board went bad I think... need help

[carl292]

Hi everyone, I have a aquarite swim pure and I was told by pinch a pny that the board went bad. Just replaced it a lil over a yr ago. Basically when it turns on the no flow appears after about 30 seconds it goes away, the generating light comes on for 5 seconds and shuts off. No power light or any other lights appear on the right side, but all the display functions work fine/. I am being told it is $319 for the board. It seems very expensive for something that was replaced not too long ago. Advice/ thoughts???

That sounds kind of like the common current limiter problem. See here for more info.

Thank you! Now the next question is it the SL32 or the AS32 current limit switch? The repair guide shows 2 different part numbers and so does the website to purchase. I think they have different ohm ratings.

Ok, parts came in from digikey.com and i am use my old solder iron and for some reason the item i am trying to desolder will not liquify to be pulled out. I can melt solderfrom a new roll, but the stuff in the board will not loosen so i can pull the piece out. Just gets a lil brown and nothing. New solder iron or ???. What u guys thinks ? Thanks

Sounds like the soldering iron is not hot enough. Have you replaced the tip? Even a cheap soldering iron and desoldering braid should do the job you're trying to accomplish.

Try adding a little new solder while the hot iron is sitting on the bead you are trying to remove. It will help transfer more heat from the iron to the board.
