speedqueen SC27 capacitor problem

[super80]

today, I found a fuse 250V-2A blow-out in my sc27 machine, and there's no display on coin-drop( normally it display the price), after I replace the fuse with a new one, the display comes back on, then I drop coins to check if the machine works ok or not, after I drop coins ($2.50) to start it, I heard and saw I a "spark" from the capacitors area and fuse blow-out again, so I check those capacitors with a cap-tester, I found that the big one is fine, and there're two small cap. read "1" on the display of the tester, I think those two were dead. My question is anyboby knows what cause those capacitor to death?? if i change those dead cap. to new, any other things I need to check before start the machine, because I'm afraid if there still have something wrong that can damage the motor!! and how can I know that the switch (looks like a capacitor with 4 wires connected to it)is good?? please advise, thanks much~~

First off you need to tell us where these caps that you are talking about are located. Which fuse has blown? (If you have more than one) What it sounds like is that you have a single phase machine. The 4 wire cap looking thing you are talking about is actually a electronic switch (sinpac). If you are blowing a 2 amp fuse I doubt you have a motor capacitor problem. Rather you have a problem somewhere is you control circuitry. Most likely in the drain valve or door lock assy or contactors. Since we cannot see what you see we are only able to make a guess as to what may be wrong. You will need to be more specific in discribing what is going on to get more acurate help.

those five small cap. were connect to the said electronic switch (sinpac) in series, they seem motor related and the blown fuse is just located behind those cap. , there are two fuse sit together and covered with two separate plastic cover, I think this fuse is coin- dropper related (not sure) because after it blown-up the display on the coin dropper was out!!
any further advise??

A short in the Caps shouldn't blow any of those fuses. Disconnect all of the water valve wires making careful note where they all go as well as the drain valve wires. Install new fuse(s) or if you don't like to waste fuses use a piece of solder wraped around the fuse holder terminals. Reapply power and start washer. If fuse or solder doesn't blow then reattach one coil at a time untill it does blow and then you have found your problem. I recomend the solder method as it doesn't cost you anything. If it blows with all the valves and drain valve disconnected then problem is elsewhere. Let us know and we (I) will advise you further. I still don't rule out the contactors or door lock but this is a easier check.

Enjoy hunting!!!

thanks for advise, but I don't really understand what is a "solder wraped " ?? can you show me how to make it or where to buy??
I have one more question, what problem will occur if there's a short in caps, will this cause damage to the motor?? (because I found two small caps read "1" when I use a cap meter to test them)
please reply, thanks much

If a cap is shorted in will most likely blow the breaker when it goes into wash or spin depending what the Cap is used for.

The solder is electronics solder. You know Radio Shack. Soldering Iron. Wrap, twist or tie it around the fuse holder contact just like you were using it as a fuse.

How about those caps that connected in series to the electronic switch (sinpac), if two of them are shorted, will it cause damage to the motor??
and for the soldering iron, will it blow- out if there's something wrong if I start the machine??
thanks much!!

With a piece of solder jump the two connections across the fuse holder. If there is a problem in the washer the solder will melt just like a fuse but at a fraction of the cost.

Why do you keep asking about the caps and motor? Fix one issue at a time.

If you are worried about motor damage due to a cap being bad then disconnect the hot line to both wash and spin contactors until you fix the other problem.

Now the next time you post you have better have some answers or results to share with us.;)

thanks for you advise, the reason Why do I keep asking about the caps and motor, because that is the reason why I start the thread, please refer to my first post, my question is always around those caps because after I change the fuse and start the machine, I saw sparks came from the caps area, so I worry about the caps and the motor issues, and as you know the motor is the most expensive part in the machine. forgive me with my question make you feeling uncomfortable, sorry!!!
and I will try your advise first, hopefully will have good news share with you, thanks much!!

Fuse still blow up after disconnect all water valve and drain valve, any advise??
thanks
