Purchased the unit for my above ground pool a year ago. Everything has worked pretty much trouble free for the remainder of last years season & the beginning of this year till this past week. Upon daily checking on pump, chemistry & swg unit I noticed the automated timer had not turned on the pump & there were no LEDs lit or any display showing on the Aqua Trol unit. First unplugged the unit & the pump from the unit. Checked my breakers and none had been tripped. So I plugged the pump into the power supply separately, it turned on fine. No problems there. Took off T-cell to check it over & clean it out and reinstalled it. No leds or display still. Got my manual, checked the troubleshooting area and removed the cover to check the fuse. It was fine but went ahead and replaced it anyway. Still no display or LED's. Can hear unit click when plugging in and a slight hum in the box as if power is supplying it somewhere. Checked over the viewable side of the boards and there does not appear to be any broken soldering, cracked items, burn marks, or shorted out spots. (Haven't removed anything to see back.) Checked cord going in and it appears to be getting power but nothing seems to be passing through to pump plug in or readouts. Was wondering where to go from here. Thinking possibly a relay on the board itself or possibly the transformer up in the corner may be the problem but not sure. Hoping someone may have any ideas on where to start. Hate to have to buy a whole new unit since it's only a 1 1/2 years old. Since I live in a rural area I highly doubt a technician will come out to do any repairs and if so it will probably cost more than the unit did itself. I have been down that route with both a refrigerator & a spa. So far the pool is staying clear & stable but would like to get this problem solved without having to go and purchase chlorine. Any ideas?
