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

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

The remote keeps needing to be reset


I would say the f1,f2,f3,f4, is speeds on the fan motor.If you turn the unit on to cool then I would say you need to keep the fan running all the time.But need to run it med-high or high speed to give good cooling.

F1, F2, and F3 are the strength of the fan blowing the air conditioner. F1 circulates the least amount of air, F3 the most. I generally find that if the air conditioner isn't getting the job done on F1, F2 will do it. I typically only use F3 if I just want to circulate air fast in my place for awhile. As far as what is "better" with closed vent or open, that depends on what you want to do. If you are using air conditioning on a hot day, then vent closed is better because it will cool only air circulating in your place. Vent open will allow fresh air in from outside, and if it's a really hot day, the air conditioner might have a harder time cooling off the fresh air than the circulating air inside your place (as it's continually being cooled repeatedly by your air conditioner).

F1 - F3 are the fan speeds when the air conditioner is in fan only mode.

The vent can be opened or closed based on your preference. When the air conditioner is in a/c or dehumidifier mode having the vent closed will cause the a/c unit to recirculate the room air and cool / dehumidify quicker. When you open the vent the a/c unit takes air from outside and cools / dehumidifies it. It is obviously not as efficient this way but it does bring in fresh air.
