Question about LG LB1200ER Air Conditioner

Ac cools but fan keeps cycling

I just got the capacitor replaced on my ac and now the fan cycles through its 3 modes. F1 to F2 to F3 then back to the desired temp. The compressor is on but I'm worried that some other part will burn out. Is there some kind of internal reset switch? I turned it off at the power button, the reset on the plug and at the breaker and nothing works. Is it just a short in the control panel? Thanks

bacause of the following reason
.Timing defrost by turning off:
When defrost sensor temperature defrost temperature (Parameter F2) and at the same time the defrost
interval time reaches the set value F3 then can enter to defrost, the fan will turn on, the compressor and
heater will turn off.
After worked a defrost interval time (Parameter F3) time, it will enter the stop mode automatically and

Display F3 on carrier Ac what problem


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...

Why won't my air conditioner change fan speeds


Having same problem...ac unit seems not to be changing fan speed and cooling level has been reduced ????
I have no solution. but we have just run into the 7 day of 95+ degrees with high humidity. do not believe the units have frozen up, just seems that the fan is in low speed mode and trying to raise it to F2 or F3 doesn't seem to help.??? Most of the time we have to increase temperature because its too cold ?? now it doesnt seem to be cooling the same ??? I await anyones solution.

The AC unit turns on and I can cycle through the options in order to adjust the fan speed however the fan does not start in any of the three settings. The ac unit produces cold air, however the fan does...


You say the unit produces cold air ??? where are you getting the cold air from???
If your fan does not run in any speed F1, F2 F3. and a funny smell sounds like the motor is bad
Mine works in F2, F3 but not in F1

Friedrich xq08m10 - f2 and f3 fan speeds reversed


Unplu cord and remove front panel. Then remove electrical box, you should be able to find the blower motor leads.
Black is usually- hi speed motor
Blue or Yellow is- Medium Speed
Red is- low speed
Just exchange the wires to match the dial
