How to fix ac daikin 1.5 PK inverter which has U2 error on ac type (RKD35GVM4). The U2 error code is the detection of an unstable DC voltage failure on the ac outdoor pcb module circuit. Usually from the official dealer will replace 1 unit of the ac outdoor pcb module. But I will try to fix it, after checking the outdoor pcb module there are 4 230V 900uf type capacitor components that have been damaged. But these components are rarely sold on the market rather difficult to find it. Then I use capacitors on the market, I get a 250V 470uf type capacitor and then I modify it, I wind up the two capacitors to get a value close to above 900uf which is 470uf x 2 = 940uf. And 250V used has exceeded the limit of 230V which was previously used so it is safer. After replacing 4 damaged capacitor components, the air conditioner is working normally and cold again, the U2 error code has also been lost.

Hopefully useful and I say thank you.
