How long before it goes from cold to hot. The compressor could be not running and going out on overload. The condeser fan could have failed. Did you check the outdoor unit. Is it running? Is the fan running on the outdoor unit. It could be low on charge which would cause ice. Are you getting excessive condensation? Let me know and i can help you out more. Grab the large copper line outside that is insulated and tell me if it is cold. It should be cold like a Pepsi out of the fridge!
It is possible that the contactor points have carbon or dust deposits causing an intermittent condition or bad connection. Why not try replacing the contactor?
The first thing i'll say is you will need to get it repaired by a technician and i strongly recommend you not to do it by urself.
Remote control units have diagnostic program in the control, after 3 to 5 minutes of operating if the diagnostic tools detect abnormal operation, then its shutdown the unit to protect from damage. Thermistor sensor is one of the parts that detect the operation of the unit. Out of range or defective thermistor can shut the operation of the unit. -If your indoor and outdoor is clean start the
unit in cool mode and monitor the outdoor pipes. If your suction pipe is icing
or dry then your unit is under charge, but if your suction is cold and sweating
then the system is ok and sure that the thermistor sensor is defective. -Out of range thermistor sensor in both return
air and freeze up sensor can cause the tripping “off “ the unit.
The FL error usually means that there is excess water in the drain pan. Look for the drain plug cap at the bottom of the back of the air conditioner. Remove the cap and tilt the air conditioner so that any water in the drain pan will run out. If the room is extremely humid and the air conditioner is set to Cool, this is normal. To reduce the water level issue, set the fan speed to Low. If the air conditioner is in the Dry (dehumidifying) mode, try setting it to Cool. Alternatively, consider using a hose if your unit allows for a continuous drain.
Unplug the air conditioner for at least 10 seconds to reset the unit if the error persists. If the drain pan is dry or the error recurs before more water fills the drain pan after the reset, then the air conditioner needs service.
Please add a comment with the model number of the unit if you need help finding the drain pan cap. I hope this helps.

The error is that the DC voltage is too high, not the house AC voltage. It should regulate through a transformer. Get LG to send an engineer under warranty. If you have a multimeter, you can test your house voltage.
DC peak error / IPM fault; compressor DC voltage was too high.
You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. Also What is the model of your air conditioner. With out that information i cant help you with your ac repair problem

Possibly a stuck or closed defrost sensor. The sensor gets to freezing which closes the switch. So the unit goes into defrost cycle which switches the flow of the freon on a Heatpump. The hot gas thaws the coil and the sensor. Which opens the switch and switches it back. I'm giving this answer without knowing more about the unit. Defrost light comes on & it doesn't run at all? LG system is a split unit or window unit or what? If you need further help, reach me via phone at https://www.6ya.com/expert/thomas_868a5ee3bf9eea64
Question edited for clarity and translated to English.
A CH 24 error code indicates a pressure switch error. To Resolve: Make sure the air filter in the unit is clean. Remove any items or reposition the unit so that the air flow is not obstructed.

It sounds like you were experiencing an issue with one of the indoor units on your LG dual inverter air conditioner, where it was stuck in defrost mode while the other unit was working properly in heating mode.
It sounds like you've already replaced the control board of the indoor unit that was stuck in defrost mode and it fixed the problem. The control board is responsible for controlling the various functions of the air conditioner and it is a common cause of malfunction in air conditioning systems.
It's great that you've been able to fix the issue, but if the problem comes back or you're experiencing other issues, it's best to contact LG's customer service or a professional technician for further assistance.
It's important to note that troubleshooting and repairing air conditioners can be dangerous, especially if you're not familiar with the device, so it's best to contact a professional technician if you're not comfortable working with it.
These units cool better than they heat, and if the temperature ever drops far into minus 'C digits, they don't work at all.
I have found that turning off all power for a minimum of two hours will reset most errors,. When you switch the breaker back on, you will hear relays clicking as part of the self testing. Wait 15 minutes before operating the unit.
It sounds like your installer doesn't want to deal with you any longer. The engineers get very basic LG Service training, so at stages they are completely lost. I was advised not to buy LG and went with Fujitsu, but they have their own problems as it seems they all do!
Phone LG Support on Monday and ask their advice, don't let them just say call for service. Tell them you want to speak with a technician that does the training sessions and seminars.

Question moved from LG Office Equipment Category.
Sorry for the delay in getting back to your question.
Try disconnecting the power at the breaker for at least 2 hours and preferably overnight. This fully resets the units and it will do a Self Test when you switch it back on. Wait 15 minutes before operating it. 5 Blinks is a loss of communication.

Check the remote control: Look for a button on your remote control labeled "Beep" or "Sound". Press this button to turn the beep sound back on .
Check the settings: If you can't find a "Beep" or "Sound" button on your remote control, check the settings menu on your AC unit. Look for an option to turn the beep sound on or off and make sure it's turned on .
Reset the AC unit: If neither of these steps work, try resetting your AC unit to its factory default settings. To do this, turn off the AC unit and unplug it from the power outlet. Wait for a few minutes and then plug it back in and turn it on .
If none of these steps work, it's best to contact a professional or LG's service center for further assistance.
I hope this helps!
have you cleaned filter a regular basis? dirty filters will cause low air circulation. go to long and the evaporator coil is dirty and plugged and will require cleaning. There is no E9 code listed the E5 code describes what you have. Have you been emptying water collection tank?
