Enviro (ef2) blower motor

[chrisasst]

Well, i think I need a new blower motor. It is making a high pitch squeal. Wheres the cheapest place to get this. Parts unlimited has an aftermarket one for $150... anyplace else?

Have you tried putting a couple of drops of oil
in the 2 D holes . Maybe the bushings are dry ?

yeah i will once it cools down.. i think I need to investigate more, the sound is coming from the exhaust side but when i turn the room blower off, the noise stops...hmm

Yeah I just went through this with my EF2. 2 drops of oil in each of the D holes did the trick, but oddly it took a couple days before it completely quieted down. And yes, the room blower is a ventriloquist. It squeals, but the sound seems to be coming from the exhaust side.

Apparently Fasco recommends(broken link removed to http://www.ebay.com/itm/PELLET-STOVE-SYNTHETIC-BEARING-OIL-PP5400-WHITFIELD-ENVIRO-/151463866187) for their high-temp fans. I bought some, but only after I'd already used plain old 3-in-1 oil. You could also use this version of 3-in1 oil, made especially for electric motors, and it meets the spec required by Enviro for only $3.

I was told before sewing machine oil was good to use?

 

[bcarton]

Dunno, but it's probably fine. 2 drops of any good oil in each of the D-shaped holes is probably better than no oil. A lot of folks use gun oil, and I wish I had thought of that because I have some really nice stuff in the garage in a nice glass bottle with a droppper. Be careful not to over-oil, as the manual says too much is worse than not enough.

 

[chrisasst]

Hmm. Well I don't see any oil ports on the blower motor.
Now what?

 

[bcarton]

They're shown on page 35 of this manual. I don't know why they're not shown in the regular owner's manual, which does advise the owner to oil the ports.

Of course, if at some point an aftermarket blower was installed, you might not have oil ports or they might look different.

 

[chrisasst]

yeah, I dont have those...

 

[bcarton]

Dang. Maybe if you posted a couple photos of your motor some of the local motor experts could help.

 

[chrisasst]

hang on, I guess i will have to take the motor completely off they may be on the bottom...

 

[bcarton]

You might want to have a new gasket on hand before you do that. Just use a small mirror to see if you can locate them.

 

[chrisasst]

took it off, the holes were on the bottom.. put some oil in it.. turned it on before putting it back together, noise appears to be gone. Guess I will see after I put it back together..

 

[chrisasst]

Well, the noise is still there. Guess I will need to replace the motor.. Question though:
My current motor has a white connecting plug, that leads to the female disconnects. the picture i am seeing for new motors only have the female disconnects, will this work ok? If picture is need I will post one later..

 

[bcarton]

Whatever motor you buy should plug compatible to your wiring harness, unless thing were modified in the past. Maybe the photo would help.

This is what is there

 

[bcarton]

That's not what I have. What you're holding in your hand looks like an adapter that is plugged into the wiring harness. You probably have an aftermarket fan, and that adapter allowed the installer to connect that fan to your wiring harness. If you remove that adapter your new fan "should" connect into those two white boxes in the lower left. Those blue and purple connectors should be the same type you're seeing on the replacement. Explains why your oil ports weren't oriented so you could reach them with the fan installed.

Well I put on another convection motor, I think it was the original one that came out of the stove.. Runs good so far, however, now if I turn the blower off, the exhaust motor is kind of making a slight scrapping/grinding noise..
Combustion motors have no oil ports correct?

Are aftermarket combustion blowers ok to use? $100 cheaper

I'm in the process of rebuilding mine right now. Just waiting to get the ambition up to run in to town to get the bearings.

I dont think I am that mechanically inclined

The worst part is getting the plastic squirrel cage fans off...takes a bit of patience!!
