Enviro empress fs

Hi. New to this. But I have a enviro empress. The convection fan is giving me probs. won't run on low setting but if turn heat output switch up to 2-5 it comes on(and squeaks and has no oil ports). Then when turn back to low 1 it sometimes stays on but usually turns off. I took out cleaned fan blades and everything very well. This is 3rd season and I burn 3-4 tons annually. After reading all I could on other posts I'm not sure if it's the fan,the motor,the pof switch(prob not cuz the stove never shuts down and it does come on when heat output is up), or motherboard. The post saying the windings in the motor failing bit by bit makes most sense. Any help would be great. Don't want to spend. $250 on convection blower if not gonna be the fix I need

Really weird. I was messing with the stove again trying to pin down my problem. Unplugged the fan temp sensor(pof) and that ended up causing an error light on board. So I hit the on/off button and reset it. Then after about 5 mins(start
it popped and the fan is on. Not sure why it's working now or if it will last. Maybe the pof switch just needed a little reset.

Yes I took fan out and cleaned very well. So after last night when it was working(with no squeak) I got up in night and the convection fan wasn't working. I turned heat output up a few notches and it came on. Then i immediately turned back to low and it stayed on. I'm thinking it's the motor on the convection fan itself not getting enough juice on low but I guess it could be control board not sending enough? It also baffles me that without fan going it never overheats and shuts down

Well thanks for the reply. I have a newer control board that looks like that. But the convection fan/motor is not like that. It's the one that someone described as a "squirrelly cage". Tonight I shut it down took out control board, checked out all wiring connections,checked and cleaned vacuum hose then took out convection fan(again). When spinning fan by hand it didn't seem to be spinning as free as I thought it should(spin about 1 1/2 times then stop. Also when in stove I could hear the squeak on the non motor end. And since there are no oil ports on this kind I delicately put a drop of pb blaster at end and stood on end for bit to soak in(and make sure al residue and vapors went away so as to not create a fire hazard) after that it spun much more freely. Then I put back together and it seems to be working fine now and no squeak(knock on wood). My logic seems that at low speeds it was dragging to much and didn't get enough juice to spin and only work when output was turned up and more juice to spin it! Hopefully it it will get me thru the winter and then I can look more into replacing the fan.

Looks like this one! At the end is a red rubber bushing

Oh ok thanks for the clarification on name. I looked a bit. Most are $230-300 range. I'll prob get thru this season and replace over summer. Thanks again!

That's where I put the lube. I wanted to try to pop out the red rubber but not sure if I did I could get it back on! That's exactly where the squeak was. And just the drop of pb blaster made a huge diff. Does that red piece come off easy without ripping?

Yes. That what looks like. I kinda started it. But thought better about(since thermometer says 17 degrees outside). I'll see how it goes and see if I can get just that piece online or maybe the dealer I got from has one somewhere. Thanks for the help. I'll post any updates along the way!

Being new to this forum has been great sod at. Thanks to everyone who has giving advice and help. So cool because I'm a do it yourselfer(I don't charge myself a service call haha) I'm sure I'll be on to pay it forward!

Will do. Thanks a bunch!

I'll keep that stuff in mind. That bit of pb blaster made a huge difference. Running great now. I went to stove shop today to see if they sold just the bushing or any old fans I could nab one from cuz he says they just chuck out the old ones as soon as they replace them. But he hasn't got any empress(size) fans in a while. Of course while I was there someone came in with a smaller fan and swapped out for new 1(only $90 mines $250ish). For now I'm gonna wait till offseason to mess with it anymore and see if I can find an old one to take apart for practice so I don't break this one trying.
