Yesterday, the actual temperature got to 110 degrees F. and my 6year old a/c
decided to go on the blink.
First, I changed the filters, they were a little past due. Then, I checked
the thermostat, and found that the batteries were corroded, but still was
working. Cleaned up that mess and installed fresh batteries. Then I reset
the breaker. None of this worked. First sign of daylight, I took the
compressor apart and found filthy with Willow seeds. Cleaned all that up,
but still the compressor doesn't work.
It's a Lennox, if that matters. Any suggestions?
Are you certain it's getting power? I know you reset the breaker at the
panel. I have a breaker at the 200-Amp service panel and also a
disconnect breaker on the side of the house adjacent to the compressor.
Both have to be passing current for the system to work. Some of the
outside boxed (depending on your electrician, etc) will have a breaker,
others may have a cartridge fuse.
Last but not least, let's not forget that circuit breakers can crap out
after time. Gotta make sure you have current on both phases of the 240v
at the compressor.
Only time I had a problem in recent memory was when some damn chipmunks
got into the compressor housing and decided that the insulation on the
control wiring was delicious and the small gauge copper wire was just
dandy to gnaw through.
My guess is it's a capacitor. Would only cost you $30 or less to
swap them out; $250 or so if a pro/tech does it. You have to
learn how to discharge a possibly charged capacitor before you do
it. Good luck!
Well Genius... Where does a citizen purchase the needed capacitor
without an account? They are not available just anywhere other then
Wholesale Dealers. Most Service companies purchase them by the case and
it takes a number of cases to cover all values that are made. Service
call is about $120...Capacitor is about $45 and is usually a dual for
fan also...Labor about $20...Plus whatever tax you area requires.

I didn't have any trouble locating the ones I needed in
Indianapolis, and I didn't even have to go to Granger (who I
suppose has them all at twice the price). Just check the Yellow

I had "half" of a dual go out, and replaced the half I needed for
cheap. The replacements don't have to be "Lennox" branded, they
just need to be the right size (or a little bigger). Like I
suggested, the OP could swap out the capacitors and be out less
than half the price of a service call. It doesn't take a
"genius". I bought a voltage tester that tests capacitors too
for about $60.
There are some on Usenet who would discourage DIY's. I am just
the opposite. In my area, it cost $250 to have a capacitor
replaced. Not all contractors are as reasonable as the ones in
Labor about $20...Plus whatever tax
You can buy capacitors on ebay from US places so shipping is only a few
days for $ 20 or less for most.
Several years ago my AC quit. Called the man and he replaced the
capacitor in about 10 minuits or so. He worked for a larger company .
When I called they said the service call would be about $ 90 . Fair
enough. Then that $ 20 capacitor cost me close to $ 300 for him to
install it. That company had about 5 level of service and each one had
a price. Mine was the least expensive. I would not have minded him
charging $ 50 for the capacitor. In fact he asked me what I though it
would cost and I told him probably about $ 25 to him, but $ 50 to me.
He was very friendly and knew a lot and he told me to get a capacitor
and a relay as those 2 items usually go out. I looked on ebay and
ordered one of each for less than $ 20 each. A few years later the AC
quit again. I replaced the capacitor and all was well. Ordered another
off ebay for a spare.
I would think most any shop that sells and rebuilds motors would sell
you a capacitor for less than $ 50. My well pump quit and it was the
start points . Took them to a motor shop and the name tag data of the
motor. The man came back with a new one and sold it to me without any
Mos likely if a CC Dickson suply place is near you , you can get one
there without an account. I bought a few bearings for my AC air handler
unit from them without an account.
It may or may not be the capacitor, however,
You might want to get off your high horse there pardner.
There's a new thing out there called the internet, with a dozen
companies ready to sell you the capacitor you need for your air
conditioner. Even Ebay and Amazon have the capacitor you may need.
Getting the right part number is the proper start.
Here's a random search on Ebay for Compressor/Fan capacitor.
Just the fan section of the dual capacitor on my compressor crapped
out, I subbed in a cap from a squirrel cage fan I had in my shed until
the proper part I order off the internet arrived.
Eat shit amdx. Nobody said that it was the capacitor and the owner
wanted immediate cooling. As per your many many fucked up past postings,
You seem destined to shoot your face off in a Pro group. Take your
babble back to the Homeowners. Maybe you can get some of them hurt or
worse with bad advice. By the way, my business covers parts of 3 states

Blink is not a carefully defined word.
You say what you did but don't say what the problem is.
Was the fan in the house running?
A hint at the problem. How do you know it doesn't work? Did y ou
turn off the power at the switch you can see from the compressor and
forget to turn it back on? When you first turn the power back on,
with your hand on the compressor (the actual compressor, the roundish
thing bigger than a softball and smaller than a soccer ball. Not the
box you took apart) does the compressor vibrate at all? How long does
it continue to hum/vibrate? (I don't mean shake visibly. Just the kind
of internal vibration you can feel with your fingers.
Does the fan inside the comparessor box run? Does it stop later? How
long does it run?

If the compressor is overheating, a few seconds might not be enough time
for the internal switch to reset. Others here know more about that.
Is this the main breaker box? If so, there is usually** another box
that is in sight of the person working on the compressor, for his
protection, so that he can turn off the power and no one can turn it on
without his seeing them. **I think this has been required for more
than 40 years in the US, including when upgrading old AC.
So you're judging either by the noise or by the fan's lack of motion?
But didn't it take a minute to get from the box in the garage to the
So it sounds like the breaker is tripping. Otherwise one of the two
should run, even if the other is broken.
You probably have two different circuit breakers, one for the part
inside the house and one for the 220volt part outside the house. Are
they both On?
Does the 220 volt part trip soon after it's turned on. TWo ways to
check this. 1) If the 220 breaker was tripped, open the switch outside
the house, go inside and turn on the 110 and the 220, go outside and
while watching and listening and even touching, turn the sw
2) Also you can test by turning off the 110 part (single breaker iirc)
turning on the 220, and then
Do you have cartridge fuses instead of a 220 volt breaker? They blow
too but don't always look like it.
If you are technically inclined there is a series of videos on U tube by a
HVAC guy that are excellent. I can't recall his channel at this time.
Preview a video and decide if it's in your competency or not.
