I think you mean compressor rather than condenser. Take the panel that covers the controls off the unit. If the clicking noise is the contacter, and it is engaging when the power is turned on, then follow the wires to the compressor, remove the little plastic cover and look for wires that are burnt or otherwise not making contact with the compressor terminals. If the wires are good and you have a volt meter, set it to ohms, TURN OFF THE POWER, remove the wires on the compressor. (remember where C,S,R, goes) touch the meter to any 2 terminals on the compressor. They all 3 should have continuity to each other. No continuity=new compressor. If the contacter is not making the clicking noise when the power is turned on, then you have another problem that I'll need more info. to help.

It could be a number of things. Check breaker panel inside your house for flipped breakers. Check for bad fuses and check your capacitors. But only if you know how to use a multimeter and shut the power off first and understand how to de energize the capacitor. Otherwise call an electrician of hvac professional. Otherwise doing so can be deadly if your are unsure of electricity

I have a whirlpool central air conditioning and the condenser stoped working. what could I expect it to be?

When you say the 'condenser' stopped running - I'm 'assuming' you are talking about the outside unit, and I'm also 'assuming' that when you say it stopped running you mean 'nothing' runs on the outside unit - fan motor OR compressor. The fan motor will drown out the compressor running noise which is a 'low rumbling' sound - often not heard by the layman because of the noise the fan motor puts out.
Assuming you are talking about the outside unit and 'nothing' is running either fan motor or compressor then you might be 'in luck.' Because the most likely reason for the outside unit to be totally off will be a 'blown fuse' or a 'tripped breaker.' The good news is that in 'hot weather,' especially the kind of hot weather that has been present this summer (especially in the south) - blowing a fuse or tripping a breaker is not necessarily an expensive repair.
Indeed, it's not uncommon for a AC unit to blow a fuse (or trip a breaker) on occasion, although it must be noted that doing so is also is sign on something seriously wrong with your AC, i.e. a fan motor breaking down electrically or even a Compressor, both being expensive items to replace.
But, as I said, it's not uncommon for a fuse to blow once in awhile.
I would check my fuses (and breaker) and see if this is what has happened.
If you have fuses (usually located outside close to the condenser) and have no way to check them (you check them with a ohm meter looking for continuity) - then just 'replace' them with new ones. Note: always put 'time delay/dual element' fuses back in - even if the ones that are in there now are 'one time' fuses. 'Time delay' fuses do just what they say they will do - (they hold for just a second or two during that initial start up (of the compressor) without blowing).
If a blown fuse/tripped breaker is your problem then "most" of the time the AC will run ok and you will not have any more problems.
However, if after replacing the fuses and turning the AC back on - the fuse(s) blows instantly, or a short period thereafter (say a few minutes or an hour) then you probably have a problem that is causing it - i.e. the fan motor or compressor is going bad.
Note: one thing that you can fix that might be causing the fuse to blow is a dirty condenser. So, check the condenser coil (think of it like a car's radiator). It 'must' be clean to run properly and when it gets 'really dirty and clogged with dirt it will cause high head pressure and can cause the unit to blow fuses and trip breakers.
Good Luck!

The air condition in my 2006 Lardo 5th wheel keeps throwing the breaker sometime it will run 15 minutes or 4 hours then throw the breaker

You could possibly have a weak set of breakers. If you have access to an amp meter, clamp around on of the wires coming from the breakers so that you can measure the amp draw. If the amp draw of the unit (when running) is lower than the breaker rating, change the breakers.
The other problem could be a stopped up rear coil. This is the part that looks like a small radiator the the hot air blows through on the roof. You will have to take the cover off the unit to see the inside of the coil. Look through the rear fan blade and you will be able to see if the condenser coil is stopped up wit dirt etc. Hope this helps.

I have a Ruud unit at one of my businesses. It has two 220 breakers for heat and one for ac When I turn on the all breakers and then turn the thermostat on it blows the ac breaker. The grass was just...

Sound like you have a short in one of the components. Turn off the breaker that keeps tripping. Using a Multimeter set it to ohms and go from the ground with one lead and each component with the other till you find the shorted component. Once found replace that component. Be careful to ensure that no power is present for this may result in serious injury. On the Heater/AHU it would be most likely your evaporator fan motor. On the outdoor condensing unit it would be most likely your compressor or condenser fan motor. These components electrical wiring would need to be isolated and tested to ground using the ohm meter with NO electrical power present to test for the short.

Were is the reset button on the unit?

Hi, here is the theory on the reset button on Air Conditioners. They reset via the breaker panel box in your house. Check that first before anything else. However if your unit is popping breakers, it is because the rating for the breaker is incorrect, or there is something that needs servicing usually in the outside unit called the condenser. That piece contains the compressor. A faulty compressor and pop the breaker. Or If the condenser fan that blows over the coils of the outside unit stops (common failure) The compressor will overheat and shut down. That may not trip the breaker but the house will get hot anyway. Usual action for this is to replace the condenser fan motor and starting capacitor. Make sure the speed rating and directional rotation for the replacement motor is the same as the motor removed.
There are other reasons why the system won't come one fully. If the wall thermostat is digital and does nothing. including turning on the fan. There will be a small fuse located on the circuit board of the air handler (part of Air Conditioner mounted inside the house. It houses the circulation fan). That fuse could be blown. That one shuts down just about everything.
On air handlers mounted up into the attic crawl space there is an overflow pan. This pan is mounted directly below the air handler. This pan can fill with water when the drain pain contained inside the air handler starts to overflow because the drain system to that is clogged.
There is a "float switch" mounted in the overflow pan wired to the system in such as way as to shut down the entire AC system if that pan fills.
The handling is to clear the obstruction in the Drip Pan inside the air handler. Then remove enough water from the overflow pan and the AC will run as though nothing has happened.
If you have more questions, write to me on this site.
One thing more. The capacitor alone in the Outside condenser unit can fail and that will stop the condenser completely if it is of a "split" design and used for both the compressor and fan. When replacing this unit alone, ALWAYS find the same specification part.
I hope this helps,
Have a Happy New Year,

Ac unit clicks outside but nothing engages fan or compressor on unit furnace still runs for heat setting and fan still blows but ac will not engage just hear a clicking was running for three days this...

Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.

Air Conditioner trips the 110v breaker, only when the outside temp is above 90 degrees. Unit has been checked several time and the circuit board has been replaced, but has fixed the problem of tripping the...

'Breakers' - are tripped because they are exceeding their amp limits.

The 'hotter' it gets outside - the 'harder' your AC has to work - and under normal circumstances this is not a problem - but when you have a fan motor or a compressor that is starting to 'break-down' (electrically) - often the AC's amp draw will exceed the limits of the breaker - thus 'tripping' the breaker.

I would suspect either the fan motor or the compressor is causing your breaker problem.

Eventually - the component (either the fan mtr or compressor) that is 'going bad' will go out completely and your breaker will 'trip' and not stay on when you try to reset it.

At this point you will need a Service Tech to determine which one is bad.

There is a possibility that your condenser coil (the one that blows hot air) is 'dirty' which will also cause a problem similar to the one you have - but it is less likely.

Also - if you've had the AC 're-charged' lately - it's possible you are in a 'over-charged' condition - but again, this is not very likely.

hope this helps.

With ac running cold, blows warm when truck is stopped

I have a dodge 2007 ram 1500...most likely its an RPM issue. The compressor requires a certain RPM to maintain the required pressurized vapor.
