P43 Replacment Blowers

[dw06]

I bought a Harman P43 in dec 2010. It has been my only heat since then, and moved with me in 2014. Only thing I've done is cleaning and replaced both door gaskets. This winter both the exhaust and blower motors got noisy. So going to replace both before heating season. Have been soaking the exhaust fan set screw hoping it will come loose haven't tried it yet.
My question is do I replace them with Dayton or Fasco ? Is one better than the other? I look forward to another 10 years of service.

Either one is good, I haven’t heard a bad thing about either. I’ve been a able to get the set screw broke with a good PB-blaster soak on a few of them now.

Good to hear, I've been soaking it with PB for couple weeks here and there. Debating on the distribution blower weather to buy just motor, or buy he whole thing with shield and all.

Just make sure you have the proper size Allen wrench for the set screw and the longer the better. If it was me I’d just get the whole assembly regarding the distribution blower.

The Harman distribution blower motor is balanced with the squirrel cage so best to get the whole unit. Dayton makes it.
The Harman combustion blower is made by Gleason Avery which is a far better motor than Fasco motor.
If you cannot get the set screw out, I just remove the bolts to the motor so I can get the sawzall in with the metal blade and it is out in a jiffy!
Just my 2 cents.

Good info, was wondering how to go about it if I have to cut shaft. Might give set screw a try this weekend. Thanks to all for the help.

Going to do the same thing on my P 43.
Any recommendations on where to get the parts?

I ordered the blowers from them today. Said they will be here on monday the 17th. Also had to get a new fan, got set screw out easy, but fan bent up pretty easy. I still may have to cut shaft since fan isn't moving.I'll soak it couple days and try again.

Got the blowers today, Thanks to Mountain View Hearth Products!! Both blowers look great.
Now for a small problem, one bolt for the combustion blower fell in. I see them for sale, but they have to go in from ack whith no way to reach back there. What do I need to do to fix this? Been thinking about it and am stumped. Any easy fix for this?

Can you post a pic of where it fell in? A small magnet?

This is one of the three studs that the blower is attached to stove with. I think they are installed before the stove is welded shut.
I could use a toggle bolt, would have to drill hole bigger for toggle to fit, then use screw with head cut off so I can use a nut on it.

Oh ok, differed than my P61 then, they come out the front on mine.

Same here
Just reach in the front of the stove and it should be in the big round cutout for the exhaust blower impeller fan. Then just put it back in the hole. All done!

Aw Man, now I feel stupid, didn't know that. I haven't cut the fan off yet as had to wait for a sawzall. Hope to do it tomorrow, so I guess I would have found out then. Thanks for the info, makes me fell much better!
This is why I love this site, always get the answers you need. Thanks to all I'll report back when its up and running.

Not sure a sawsall will get the impeller cut off easily. I used a dremel tool with little cutoff disks to get mine off. I cut slots in the hub of the impeller and pryed them a little with a screwdriver. That loosened the fan up enough to slide it off. Whole thing was done in about 20 minutes.

The sawzall is not for cutting the impeller off. I use the sawzall in the back to cut the blower motor shaft quick & easy after removing the blower nuts to get the blade in up agains the shaft. This method takes less than 5 mins. Time is money$$ in my case$$ LOL

Smooth sailing this morning! Cut shaft in 10 sec, cut wires on old one put connector on plugged in. Did test run ran smooth and right direction. Taped up good and done.
Will take distribution blower off tomorrow install new one. Thanks again for all who helped!!
