capacitor

how do I check my capacitor on my washing machine induction motor

[Ray the DJ]

Remove the capacitor.
Connect it across a battery for a few seconds.
Now the exciting bit happens!
Short the two capacitor terminals and you should see a spark from the discharge.
If it doesn't spark then it is not holding it's charge.  You should bin it and buy a new one.
If it does spark, save it and buy a new motor.

thanks ray/dj solved my problem but also had motor PCBdown replaced now every thing up and working

Capacitors can be checked in 2 ways:

-ESR meter (specialist tool)

-multimeter (cheap):

first discharge cap by shorting across it's legs.

Set multimeter to a hi resistance range, connect the cap poles in reverse polarity  to the multi meter. You should start with a low resistance, which ought to change quickly to a high one as the cap charges. If it doesn't, it's bad.

Or, instead of testing, to save time and hassle just replace it -they arent expensive.-
