Been a pool owner since 2019. The pool is fairly old, and I think the previous homeowners knew everything was about to die (not just the pool) and decided to sell.

At opening 2020, IC40 worked fine at first, but then died (no lights). After some research, I determined it was probably beyond it's lifespan (4 to 5 years). I found a great deal, so I bought a new one and installed. Back in business.

Summer 2021, rock-n-rolling, no problems!

Now, heading into summer 2022: IC40 has been giving me no problems. Flow is great, salt conversion to chlorine is great. Then this afternoon, I flipped on the power because some folks were coming over. No lights on the IC40. I jiggled it, lights flickered, went back out, and have remained out.

After some research, I see that if the green light is lit inside the power center, that means the fuse is good. The green light is lit. I could check the fuse, it's just really hard to get to, and since the light inside the PC is good, I'm assuming the fuse is good.

I also unscrewed the couplings and took a look inside, and there is no build up on the converter blades/fins.

Some folks online are saying the step-down regulator in the PC might be bad, but I don't have a voltage meter and have zero experience with anything electric.

I bought the replacement May 16, 2020. Two-year warranty. I'm now beyond the warranty. Yeah.

Thoughts? Is the IC40 dead? I bought for < $700 and now they're listing for $1400+, so I'm hoping it's not the IC40 itself. I'm going to call service on Monday (6/6), but just thought I would ask here first to see if there is anything else I could try.
 
Welcome to TFP.

Do you have a multimeter to check voltages in the Power Center?
 
Thanks for the response! I do not own a multimeter. When ever someone says "multimeter" I begin to feel out of my depth as I have zero experience in that area. I did see several videos on YouTube about testing the voltage step-down regulator, etc., but everyone had a different power center than mine (PC100), and I wouldn't even know where to begin. But I'm willing to keep walking this path if I can get some detailed assistance. I've attached a picture of the inside cover of the PC. I can get a picture of the jumble of wires inside later this afternoon if that would help.

UPDATE: I got a multimeter. Still not certain about what I'm doing here. I was unable to get the probes into the box itself. It's very tight, and very dark, and my vision is not what it used to be. So what I did instead was tried to determine where the red and black wires were terminated in the 4-prong plug. I then unplugged the IC40 and stuck the red probe into the red wire hole (I was certain which one was red), but then moved the black probe around the other three holes. I had the meter set to test DC voltage (although after some other reading here, I wonder if I should have been testing AC voltage).

In the hole that I think is the green wire, I was seeing high 20s. In the hole that I think was the black wire, it was only showing micro-volts. I wanted to spend more time on it, but it started to storm. Any way. Here are some more pics. I'd really appreciate any guidance I can get.

Welcome to TFP.

Update: after my own highly amateur multi-metering was inconclusive, I remembered I have a neighbor a few doors down who is an electrician. He came and checked things out. There is definitely 120VAC going into the step-down transformer, and ~30VAC coming out of it. But when he tests the four-prong connector for the IC40, he's only seeing 2-3 VDC coming out of it. Does this sound like the circuit board is shot?
 
N,

Sounds like the Surge card is dead.

If he tested between the big Black and Red wires going to the cell, and only got 2 or 3 VDC, then then card is bad.

Sorry that I missed your 9th of June post.. :(

Thanks,

Jim R.
 
Well — it took some doing, but I was able to find a vendor with the surge board in stock who also didn't want an arm and leg for it. I installed it earlier this afternoon, and . . . hallelujah! The IC40 came back to life. Now, to get the salt level straightened out and probably clean the DE filter. Ah, pool ownership!
