No.. it won't.. this is mains voltage..

230V AC voltage is the rms value(average if u like)..

AC voltage is not a constant like a battery DC voltage, it is a sinosoidal waveform at 50 times/sec (Hz).. with peak to peak values of about 340Volts..

Replacing a 250V rated capacitor to a 230V ac mains supply will soon heat up and damaged ..  you must use a 450V rated capacitor and a proper metalised type if for the start/stop compressor motor.. (heat dissipation)

The fan motor u can use the correct rated polypropylene cap 450V or higher (never less)

Oh... thanks for such pro explanation!cool. Does it mean, capacitor value should be (better to have) the double value of main current (220-250)? So 450v acceptable in this case?

What symptoms on the aircond would be seen if there is a capacitor problem?
Cannot start? Aircond not cold?

Not cold then yellow LED (timer) flashing! Check on Compressor,no more activity. But when you restart it,it came back. But soon it'll then totally not functioning!

Becareful to Isolate all the power supply before working on this.
Some capacitor still store charges after switching off.
Just let it in the OFF position for about 5 minutes before touching it.

Oh... Heard about this! They called it discharge , right? Some mentioned to use light bulb or screw driver (with rubber handle) to discharge the capacitor! So, as you mentioned, let it sit for 5 mins (Power Off) will do?
