I need to replace my 1/4 HP 230v 1075 RPM outside condenser fan motor.
The current motor is a FASCO, but I can't find a FASCO dealer near me
who sells to the public.
I can get either a GE or an A.O. Smith replacement for about the same
Is one of these brands any better than the other.
BER, while a useful end-to-end metric of a signal, is NOT the appropriate
measurement to be making here - modulation fidelity is.
Yes - a high BER will cause your signal to fall on its face. But what causes
a high BER? It is the radio's inability to distinguish between symbols. And
what is the measurement of how "hard" symbols are to distinguish? Modulation
fidelity. You will see pretty much the same BER for a 10% modulation
fidelity error as you will for a 0.7% error, but if you see a 10% MFE you
can know the system is NOT performing well - you have lost most of your
margin for decode, and any increase at all in the distortion of the signal
will start causing errors.
Think of it as the difference between SINAD and intelligibility - you can
have a 20 dB SINAD or a 12 dB SINAD, and still understand what the other guy
is saying 100% - but if you are at a 12 dB SINAD coming out of the repeater,
any additional noise is going to start causing a whole lot of "What did you
say? Say again?" traffic.
The advantage of regenerating the digital signal, even if you don't apply
the forward error correction at that point, is that you can go from a 10%
MFE to a 0.7% MFE, and thus improve the odds of correctly decoding the
AND, if you then apply the FEC to the signal, you can further clean it up,
so that you can once again pick up bit errors without the radio being unable
From MOL Astro25 Readme file:

-Quik Call II Encode/Decode
-In-Call Alert Operation for ASTRO, MDC, QCII, DTMF and Trunking
-'Failsoft Connect Tone'
-MDC Emergency Alarm Indication
-Smart Rugged Battery for the XTS 2500 and XTS 1500 radios
-Rotary Switch Lock for Channels

New CPS features supported:
==========================- The CPS is now capable of upgrading the PR 1500 and the MT 1500 radios
- The CPS is now capable of upgrading from rebanded XTS models to the
traditional APCO 25 capable XTS models using FLASHport. An XTS 1500 RB model
can be upgraded to a
traditional XTS 1500 model and an XTS 2500 RB model can be upgraded to a
traditional XTS 2500 model.
Please note that a new FLASHkey will be needed for this operation.
-Please note that new field 'Failsoft Connect Tone' can only be Advance
System Key protected if 'Connect Tone' is also protected. Specific
protection just for this field is not supported.
Looks like that's it.
Well, I figured the O.P. had as much use for that info, as any possible
answer to his original question. I was was right, as he actually admitted
"I'm sorry, but I don't understand what you said" after someone gave him a
perfectly reasonable answer.
What I don't understand is why he asked his original question about motors
when is actually dealing with a defective thermostat. What's even better is
he's sitting in 91 degree, 75% percent humidity weather (HGX, Sunday, and he
probably went "shopping" Monday morning) with no AC looking for someone else
to flip a coin as to which is better to buy from - India, or Mexico.
I wonder why he thinks he needs to go motor shopping? I guess it's because
he hears no noise when goes outside. See.... If you had that real expensive
digital thermostat option, you might figure out that you forgot to pay the
electric bill. But, then, most of them Ho Moaner stats have batteries, so
that might not help much either. (Gee, the display still works, so the power
MUST be on!)

If you had been in teh business for any length of time,
you'd know they were referred to as "Generally Defective".
And "Westinghouse" was often referred to as "Worstinghouse".
Of that, you can be sure. :-)
As I recall, the GE motor division was 'acquired' by Regal-Beloit Corp.
~2004. They've been pushing this ECM crap ever since, and have
established a large manufacturing presence in India and China. Not
surprising, I guess.
A.O manufactures a lot of their motors in... I think... Ohio... and
Mexico. They are, for the most part, built to cheap OEM specs. A A.O.
would work fine, but it won't last 5 years, IMO.
On a outdoor unit, I'd put a Baldor BB motor there.
Here's the way to find a motor. Go to
http://www.baldor.com/pdf/NEMA_chart_04.pdf . This is a NEMA reference
chart. You are probably looking for a 48 or 56 frame. When that's
figured out (by measuring), then examine shaft length and the size of
You'll find that Baldor makes a motor for just about any application.
Or... you can pay a contractor to find one for you.
i got a call last year to a local ice skating rink (ammonia system). their
cooling tower was going through GE fan motors every 3-4 months and for some
reason nobody could figure out why. they had reached the conclusion that
"GE was junk". 10 minutes later i found the real problem......they were
using vented motors on a cooling tower. i wrestled a sealed dayton up the
ladder (well over 100 pound motor) and all has been well ever since. in
general however, i do agree that GE motors are not my first choice.
