Unit is approx. 10 yrs old and just stopped working. There is power to the compressor and you can hear it clicking from time to time but it will not start. I read about a Starter Power Pack that is suppose to help start a sluggish compressor. Do you fell that this my problem.

Air conditioner compressor will
not start. When power is applied to the air conditioning outdoor unit
the fan starts, but you hear a sound like the compressor is trying to
start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the
outdoor condenser fan run. The compressor is locked and will not start.
What is happening is the compressor is trying to start, but because the
compressor motor is locked it tries to start for a few seconds and then
because of the high amperage being drawn goes off on internal overload.
The internal overload protects the compressor windings from overheating
and burning up. I see this many times during the start of the air
conditioning season. Some compressors just have a hard time starting
after sitting all winter long. Some compressors are locked up so bad
that I can not start them and must tell my customer that they need a new
compressor . Many times I can get the
compressor started again without having to buy a new compressor by using the device
called, "Super-Boost." I keep two or three of these on the truck. They
have saved many of my customers from having to buy new compressor
It sounds like the capacitor and/or compressor are quitting. Try getting a Start Capacitor of the same uF (I think 35 uF for Commpressor and 5 uF for fan motor) as the one you have, OR get a Start Kit from any AC parts shop for about $10 and hook it up in line with the old capacitor, if you have a two terminal capacitor plug the terminals one, on each end, if you have a 3 terminal called DUAL Capacitor, each terminal is stamped with the words FAN, HERM and the letter C for common, one lead goes in the C terminal and the other one goes on the HERM.
Install it and turn unit ON. Good Luck!! Don't forget to rate this post!!
Do you have an amp meter? and volt meter. Are you sure that the compressor is getting power? The click may simply be a relay closing but no power. Check both sided of the relay. You will need to trace the power and make sure that the compressor is getting power. Then check the amps to see how much power it's pulling.
that sound was the contactor closing, check the outside wires make sure they haven't been cut or ripped off unit. Buy a generic a/c contactor and connect it to the low voltage wires and see if it will click. if so install it the same as the old one after shutting off high voltage. If it doesn't click it is in the wires 90% of the time!
Sounds as if your compressor has locked up. 2 things to do. 1`) get a hard start kit from an a/c supplier compatible with the volts on your system. makie connections to the existing capacitor as directed in the kit. If that doesn't cure problem you need a new compressor
You are being ripped off. The ambient (outdoor) temperature at night is low and therefore proper condensing does not take place causing the refrigerant to pool in the condenser and starving the evaporator. This causes a lower temperature in the evaporator resulting in "freeze up" which is often mistaken for a loss of refrigerant. The proper thing to be done is to block off the condenser air causing the high side pressure to rise until the eqivillant of 110*F condensing temperature. You can also install a low ambient kit which will cycle the compressor off when the temperatures fall
No power to outside unit. Check to see if contactor on outside unit is pulled in. Most AC units inside have float switch. When the drain stops up it shuts off outside unit. Located in overflow or underneath unit. No Problem Rusty
It could be the CONTACTOR. It could be dirty and when the system calls to run, the contactor won't make contact and complete the circuit. Worse case scenario, compressor is siezed up. If you hear a clicking noise at the condensing unit where the compressor is located, that could be the overload protector clicking and breaking the circuit if the compressor is seized up. Good luck. I hope it is a contactor or a capacitor.
as i am a mechanic in sydney australia, i can honestly say that the chance of you getting help via carrier is very very slim... the reason it is doing that is that it has a legitimate problem unfortunately i have a carrier 42g250h which is flashing 4 times aswell... i have been waiting now 10 working days for carrier to call me to tell me what the problem is... if you can afford to do it, throw the damn thing out and buy a new one, i hate to say it but even an LG will work better than these heaps of ****
