stove. It's just doing its job
At times it would go into the pot change routine and go out. I have backup heat so it's not the end of the world although backup heat is 60 degrees so it feels chilly in the house at that temperature. When it was doing the pot change routine and going out, I had it set on Corn. I changed it to LM Corn and it hasn't lost flame since. Also added more pellets to the corn, we mix 20 lbs in about 50 gallons now. We used to use about 10 lbs of pellets in 50 gallons of corn. Also we are running on level 4 now instead of level 3 I might leave the heat level there, If it's working don't fix it is my motto. I suspect that I had it set wrong for the fuel we are burning.
I have not burned much corn this year other than a bushel or so that a guy gave me to try and I got a lot of moisture on the hopper lid again the same as last year. I have been burning a 50/50 mix of pellets and rye seed this year with good results. I am switching over to straight rye seed today but my guide does not list rye seed at all. Matt told me last winter that they had not tested using rye at all so it was trial and error for me. I would wonder what setting to use, would it compare to low grade pellets, wheat, corn ??????? I burned about 200 lbs last year and had it on the wheat setting but it was not a long enough burn to really tell. Does anyone have any suggestions at all as to what setting. Thanks Old Fart
Wheat/grain? Might be high ash fuel but mine says Fast Dump so more Auto clean cycles. Watch out for more ash cakes so more ash pan cleanings.
The fuel setting changes how often the furnace goes into a pot change. On low moisture corn it's probably going to do a Pot Change every couple hrs. Premium Pellet has the longest running time inbetween pot changes, but as I said above its only 10-11 hours. Never had my furnace die during a pot change, but I've also only burned a little corn (straight once for a full hopper) and it was mainly mixed 50/50. I'd suspect that had something to do with it going out. Corn is much harder to ignite. So if the fuel on top of the reburn plate didn't have sufficient coals? It would probably go out once dropped into the main pot.
I had a similar issue. The top plate would stick and overflowed with pellets since it couldn't retract. I ended up buying a new burn pot assembly and top plate. No issues since and I've burned about a ton and a half so far this winter.
I suspect that was my issue.. By adding more pellets with the corn and changing the settings to LMCorn it hasn't gone out since. That is exactly what mine was doing, overflowing the pot with the top plate extended and smothering the fire. Also think that part of it is a learning curve with this furnace to get things adjusted correctly. Thx for the input.
