Earlier this year, my t 15 died, I replaced it with an aftermarket version and it has worked well. Best part is the clear elbow that allows you to see chlorine gas being produced...which it was yesterday.

I just checked and only found 2.0 FC, not good for my 50+ CYA.

Figured it was just turned down and the relentless sun was burning it off. Opened the cover of the controller and none of the lights are lit. Even when turning to super chlorinate or turning the dial to 100%. No lights and no visible chlorine production. My wife saw it yesterday and I saw it for sure Sunday.

The readings are as follows:
4100
90
0.1
0.00
-0
AL-1
r 1.58
t- 15

I did the "Charter Cable" shut it off and turn it back on and the red no-flow light blinks for the normal 20 or so seconds, then the green generating light blinks for about 10 second and shuts off...still no power light.

I checked the capacitors and the thermistor and they all look good.

What are my next steps?
 
For AquaRite, 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.

Switching the unit off and then back on makes the unit reverse polarity.

Report all readings.

No change...all values are the same in all 3 cases. Still no lights lighting up except Generating for 10 seconds
 
Can you show a picture of everything including the thermistor?

What is the AC voltage from the transformer on the two yellow wires (red arrows)?

What is the DC voltage on the red and black from the rectifiers (blue dots)?

Shut off the breaker.

With the switch in the OFF position, jump the two legs of the thermistor with a jumper and then turn the breaker back on and recheck the readings.

Don't short anything out, just jump the legs of the thermistor.

Leave the Aquarite slider switch in the Off position.

Now that' it's daylight, I can see a crack in the thermistor.

Gotta see if I can find the spare I bought 5 years ago...

Thanks for the help.
