I have some question:

1. Is the location of your outdoor unit have no any obstruction? Means that air out of the outdoor is not short cycling into the air in.
2. Did you check the current reading during start up of the unit? Is it like the name plate current reading?
3. Did you check your voltage reading in your unit during operation? It should be plus or minus 10 percent in the unit voltage rating.
4. Are all of your terminal clips and terminals are tight.

During unit operation you should get the fallowing data. So that we can know what really is the problem.

Suction press-
Disc. press-
current reading (actual)-
current reading (name plate)-
Voltage reading (during operation)-
outdoor air out temp.-
outdoor air in temp.-
Ambient temp.-

My AO35h model carriern split air con compressor triping and not cool proper same time out door fan working

Check volts and amps at the compressor, check the contactor points, make sure they are not burnt or stuck, check the run capacitor, start capacitor and relay, if you have them. Make sure the wires are good, not loose, broken, frayed or discolored from being hot. If the capacitors and relay are good or within ratings, then the compressor is probably your issue.

I just replaced the fan and the capastitor on an outside air conditioner unit yesterday. Today it was blowing so cold I increased the temp. on the thermostat. Now it is blowing 77 degrees air instead of...

The air being blown at the condensing unit isn't the air that blows inside. I seriously doubt what you said about it getting so cold. I believe that the wires to the capacitor were improperly installed, and your compressor isn't operating. Don't confuse the outdoor fan operation with compressor operation (they both share the same contactor as a switch). On the capacitor, the brown wire connects to fan, compressor attaches to "HERM" common attaches to the contactor. I didn't mention the colors of the common or compressor wires because they differ among manufacturers.

Replacing the Contactor on my Rudd AC model uaka-037jaz. I got a Dayton 2utl4 contator for a replacement. I need to know which wires connect to what location. I hooked it up with the 2 thermostat wires...

On this unit wiring is very basic, line in wires to the two lugs on the bottom, common as refered to is always black wire which goes to the compressor and the fan motor, red to adjacent lug of the contactor which then one goes to the capacitor and one to the compressor and one to the outdoor fan motor. One wire usually yellow from capacitor to start winding of compressor marked on the capacitor as herm, and a brown wire to the fan motor from the capacitor. The side connectors as you know go to the 24v control coil. The reason as to the fuse going out could be due to loose connections in the disconnect box or a short in the wiring at the compressor, fan motor or capacitor, and worst case a shorted compressor internally. Recommend having the system checked with the proper equipment to include an ohm meter with uf reading ability.

I assume that is a 240 volt unit. If you have a volt meter, check for power across the contactor . If it is a 240 volt unit you should get 240volts on both sides of the contactor. If you DO have voltage across the contactor (after it closes) you need to try and get to the compressor where the wires connect to it. There should also be 240 volts at the compressor terminals marked "C" and "R". If you have power at the compressor between C and R and the compressor is still not even trying to start, the compressor windings are open. Here is really what any tech will need to know to really help you:
(1) Is the fan motor running?
(2) what voltage is the unit?
(3) is the compressor humming or trying to start?
(4) do you have the proper voltage at the unit?

If you can answer these questions and you want to email me, do so and I will step you thru it. Be very careful , as you are dealing with high voltage.

Carrier out side unit not coming on. Removed the contactor waited 1/2 hour reinserted and only heard a click. Any idea's? Still blowing cool not cold air. thanks!

Most likely the run capacitor has failed or there is a problem with a hot terminal on the compressor. You did not include a model number. However, if you open the unit AFTER making sure the main CB is switched off the capacitors are usually under the top shroud not far from the contactor relay.

Also take a hard look at the contactor itself. Sometimes they get hot contact that will appear BLACK as you look at it. There is a spring that holds the contact points in place. You can very carefully remove the spring with a jewelers screwdriver and then lift the contacts off of the contactor. Just sand them off with 120 grit sand paper if you see they need attention and then reinstall the contact points on the top of the contactor.

Follow the wires from the Cap to the compressor. You will note a plastic cap on the top of the compressor. Remove the clip or nut and lift off the plastic cap. Inspect the 3 terminals on the top of the compressor and the wires. Usually what happens is that one of the terminals gets loose and then becomes hot which results in either a burned terminal or wire. You will probably have to remove a shield gain access to the top of the compressor.

Thanks for choosing FixYa.

Goodman ckl49-1 fan doesn't work after a really bad storm.

It is possible that the rain has washed out the bearings and the motor is frozen up. You may need to replace the motor. Also you don't need to put more oil in the compressor. The compressor comes with oil already sealed in it and it does not need to be changed or any more oil added to it.

Have a janitrol cple24. Replaced both outdoor fuses and contactor and still have buzzing. What else could be the problem?

does the unit work properly and still buzz? loose mounting screws on a contactor will create a buzzing noise
is the compressor humming -try a hard start capacitor/boost capacitor
is there 220v at the contactor

Outside unit won't turn on. I can hear the power

Could be anything from a bad contactor to a blown capacitor. Fan motor might have failed causing the compressor to quit in overload (MORE)

Ok you have to trace the wires on down to what terminals they go to on the fan and especially the compressor. Usually you cant go by colors but always by the names on terminals and the like.

The capacitor has labels like (C or Com) (Fan or F) and (Comp or Herm). The compressor has terminals like (Com or C) (S or start) and (R or Run)

Write all the colors down on the compressor and the terminals that correspond to the colors.

Then do the same for what you can trace to the fan motor (usually there are only 1 or 2 going to the fan motor) If it just goes into the fan motor write down all the colors that go from the capacitor to the fan motor. The other wires from your description haven't been chewed or removed correct? If this answer is other than correct we have another step to perform.
