Replacing Hydroflame Furnace Blower Motor
Since I have had to replace the blower motor on both of my furnaces, I thought others might be doing the same project. After learning the steps on the first motor, the second one went much faster and easier. This is a job that can be accomplished with minimal tools and should take less than an hour to complete if the steps are followed correctly.



Hope this will be helpful to someone. Good luck.

Ray, you can see the part number on the new motor. 33589. The original owners manual list 3589 but the additional "3" has been added in later years. I bought both motors on EBAY. First one was $86.00 and second one was $62.00. A new motor from PPL is about $120.00.

Happy New Year to you and Anne.

Thank you soooooo much for posting this. I have to tear into my furnace. It worked when I bought the coach but was really noisy. Then over the summer some wasps moved in and I didn't discover them until I was winterizing. Now it fires up and runs for about a minute before it pops the circuit breaker.

It's nice to has some idea of what to expect before heading into a project.

Jim, I'm going to GUESS that yours is an Atwood Hydroflame since they were used in the majority of RV's in that period. But to be sure, just open the outer access door and you should be able to see the manufactures label on the inner cover.

Lenny, I think you need to pull the burner (first the flue) and clean it out. It sounds like the gas is being diverted by crud on the burner front, mud dauber nests a prime candidate.

In any event you should install the mud dauber screen.

Thanks for posting the photos for replacing this motor. These are the best I've seen on the web.

Mine came apart almost this easy except the small combustion fan blade on the right hand side will not come off. The set screw is completely removed. There is no way to pry it off and I don't want to bend the fan.

Anyone else have this problem and get past it?

Thanks!

Solved my own problem. The shaft on the right needed to be cleaned up with some sandpaper and hit with some penetrating oil.

I then held the left shaft with a pair of visegrips and using a huge pair of channelocks, I grabbed the centre hub of the right hand combustion fan and wiggled and tugged for a few minutes.

The fan SLOWLY moved down and off the shaft.

The job would have been very easy if this had slid right off.

the way I remove this type/style fan, and most shaft mounted blades, is...

...penetrating oil for about 1/2 hour - let it soak in good.
...hold the shaft and turn the blades or squirrel cage in a clockwise/counterclockwise rotation.

It is usually much easier to get it to turn that way then it is to try and pry it off down the shaft.
