230 volt Enviro Windsor Auger Problem

[Marcas]

I live in Ireland and have had an Enviro Windsor stove for 20 years. Everything on the stove works and it will operate for about 30-40 minutes and then go out. I have cleaned everything but the problem persists. The issue appears to be a slow auger motor which is simply not delivering enough pellets. I have three questions:
1. Does this diagnosis seem correct
2. Does anyone know where I could get a replacement 230v auger motor for my stove which is required for European countries. When I look at the company website it would appear that there are no longer any dealers on this side of the Atlantic.
3, Has anyone any suggestions of a workaround if a 230V motor is unavailable.

It could be that the motor is heating up and getting tired, is it the original? Do not know about 230V motors, if no dealer nearby, looks like the internet may be the answer. Good luck with her.

I would start with finding the part number, and then search. The motor only wants to run at it's rated speed, otherwise it will heat up. If it appears to run slow, it could be the gearbox or auger. If you can disconnect the motor and gearbox, you can check each part. My auger will run minimum 10 seconds each minute just to keep a flame. Check how long yours runs.

The Auger motor you want is an EF 001-220v. I suspect you have a different problem!
When the auger stops, is there still a flame in the burn pot? I believe that stove
temperature control is variable, using a dial. If so, at what position is the pointer .
Past the 50% line (or half way. Have you removed the low-temp switch and cleaned it ?
I have a feeling that you are running the stove cool enough that the low - temp switch
is not hot enough . That it does not sense a fire . Causing the stove to go into shutdown.
Have you had the auger motor out and pulled the gear cover, cleaned the grease out
and installed new lubricant? Just some things to check

Thanks for the advice. I wanted to listen to any suggestions before taking things apart as this would mean moving it out from its current location. I took the side panel off. On start-up it seems to take the motor about 4.5 minutes to do a complete rotation. Although perhaps I'm mixing the motor up with the gearing in some way. What I was looking at was a kind of collar with an allen fixing in it. Start up seems to work fine but it would appear to run out of pellets some time after the room fan kicks in. I forgot to note what percentage of the time the auger motor is running but will check that. I found a part number on an online manual EF-001-220V. I found one US supplier selling an original part for $386 although it would be considerably more expensive by the time it got to me in Ireland.

Don't buy a new auger motor unless it fails a bench test ect. The motor could be fine. It's best to "jumper it" for testing if required with 220V although it should be done by a qualified person with a proper test plug. As John said it could be a totally different issue.

I would check the exhaust temp sensor; it's easy to get at from the left panel. Ash is a super
insulator, and the timing for it to see a fire is about the same time the blower comes on.
Take it out, remove any ash (clean it well), reinstall, and start the stove again; see if it improves
Also turn up the heat a little

 

[Marcas]

Thanks for the further suggestions. I will see what I can do and report back.

 

[Marcas]

I took the exhaust sensor out. I removed a layer of carbon deposits with a damp scotchbrite pot scrubber. I then ran the stove for an hour and it stayed lit. Thanks again Johneh for the suggestion. I haven't done anything about taking the auger motor out yet as the stove is recessed into a fireplace and I will need to detach the stovepipe to move it out so that I can get access. Is it simple to open up and replace the grease? This may be a stupid question but I noted that the silver coloured ring turns faster than the brass one, is that correct?

 

[johneh]

The two rings should move together. I have seen what looks like what you are describing.
Reach in with a marker and put a line on each part . I think you will find it is an optical illusion
If they are turning at different speeds, the lock bolt may need to be tightened.

 

[Marcas]

Thanks Johneh for your help on this. I have had another go at fixing it. I took the motor out. Where it connected to the auger the allen screw seemed to have slipped a bit and caused a rough edge. I cleaned this up and put new grease in the gears. Having looked at a youtube video on removing the motor I think the brass bushing shouldn't turn and it isn't now. I thought the problem was fixed but it has come back again. Last night the fire got weaker and eventually went out as the auger stopped feeding enough pellets at its highest setting. The previous night it ran for several hours without an issue. I have ordered up a new brush to sweep out the stove pipe as this hasn't been done in a while and seems to be a potential problem area.

 

[johneh]

There should be a hole the lock bolt goes into on the auger shaft, see picture

 

[Marcas]

Thanks Johneh. I think it may have vibrated out a bit over the years but it is correctly seated now. Something is causing the motor to turn too slowly, either it is tired after being there for 20 years or it is to do with the vent pipe. It seems to be possible to get a motor that will fit from Italy for about 100USD so I might try that after sweeping the stove pipe out.

If you or a friend are qualified, you could extend the motor wires (using rated wires) so you can hook up a voltmeter next to the stove. Then when you do a run, watch the meter. If the motor is getting 220V, but still not turning, then it could be jamming, or the motor is bad. If the motor is getting zero volts when it is not turning, then the motor is good and it is something else causing it. If you have the motor out and the gearbox still attached, you can bench test it (again, you need to hook up 220V, so a qualified person required)

I put the motor back in the stove and it ran well for a couple of hours as shown in the photo. The next few times I tried it it ran for a while and then gradually died. The auger was turning but at the highest setting it wasn't turning fast enough to keep the stove going. I think it should turn 1.5 rotations per minute but it was taking very much longer.

I don't see the pic yet..? one thing about auger motors (the ones that I've seen so far) is that they are very poorly made, and the bearing holders sometime need adjustment. I have seen them jam, and just the slightest adjustment on a bearing bracket fixed it.

 

[Marcas]

Thanks Whitenuckler. There is a photo of the stove running above posted on Wednesday. I had some difficulty extracting the auger from the motor as the flat part of the motor where the auger attaches had got some burrs on it. I filed these off and everything seemed fine after that. If sweeping out the stove pipe doesn't work will try testing the motor with zero load on it before buying a new one.

 

[Marcas]

I have cleaned the stove pipe and don't think there were any blockages. I have taken the auger motor out and would like to bench test it. It has an earth wire attached plus white and yellow wires. I'm not clear which of these is live and which is neutral, can anyone advise please.

Yellow would be live, and white neutral. Here the neutrals are white and grounded. Then we have maybe black or red as the hot.

 

[Marcas]

Many thanks

 

[johneh]

Just came to mind that stove uses bushings for the auger. Does it turn freely by hand?
Maybe pull it and put a little lithium grease on the shaft where the bushings ride.

 

[Marcas]

Thanks, it does revolve easily.
I took out the auger motor and made up to a test cable. It is supposed to revolve at 1 RPM and it was a little faster than that. I put it back in and kept it connected to the test wire and it turned the auger at the same speed. It appears that I can rule out a stove pipe blockage and a bad motor. I will try some pellets in it and see if it is sorted but I suspect there is something else I'm missing.

 

[johneh]

Can you send me a photo of your control board?

 

[Marcas]

Hope this helps. The stove ran great for about 40 minutes this evening and then the auger motor stopped turning despite the auger light still flashing as if the motor was running every few seconds. No fault codes showing.

 

[johneh]

Ok you have a DHC 2000 control board
Page 9 of this manual tells you how to adjust the auger trim

You can also try adjusting the heat level a little higher
