Testing a capacitor

[Bunker]

Can anyone advise me how to do this? Strangely Ive not replaced one before (plenty of motors). I know the microfarads rating is on the side of it but, and please excuse the question....wth is a farad? I know you test it on resistance but whats the procedure please?
Fank ooo.

My multimeter has a setting to test capacitors.

is not resistance if I remember. Its charge. More few 10k's can give big spark

whats the capacitor on?

Pump??

A Farad is the unit of measurement of capacitance.

Burner motor. The motors buzz pretty well when the capacitor goes.

You need to de energise it by putting a long screwdriver across it to a earth point. if you don't de energise it you could get a serious shock.

And then what Rob...?

First discharge it as Rob has stated

Then put your multimeter across the pins setting it in the high ohm range 10k-1m

Should start at zero and then move toward infinity, if it doesn't the capacitor is knackered.
