Question about LG Heating & Cooling

Open Question

LG mini split LMU187HV 1 ton and 1/2 ton standard wall units. Error CH24 on cooling only. Bigger unit only causes the error but smaller one just runs and doesn't cool much. Both high pressure lines frost up.

Has anyone added some freon? The unit has way too much freon inside it. You need someone to reclaim the freon and weigh in the right amount of freon. If you run the unit the way it is will cause some very serious damage. Let me know ken

SOURCE: unit leak at high pressure

Sorry about your problems.
The StopLeak is expensive and does not work on leaks larger than 8 ounces per year.
Neither of these "technicians" confirmed the location of the leak and repaired it.
When the vacuum was done on the system a leak would have been obvious after the first tech replaced a valve.
If they did not see a rise in pressure,they are incompetent.
I apologize for not having an answer for you,but,without being there and checking your system,I do not know what your specific problem is.

I searched the website but could not locate the literature for that particular unit. I recommend you contact the manufacturer's technical support department. They should be able to email you the manual and direct you how to obtain replacement remote controllers.

Technical Support
For technical support on a DFS, PTAC or TTW Product call 888.865.3026, then press 2.

I hope you find this helpful with your endeavor. Good Luck! :-)
