Broken Heater, or too early in the morning...
I was cleaning parts of the tank yesterday and took my heater out do that business. (unplugged)
Well, I messed with the dials a tad bit, and now the heater won't turn off.
I woke up to my tank at 84 degrees and the heater was still on..
Its a Jager heater by the way (the one w/ the blue dial and red arrow)
So I tried to calibrate it again:
put my thermometer right next to the heater, set the red dial for what the thermometer said,
turned the blue dial to where I want the temp at.
which is obviously cooler.
plugged heater back in. and it's still on. UGH!
I didn't have time to mess with it more this morning, so I left it unplugged, put a glass cover on top and set my house to 72deg. i'm confident the water will be held at a good temp for the day. its 45gallons of water.
Any ideas? Did the heater just give up? or I'm dumb w/o my coffee? lol

I would venture to say that the contacts in the relay have finally built up enough carbon or corrosion that they have become fused together. Time for a replacement I suspect, however I do not own any Jager heaters. I keep a spare on hand just incase something like this happens to one of mine. I hope your fish are all ok!

Turn you turn the dial to the lowest temp to see if it turned off? I don't pay attention to (nor trust) the numbers on mine. I just checked mine and it's set to 70F to keep the tank at 78F. The way to calibrate a heater is to turn it all the way down, then slowly turn it up until the on-light turns on. Turn it slightly more, wait til the temp stabilizes, and continue doing that until the tank temp reaches the desired temp.

Just got to thinking about that method over lunch.
the tank water as is (before I left was at 78deg) and it should cool only a few degrees during the day...so I should set the blue ring and red arrow to the same exact thing (for whatever the thermometer reads)
the light should NOT turn on (meaning it is heating) correct???
If it does, means there is an issue w/ the heater?
Another test-set the red dial to thermometer temp-then move blue dial to a cooler temp: which would mean: Don't turn on?
How does that sound?

i believe most heaters turn on for the first few mins when they are plugged in. also if i remember correctly the red arrow is the calibrator and the blue ring is the temp. when you set temp you observe the temp and then set the red arrow to the temp your thermometer reads, then adjust from there.KING OF THE GOLD BARBS RAWR!!!!
I wonder if i plant one of my tiger barbs would the demon seed grow to a full tree?
gotta love them bunnies!

Since aquarium heaters aren't very accurate, you really can't go by numbers on the dial. I'm not familiar with that heater so I just looked up the instructions on how to use it. The best way to check if it's absolutely busted or not is to set the red arrow to the highest temperature (indicating that the tank water is really hot), then set the desired temperature to the lowest temperature with the blue ring. If the heater stays on even though the heater thinks the water is already way hotter than you want it then it's time to replace it. If it's not on, then you just need to calibrate it so that it reaches the desired temperature. Hope that makes sense.

That makes great sense.
However, with this version of the heater-the red indicator arrow can only move within 4 degrees of your "set temperature on the blue dial"
@Genocidex: you are correct, and I tried that-i set the red indicator to 84 (what it read) and the blue ring to 80 for my desired temp...to drop the temp, but the heater stayed on.
I'll try again tonight. Maybe I jumped the gun b/c I didn't wait very long at all after plugging it in and seeing the light indicate it was on. i'll give it a longer time frame tonight

If that's the case then just set the desired temperature to the lowest setting and the current temperature to 4 degrees higher. It should have the same outcome. In other words, set the desired temp to 70 (or whatever the lowest setting is) and the current temp to 74, and if the heater stays on then I don't believe there's anything you can do.

There's one thing to do: smash it. lol
Got home, my trick of keeping the warmth in worked! tank was at 78 deg, not bad after like 10hrs!
Set the red dial at 78, and then moved the blue dial to 74. Plugged it in, and the light has been on for the past 30minutes.
These are supposed to be the best heaters on the market! and its only been like 9months with this one.
I guess, i'll take advantage of this "opportunity" and buy 2 new ones vs one big one. I wasn't a fan of the diagonal/horizontal mounting anyways.
so for a 45gallon tank, would 2 125watt heaters be good?
They are 12inches long, so it leaves me 4 inches of wiggle room on substrate/water level-so i can mount them vertically (the "correct way")
