Good Evening,

I have a saltwater pool with a Hayward saltwater chlorinator. Pool is opened up and the saltwater chlorinator is showing 0 for the salt level but what is odd is that the light that turns green to show the power is on has been turned off. I haven’t cleaned the cell in awhile. I understand this could be it. I also am worried it’s the control board. No idea where to begin. Anyone ever had this happen?
 
Sounds like the cell isn't receiving power. Are you using an AquaRite standalone system? (As opposed to having an OmniLogic automation system)

Yes. I do know that there is currently no automation. I reached out to my pool company and they said I could upgrade the pump from single to variable speed and get a new saltwater chlorinator system with full automation for $5300. Really wasn’t looking to spend that at the moment if I could avoid it.

So nice that your pool company has only your best interest in mind. Spend $5300 to replace a $3 part. I would suggest ditching those guys and finding somebody else who are not trying to rip you off.

It does look a little cracked and discolored though.
Please read through the link that AJW posted above to determine if it needs replacement & how to do so for quite cheap & easy. Its a common thing to go bad multiple times over the generally long life of an aquarite unit.

It was cracked. If I buy the thermistor in the link provided will it work on this unit?
 

Basic AquaRite Diagnostics.​

This is the basic information we need to know in diagnosing a problem:

  • Report all diagnostic readings when you..
    • Move the switch from auto to off and check all of the readings.
    • Move the switch back to auto and recheck the readings.
    • Move the switch to off for a minute and then back to auto and recheck the readings.
  • What are the first seven characters of the cell and box serial numbers?
  • What is the actual salinity and how are you measuring it?

Cell Diagnostics.​

Pressing the diagnostic button sequentially will display:

  • Default salt display
  • Pool temp
  • Cell Voltage - When not generating, the voltage is about 30 to 32 volts dc. When generating, the voltage drops about 1 volt per amp of current.
  • Cell current
  • Desired output (% of the knob)
  • Instant salinity
  • Product name
  • Software revision (r.XX)
  • Cell type

We cannot judge your abilities.

You need to snip off the old termistor. You have long legs on the thermistor and can snip it at the top and leave the legs connected to the board.

Then you can solder the new thermistor legs to the wires connected to the board.

There are many YouTube videos on soldering and you can practice on some scrap pieces of wire.

Yes. Just be sure you're capable of soldering the old one off and new one back on without overheating the traces on the circuit board.

:goodpost: Yup, this is a big one. I burned out some board tracings (and nearby components) when I was learning to solder because I was not working with a clean tip andspent too much time dumping heat into the circuit board's pad.

I found buying some inexpensive DIY soldering kits off Amazon really helped. Quickly moved from through-hole soldering to surface mount. Well worth the minimal expense and time to level up your skills before potentially putting your board at risk (which would be a more expensive cost to replace).

That is why I described above soldering the new thermistor to the old legs and not the board.
