Hi, if you have a leak in the evaporator coil which this happens a lot and they came out and didn't try to make any attempts in finding and repairing the leak or they found it in the coil and didn't order a new one, this is against the law by E.P.A standards. They must make every attempt in making the repairs if it means replacing the coil, no if, ands, or buts!! Keep your receipts on them charging the system. Now that its out of warranty, I would call them and bring this up about not changing out the coil when the leak was found. I am sure they used dye to locate it.I have found more leaks in the evaporator coils then I care to count, and had to replace the coil. This is something you can't do on your own I must say, as it takes special equipment to do this job. I would call the Enviormental protection agency and tell Carrier you will do this, and report them. I bet they will stand behind it then. You have to get tough with them. I am a air conditioning contractor and know the law. The E. P. A. will get them on the ball trust me. This is bull+)_(*&%!* !! Don't let Carrier walk on you, this coil should have been put in the schedule to be changed out right away, not to continue to charge it to get you through. This is a 3 ton split system. Stay on them, this will be covered if you make the call and stay on them. The E. P. A. are very strict on this as this is why they have stopped us from venting freon into the air, they have very strict guide lines we must follow and Carrier did not follow them on your unit. Please keep me posted, and the best to you.

If the compressor and fan work in the outside unit, and the fan inside (air handler) works, probably the system is low in refrigerant which means there's a leak that has to be fixed and then recharge the unit.

The fins are dirty. They need to be washed every year or two with an acid based cleaner. They MUST be rinsed completely.

Problems with the fan are one of several things to consider.
1. Is their power to the fan motor.
2. Does the capacitor for the fan hold a charge and/or discharge (There are metering devices that can identify the condition).
3. Are the fuses blown (If Applicable)
4. Is the breaker to the condenser tripped.
5. Are the windings on the motor closed or open.
6. Are the winding (when using an Ohm Meter, Check the resistance from ground to one of the lead wires, making sure power is disconnected and all leads are disconnected from the terminal points. There will be high resistance if there is not a short from the windings to the frame ground.

These are simple checks I make to determine the motors condition. Sometimes a wire does come loose or cut or even burned. I trace the wire from point A to B and also making sure the wire terminal connections are tight.

I think that you need to turn off power to the unit and reverse the 240v wires that are on the transformer,I think that the polarity it backwards,I had a similar problom with 2 york units,good luck!

the humidity problem is from the condesation drain. It is more than likely to be clogged up keeping water in the condensation pan causing the humidity problem. This can be cured by a wet vac put onto the outside drain for the inside condensation pan and turned on. this removes the algae that builds up in the a/c condensation pans. Also, an a/c unit is designed to last 25 to 30 years depending on the location of the outside unit. Inside unit being an apartment, has other issues, it just may need to have some preventive maintenance done such as coil cleaned filter changed, motor oiled, etc....

Is there a built-in humidifier? That would explain water in the reservoir. Is there a fill cap for the water reservoir?

Well without a model number, I can tell you this. On some models, F3 indicates fan speed 3, which is high speed.If you push the mode button, these units will switch between f1, f2, f3 and smart fan. No problem.
On others, F3 indicates a fan speed error, either something is keeping the fan from turning, or there is a bad or loose connection somewhere.
On still other models, F3 indicates a freon leak or problem in the refrigerant circuit.
If carrier made their own units, they would probably act the same, but they don't. Model number is important, since the unit could be a daikin, LG or Samsung under the skin...

FF code means blown or missing damper fuse. Replace damper fuse (inside equipment cover plate) and try again. If damper fuse blows again, find and fix the problem causing the fuse to blow.

-When a blinking light problem occurs, your air conditioning system often shuts off too, meaning warm air is blown. You can switch off the circuit breaker of your AC unit, wait for a few seconds, and then switch it on again. For some, the unit will start working normally again.
