Thermistor ?

[Philo]

My neighbor has a Hayward Swim Pure T-15.
When he replaced the cell, the genaeric recorded 4900ppm Salt while the Taylor K-1766 showed 3600ppm. The lights indicated everthing was working and it was really generating Chlorine. He could cut the production down by 30% from the previous OME cell.

Today I noticed that none of the lights were on but the display was working fine
4900
80
2.3
0.0
100p
-0
AL-0
r1.40
(both directions)

If I turned it off and back on, the flow light would come on red for 15 seconds and then go out and NO power or generating light would come on.

Does this seem like a thermistor issue?

Thanks

Sounds like the Thermistor.

Open the box and look at the board.

Probably a bad thermistor. The high amps probably contributed to the failure of the thermistor.

If the amps are 8.0 or higher after you replace the thermistor, you're going to have to reduce the salinity.

Thanks!

The thermistor has deteriorated.

Is there a left and right or forward and backward when soldering it in?

There is no polarity on a thermistor.

P.S.
Is there a higher or better quality replacement?

I would use this one:

This one is more heavy duty, but it's harder to solder.

AS32 2R025 Ametherm | Circuit Protection | DigiKey

Order today, ships today. AS32 2R025 – Inrush Current Limiter 2 Ohms ±25% 25 A 1.181" (30.00mm) from Ametherm. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

The first one has easy bend legs. The second one has stiff legs and they don't fit the older holes.

Perfect
