Top 20 LG LS-L1210CL Mini Split Air Conditioner Questions & Answers

You can check LG's website on Air Conditioners that they manufacture at: you may be able to find a number where you can call them for further support. But I would check that website first. Do you know the Model/Serial Number of your unit? This is usually located on a metal piece attached to your unit. Having the correct Model/Serial Number of your product will help narrow your search for manuals to your question.

find an air conditioner service shop in your area as there are non caustic products available to use to clean the fins on the evaporator and condenser
places that sell compressors , driers, evaporators condensers to the air con trade will be the best place to go to
I use a product called viper E+ enzyme power which you spray into the fins of the units and it actively cleans for hours
it is a non rinsing cleaner made by refrigeration technologies part no rt350g
not cheap but very effective

You need to post/research the model # and brand of compressor. The fan motor will state the UF/capacitor rating. There's absolutely no answer to that ? without more info. Sorry. And sometimes that info is only available from the manufacturer. Most refrigeration parts houses can look it up.

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 Air Conditioning Coral Springs

( Power factor correction ) Circuit protection on controls. The LG a/c is manufactured using the PFC and sign wave technology, By the PFC control, Raising the operating voltage from the existing DC 280 v to DC 380 v can be done. Thereby it makes operation smooth in high-frequency area. The sine wave control enables soft operation in low frequency area, Thereby expanding the product's operating range. This also markedly improves the product's energy efficiency. hope this helps
