[2002 Tiger River Bengal Flashing Ready Light]

 

The thermostat logic is in the control head on that model... But you don't want top throw one at it unless you're 100% sure it need replacement. Since you have an extra set of thermistors, unplug the *control thermistor only* from the IQ2020, and plug in the spare *without* installing the spare in the heater. OHM out the one that's still in the heater, but not plugged into the control box. This way, you can manipulate the temp of the water simply by placing the thermistor plugged into the IQ2020 control into a glass of water (at whatever temp you need during testing) while OHM-ing out the thermistor that's actually in the heater. This will reveal if the problem is a logic problem, mechanical, or a flow problem. In other words- have a glass of water at 100F, or 102, or 120... or whatever, and dip the thermistor into that water so the spa logic believes the temp of the water is THAT temp, until you get the green light to flash.

You can see what the thermistor in the heater is actually reading when that green light flashes in this fashion, and this will reveal where the problem is, and what to do next.

 

Alright, so I did all of that and it was causing the ready light to flash so I went ahead and got a new control panel and all is well now. I don't quite get it because you would think if it was a faulty control panel then it would heat to say 101 and think it's at 104 or something but not freak out and turn off when the spa hits 100 because that's the hi limit thermistors job. But oh well, it works now so that is good enough for me. Thanks.

Okay, I will give that a try when I can get to it. Thanks.

Oh, umm, thanks for the rude and inaccurate response. I don't know what that was about. I guess I should apologize to you for draining my broken spa and now trying to get it fixed again. Also, I'm glad you read that one part where I wrote, "Even had a spa tech come out and he said straight up, I'll be honest with you, I don't know. I could throw parts at it but I don't really want to because I don't know what's wrong with it. So he was no help." Maybe I should have wrote "pro" instead of spa tech.

Anything else you would like to be a *** about for no reason?

Okay, a year later, a few parts later, still a no go.

Here's the deal again; The spa is hooked up via 115. It will heat to 100 degrees exactly every single time I unplug it and plug it back in then stop and the green light will flash. If I plug it in at 75, heats to 100. If I plug it in at 92, heats to 100. Ran jet clean. The thermistors have been replaced...twice. The circulation pump has been replaced. It has a new filter. The circuit board and heater relay board have been replaced, unrelated, but new anyway. Even had a spa tech come out and he said straight up, I'll be honest with you, I don't know. I could throw parts at it but I don't really want to because I don't know what's wrong with it. So he was no help. Basically the only thing that isn't new on this spa is the control panel and the heater. But from what I have read, if it was the control panel, it would just flash right when I plugged it in, not heat to 100 first, but I don't know. I've replaced everything myself, which is significantly cheaper (like 80% cheaper) than having a tech do it after parts markup and labor. I'm not out all that much all things considered, so I don't mind replacing the heater, $300 on backyard plus or the control panel, but I dont really want to do both just guessing. Does anyone have any idea which one could be the culprit, or whatever other voodoo could be going on with it? I really don't get it at this point.

Okay thanks. I will try the Jet Clean first. If that doesn't work, how do I go about figuring out if it's a worn out circulation pump or a heater issue?

[2002 Tiger River Bengal Flashing Ready Light]

I have a 2002 Tiger River Bengal spa. The spa is having a problem where the ready light flashes and then it stops heating. Unplugging it and plugging it back in will make it heat again, but eventually the ready light will begin flashing again and the heating will stop. I have replaced the 2 thermostat pieces and removed the filter so far so those aren't the issue. Any ideas?
