Pentair IC40 Chlorinator Power Problem

I noticed that the Power LED is not lit (neither red nor green) on the IC40. I acid washed the IC40 as it was very dirty and completely plugged between the middle grids. I reinstalled the IC40, but the LED was still not lit. I then replaced the fuse in the power center, but still nothing even though the green light inside the power center was lit. I then removed the fuse holder and checked that I do have continuity between the two terminals. I reinstalled the fuse holder, but still nothing.
Is the problem with the IC40 itself or is the problem with the IC40 power center?

Check the output voltage on the power center -- it should be between 24 and 39v DC.

If it's not, you have a power center problem. If it is, you probably have a cell problem.

Thanks.
I measured 25 vdc. I'm going to replace the IC40 cell.

Don't throw your old cell way -- you may need the flow switch or embedded sensor off it, at some point. You can remove the switch and set it aside.

Thanks. I look into how to remove those items.

My bad -- sensor is embedded in the flow switch -- there's only one unit.
