Condenser fan motor question

[joenuke]

I am trying to find a replacement for a Tempstar unit condenser fan motor. The ratings are 1/4 hp 1.2 A 825 rpm. My question is, is there any leeway in the specs for a replacement motor as I am having trouble locating one with the exact specs. If i get a motor with different ratings what specs can change that would still provide sufficient SCFM through the condensing unit? ie. if i find a 1/4 hp 1.2A at 1100 rpm would that still work?

No!!!! The fan blade assembly is not designed to turn that fast. Get the right motor or you will have problems.

IMO, you are asking about specific technical info that is beyond what we share with homeowners because of liability concerns.

Thanks for the quick response. I found a local parts dealer that has the correct part. I understand the liability bit, but in my opinion i don't see how anyone could hold someone else liable for information gathered on the internet. You should be able to take responsibility for yourself and your actions. I will try to refrain from asking too technical questions in the future though.

It's all spelled out for you in the rules. Your welcome here but please read these rules 1st.

any service company should be able to check the motor and make sure it is the problem and replace it with the correct motor and give you a warranty to go with it

That is an excellent point.

No matter how handy you are, you are very unlikely to get any warranty coverage on a part not installed by by a pro.

The best idea is to find a contractor you like and trust, and use them for all their experience and expertise, so that when a part fails, you have a chance at having that part covered for replacement.

This would seem like a reasonable assumption, it seems like common sense. The problem is that common sense is not common and it seldom makes sense to most people.

In a world where people complain if the coffee is cold, and sue if it is too hot, we as professionals have to err on the side of causion and assume the worst of who is reading what we write.

Fan blades and motors work as a team to move the correct amount of air. The condensing unit is designed for a certain amount of airflow. The fan blade is pitched at a certain degree to load the motor properly while providing correct airflow.
