RE: condenser fan motor replacement - HoosierDaddy - 06-15-2018
I'm looking for another condenser blower motor. I'm thinking of replacing the whole blower. Can anybody tell me what the CFM rating on the blower is?

Another possible option would be to mount a couple 12v radiator fans on the coils and then use a relay to turn them on and off. I'm not sure what the noise level would be.

I got one from Graimger. It was not a direct match. Old one was sealed & oil filled. Replacement was open & air cooled. Shaft also had to be cut down in length. But is has been working great.

ccjohnson, Would you have a part #?

Sorry I don't have part number. The AC guy I had work on the unit in Phx called & talked to someone at Newell. Then he took old motor for measurements on housing & shaft dia etc. to get a new motor from Grainger. As my memory serves me he had to also get a "belly band" to go around the motor to get it to mount in the condenser housing.

Thx CC, I searched and found that thread on NG. Another Guru suggested a Dayton 3RCX7 on that thread. I ordered one from ebay. My concern is that it is only 1/10 hp.

Thx Jon,
I would like to stay with the 115 volt if possible. I am searching for a complete 115 squirrel cage fan that will come close to fitting in the box. Since I don't know the CFM of the original fan I am just trying to match outlet size.
