Cobalt equatics neotherm help

Mr Hughes · Feb 15, 2018

So I just noticed that my neotherm has a solid yellow/orange led lit at 70 degrees with a blinking green 78, where I normally keep it. Any idea what the yellow/orange led is signifying? Usually it’s just solid green at 78. I tried unplugging and plugging back in, but that didn’t work.

I believe that is telling you that the setpoint is 70 degrees and the actual tank temp is at 78 degrees.

Typically atleast on my Neos the flashing yellow light shows the actual temp reading (when lower than set temp) with a solid green as your set temp, 1 solid green is your temp when it matches your set point and flashing green over solid green is usually temps over your set point. I've never seen a solid yellow with a blinking green... @Brew12 might be right as I've never gone 8 degrees over set only 4 so maybe when it goes that much over it changes from solid green to solid yellow. do you have a thermometer to check the temp in your tank?

Thermometer was definitely set at 70 somehow. Definitely was thrown off by that as I hadn’t messed with it. Now to figure out the cause.

I would agree with Brew12

Did you have a power outage or anything that caused a reset? How did the tank maintain temp without a heater, do you have a backup?

There was no power outage. I was working from home all day so I know that for a fact. As for maintaining temp, it must’ve just happened as it was still blinking at 78. By the time I panicked, wrote the post, and went back to it, it had dropped to 76. There currently is no backup (part of the reason I panicked), but that has substantially moved up the list of things to update. Guess I just got lucky this time.

I would contact Cobalt. They VERY rarely have faulty neotherm heaters. After discussing the issue I had with mine they immediately sent me out a new one. Great customer service, they will either help troubleshoot or replace.

Depends when you got one. There was a production date range that had ALOT of heaters failing ,melting, blowing up,smoking etc.

I believe that was solely around the 300 Watt heaters. @Mr Hughes what wattage is your heater? If its a 300, is it a single 300 or one of the newer ones daisy chained together (2x150)

This was an issue with one specific model and was fixed long ago. I'd say as of late saying they rarely fail is a very accurate statement, I own 4 myself and love them all. Not trying to downplay the failures they did have by any means as they were massive catastrophic ones that caused untold amounts of damage.

It’s a 150 that was bought about 1.5 years ago. It is in the main display so I’m wondering if a snail got wedged somehow. That would be concerning.
