Tuned 3155

Over the past couple of weeks I have come in to my sump room to find my ATO not seeing the water below the sensor. I have cleaned but still was inconsistent. This morning I found that moving the wire directly above the sensor was making it work (or not). It appears to have a short.

How do I go about repair? Is there any other troubleshooting I should try?

How old is it? The optic sensor can be replaced, if it is newer it is a plug in, older it has to be soldered, this changed in 2015.

I purchased it in August of 2015 but doesn't have a plug. I tried soaking it for about 4 hours yesterday in vinegar (didn't shorter period last week). Since plugging last evening it has been working. I will continue to monitor and update you.

Would it be possible that wiggling the wire would affect it if it only needed a better cleaning?

Thanks for your help!

It could be, the sensor can just be hazed over and nearly blind and moving it just enough might get a better signal.

I hope that is the case and will follow-up and let you know.
