HI300 Fan Unit

[fatalbie]

My wife called me today and said the fan is making a wierd noise. I checked it when I got home and the left side is making a noise. I assume it is a bearing of some sort. 4 years old, lots of continuous use. I looked in the manual and online and don't see the part number for the fan. I have a couple of local dealers I can work with but they are both closed for the night.
Anyone know:
The part number?
If you can do one side of the fan?
Approx cost of for a new fan?

I consider myself pretty handy and would most likely just change out myself.

Thanks,
Jim

I hope it's not a trend. This thread is recent:

Thanks, velvetfoot!! I didn't get that thread in my search last night. I had just cleaned mine the other day, with a vac. I plan on taking the existing apart to check it, but didn't want to do that without the other part ready to go.

Maybe I should get a spare as well!

910-157P

If you can do one side of the fan?

NO. The blower housing contains both fans & is a sealed unit...

Approx cost of for a new fan?

$118 + for the OEM unit. You may find a generic one for less...

It's fairly easy, only a couple of nuts need to be removed (IIRC), & the wiring should be spade connectors, other than the ground...

Thanks,
Jim

Are they permanently lubricated, I wonder?

If you mean sealed bearings, yes.

 

[velvetfoot]

Yes. I recall reading of people who've lubricated something or other on a pellet stove fan, just was wondering if something like that applied here.

I suppose you can try, but when those sealed bearings fail, the ID wears out of round & the axle shaft wobbles as it turns. Enough wear in the bearing & the axle move so far that the blade start to hit the housing. I just replaced a similar one in the neighbor's house...One side was really floppy & the other side ran smooth...Odd that one side should wear that much faster than the other, but that's usually what happens...

I have an HI300. Once a season or more it makes a noise. I pull it out, clean everything as well as I can, blow it out with compressed air, and oil the motor and bearings by dripping in 3 in 1 oil and spinning it a bit. Good as new.

Yes. Clean it out, oil it, forget it until it happens again in a few months. It's just part of maintenance for me now.

Like I said, you can try. It can't hurt, but once the bearing goes, there's no saving it. You can pretty much tell by feel if the axle shaft is "floppy," the bearing's shot...It should not move from sided to side, up & down or in & out.

Right, if the bearing is shot. I'm just going based on my actually maintaining an HI300 fan for the past 8-9 years- if there's a noise, clean and lube.

Why 3 in 1? Is that the electric motor oil?

& I commend you on your PM. If everybody took the time to clean & oil, I could do a whole lot less typing!

Any good oil will work. Don't use WD40- that is good for what it does, but it's not a long-term lube.

 

[velvetfoot]

Thanks. Perhaps I will do that before it starts squeaking when I clean it in the off season.

 

[fatalbie]

DAKSY and Adios, thanks for the feedback. No noticeable wobble in the axle. I'll give the compressed air and oil a try. Ordering a spare for the inevitable

Hijacking my own thread, I'd like to change the controls to the right side. Is there a kit number for the that?

 

[begreen]

If the bearing is not damaged and there is no oil port on the bearing ends of the armature, you can often carefully use a drill to make a 1/8" oiling hole through the case into the bearing's felt oil pad. Vacuum out any shavings and give it about 10-15 drops of 3 n 1 oil and you should be good to go for another season.

Yes, there's a kit. Look in your install manual. That's where it should be listed. You'll need to match the color...
