LG dual inverter AC CH 26 error
I am using this AC for more then two months it was working fine before two weeks then it started giving error CH 26 and no cooling happens . During daytime when sunlight falls on outdoor unit the outer fan and compressor start running after 2-3 failed attempts ( when fail then outer fan starts and turn off after 10-15 seconds , same happens after every three minutes for 5 times then error display on indoor ) . When starts cooling it may work trouble free untill turned off in evening,night or electricity load shedding but then it don't start cooling as there isn't sunlight anymore on outdoor unit . I called LG guys they checked and blamed voltage issue which is around 205 mostly ,anyway I called electrician and put AC line to maximum voltage phase now it is 230v mostly but it didn't effect anyway . I called other guy he tried to give ground to AC and charged gas to 220 but it didn't fix either . Now I called LG again and waiting for their Rawalpindi team to come and check other sensors ,PCB etc . Please guide about this issue , possibilities and if somebody know any qualified technician in Islamabad Rawalpindi who has experience of fixing such errors.
