Author Central Air Conditioner issue.
Silt

2005-10-25, 3:21 pm

Hi all,

Having a problem with my central air and was hoping someone may have a
guess as to the cause. I plan on having a professional come look at
it, but would like to hear some possible causes to my problem before
someone comes out.

Here's the problem. When I turn on my AC, it starts ok and cool air
is blowing in the house, but after about 10 minutes or so the fan on
the AC unit outside the house stops spinning....yet when you are next
to the AC it still sounds like something is on still. I tested
turning off the AC...waited a bit, turned it back on...and again it
functioned correctly for a little bit then again the fan stopped
spinning.

Any "most likely" causes as to why this happens? Again, I plan on
having someone come look at it, but if it is something along the lines
of "it's most likely a bad relay"....I want to be armed with that
information before someone comes.

Thanks a ton!

It's most likely a bad relay.

it sound like you may have bad fan motor
it seems that it is shutting down on overload
and or bad running capacitor
good luck from Dido

It's most likely a bad relay or something else.

Sounds like you need a new compressor. When the fan stops, it still
makes a humming/buzzing noise. Its not cooling because the compressor
is locking up. Most likely, the compressor is too expensive to replace
so you might as well get prices on a new unit. Then you'll have a
warranty. You might want to think about a new furnace too. Maybe even
a new car...............a house too while you're at it.

The relay isnt bad. The capacitor isnt bad. The compressor isn't bad. The only
new part you need is the condensing fan motor. Typically when replacing a
motor, its a good idea to replace the run cap as well. The existing motor has a
bearing thats going bad. The bearing over heats, the motor over heats, and an
internal switch inside the motor opens and stays open until the motor cools off.
Then it repeats this cycle.

Now, if you want to know the best way to change out this motor, go ahead and
ask.

Thanks for the positive response, it's much appreciated. Nice to see
that even though I may have posted to the wrong group, someone didn't
mind helping.

motor...... kill a good compressor before?

Could be one of several things. At the moment, the likely thing is a motor
problem. Could be dry berrings. Could also be that the condensor needs
cleaning -- retaining heat. That extra heat would not help the fan.

Now, if I was on this job I'd first check the capacitor. Second, would be to
check the run amperage of the fan. Third, would be to oil the fan berrings,
and clean the condensor.

Run test for awhile, see if that helped.

And the XXXXXXX pulled a SWAG out of his butt-hole for you,
based on exactly ZERO information, totally worthless, and he did it so
you would think he was a big man.

Seems to have worked.

Unfortunately, it won't get your AC fixed. It will, however,
cost you a part you don't need if you follow it.

Actually, I saw one time three or four years ago. A bad fan capacitor killed
an otherwise good compressor. I got to replace the condensing unit.

Hint to the original poster: A small problem can become a large problem if
the small problem is ignored. What coulda been a $100 service call turned
into a nice $1250 afternoon's work.

Maybe he can get his insurance to pay for him a new one...or maybe

It is a guess at best but sounds like a bad fan motor or a bad capasitor but
most likely a capasitor.

It does not sound like a bad compressor !

Nope, cant say as I have. In that particular case, the bad cap would have to be
a dual cap. Remember, 99% of what I see is 3 phase. The OP indicated his CF
motor was cutting off after a 10 min run time or so. Bad dual cap? not likely.
remember, the compressor continues to run, according to the OP.

My response was based 100% on what the OP posted, for his particular situation.
Hell yes other scenarios exist that could result in the same symptoms the OP
posted, but my money says its the CF motor that needs to be replaced, along with
its run cap.

Whats .......interesting.......to me is that my response to the OP actually
triggered something that might resemble ON TOPIC.......if you know what I mean.

