HI300 Fan Unit

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!

Are they permanently lubricated, I wonder?

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 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.

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?

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

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

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?
