The starting capacitor of this unit blasted. I need to replace it, but the rating of said capacitor is no longer readable. Can you please tell me the rating of said capacitor and where to buy it here in Singapore?

Ok you need Fisher and Paykel Part number 427616 it's a 7uF PRL M8 Stud. But any 7 uF 240volt AC Capacitor should work AS LONG AS YOU CAN MOUNT IT SAFELY where it won't hit anything or fall off it's mount. cheers

A capacitor only costs a few bucks. The condenser motor may tell you what MFD of capacitor to use. What you could do is 1. kill the power to the condenser 2. open up the electrical panel on the side 3. trace the motor wires to locate the capacitor. As you're tracing the wire, you may run across a low pressure sensor on the refrigerant line also. This would be a good start to diagnose where the problem is. If you're really going to be doing this, you should invest in a good multimeter.
capacitors are not rated by amps, the are rated in microfareds, but that really isn't the issue, how do you know it is going out. The model number of the outdoor unit will be enough to determine the correct size capacitor if that is what is wrong. Mr. G
Hi WFO9,
It sounds as though the fan capacitor is under specs. It is probably losing its capacitance ability, they are usually rated plus or minus 5% of the value printed on the case. If however the capacitor is no longer within the rated specs. the fan motor will draw too much current and will then blow the fuse. either that or after the normal start delay built into the Ac, which is 3-4 minutes, the compressor tries to start and again draws to much current and blows the fuse. have all the capacitors checked and replaced if they dont meet the specs printed on the capacitor case.

it's not the cap's fault that i see as the real problem,the cap is used to start the compressor and is rated for so many starts per hour and if you go over this rating it will stress the cap and after some time it will fail and this problem is known as short cycling and is normally caused by your thermostat.Or the unit is starting up under large gas pressure loads due to air in the system and or moisture and can only be fixed by a new gas charge
If it is the compressor making that sound,The compressor is bad.
A fan motor can as make this type of noise as well when going bad.
If it is the fan motor stopping,this will also shut the compressor down,due to the thermal overload protection.