Naah, it was during compressor season. And the capacitor had a permit. Here
in NYS, the compressors are so over stocked. They run across highways and
smash up people cars. I've seen enough cars totalled by compressors. Heck,
sometimes even if I think some capacitor is out poaching, I don't say
anything. Capacitors got to eat, too, you know. We got some of the best fed
compressors up here. Plenty good eating. Just have to drain the mineral oil,
and hang em and gut the piston out and let em cool over night.

GoFish,
I was referring to a single condenser fan motor run capacitor which has
nothing to do with the compressor's run capacitor.

I agree with Fish on this, Folks. It's a classic thermal motor trip...
coming and going.

As Fish said... other scenarios exist.... but be honest: If you were to
walk up with one exhibiting the same symptoms, what would you think?

BTW, it wouldn't have surprised me if Fish had to the guy in response to
"the best way to replace the motor" would have been to call a repair
guy, anyhow... so don't get your shorts in a knot (-;...

Well sheesh. I see your point.

No, I've never seen it firsthand myself, but can easily see how a bad CF cap
could kill a compressor.

What I see an awful lot of is toasted CF motors. Hundreds of em.

Even if the cap is bad, it's likely that the motor is bad too. Also,
even if the motor was ok before the cap failed, it more than likely
isn't ok anymore. It might run for a while, but the bearings have been
damaged by the overheating and it likely will lock up after you leave
it. I usually explain this to the customer, and the fact that the
compressor could likely fail if this happens. 99 times out of 100 they
give the go ahead to replace the motor. My honesty may cut me out of a
compressor or condenser unit replacement at times, but I sleep well.

That would depend on a lot of things, Chris... like the condenser outlet
temp (as this is a air-over motor), the airflow, etc.

Key here is that (apparently) the motor fires off, comes to speed, and
then stops for no apparent reason.

Of course, you could have a defrost control kicking in, or some other
esoteric reason why the fan quits... but the most likely reason is
thermal overload... which equates to high load (poor airflow, plugged
condenser) or bad bearings in the fan motor, or it's weak, or the blade
is bent, or.... or.... or.....

No, ten minutes is not a benchmark.

This is ReRe

Just stopped by to take a look a this fan problem.. It has a P70AA-118C
installed with a DOB Relay installed and set at, guess what, 10 minutes.
Wasn't a problem before the weather started cooling of because the P70 is
set at 275 with a 75 diff. Now that the temp is dropping a little the
pressure is dropping out the fan and it stays off for a while.

Ok, I give in... I was just screwing with you. But, the scenario could
happen. I suppose I'll "Plonk" myself on this one.

The above here is probley true as you and Gofish was a saying but i still have
still leave in the 1% of the time of a capasitor being very weak or shorted
through & not to frame and the motor high amping and will cut out on high temp.
you can hook up a condenser fan motor and run it but where the capasitor is to
be , you just jump it out with a wire jumper. The motor will run at all most
full speed for a while and then cut out on high temp. this maybe nick picking
but it just seems to me as a possiblity.

get the elevation from to tell the elevation and location of the land. They are

So help me out here in understanding your scenario:

A P70AA-118C is a high-head close-on-high limit.

So... the compressor takes off and, because of low ambient the head
pressure rises closes the P70AA-118C and then activates a delay-on-break
relay that locks the fan out ... until the pressure drops and the
timeout period is expired?

Why would you do that (the time.. ten minutes seems like a lot) in the
absence of other controls to be sure the other side of the equation
doesn't get out of hand?

Jake, I'll let ReRe give you his answer, but generally speaking the p70aa-118c
is a pressure switch that opens on rise and then closes on fall, based on the
differential setting. adjustable close point, adjustable differential. ReRe
was f*cking with us. He threw the 10 min delay-on-break into the mix to
account for the OP's 10 minute scenario.

I use the 118c on computer/phone room units, and set it up to cycle the CF fan
motor, maintaining a head of 180-185 to 225-230. It can be a real XXXXX to set
up in cooler months, as you need to occasionally kill the blower intermittantly
as well until you get things dialed in. If its a hp, you better add a bypass
relay for heat mode.
