My new cobalt heater is set at 78 degree when plugged in (green LED) But when I touch/push the button on top, the LED does not move, it stays at 78, water temp 68 (yellow LED blinking) stays like this for hours. what went wrong?

Either not pressing hard enough to move the green LED, or it could be defective.

Hi Willa,depress the knob counterclockwise to IGN and when the heater lights then turn to one of the 3 settings; IGN if you want heater to be able to easily light the next time, LO if you want medium heat, and HI if you want the full capacity of the heater. Works well for us.Hope that helps, Fondly, Richard

It heats the water to the desired temp. So it turns on "red light" when the degrees of the water is lower than the desired temp. If you set to 85F it will stay on until the temp of the water is 85F. However, I noticed it heats great but doesn't decide "temps" great. So I bought a Finnex Max-300 Digital Aquarium Heater Controller and the in-line heater will only turn on when my "much improved" controller tells it too. I have my controller set to 82F and my in-line set to 85F. So if the water is 81, my controller turns on power to the in-line, the water starts heating, and once the controller gets to 82F, it shuts off power to the in-line. I did this for "fault protection". I heard this in-line malfunctioned a couple of times, got stuck to 90F and never turned off. Fried all the fish in the water... Go get the Finnex Max-300 Digital Aquarium Heater Controller, you'll thank me later!

On the both remote control or on the side of the heater unit there are triangle shaped markers under "temp setting" that point upward or downward, you press on them and each time you do you will hear a beep and see the lit up digital number change. For example if it is at 68 and you press the upward pointing triangle once it would show 69 degrees. I believe it will only go upward to a maximum of 80. Hope this helps you figure it out : )

Must be something wrong with your heater. When I set the heater temperature to 71 degrees the heater will stay on until reaching 73 degrees (don't know why). Once it drops to 70 degrees then the heater should come back on. The heater will tell you whatever the temp is in the room. When it's extremely cold the heater can't heat some rooms. Hope this helps.

If memory serves you adjust the temperature with the bottom handle. You have to push that button inward and turn the handle counter clockwise...if this doesn't work make sure the water hoses behind the unit are connected to the correct pipes. Hope this helps.

Hello Jackie, to be honest it's a small margin for error with this heater. My heater still works and some times the temperature settings work. And when it does, it's because I have somehow lucked -up in getting it to work. Sorry, I'm sure this was of no great help; good luck

We just bought a new MK32E for our daughter's barn. The heater on mine was attached directly to the underside of the water pan while this newest one has the heater sitting away from the water pan, suspended from a small arm. Ours froze up last year at -25 degrees but increasing the thermostat setting seemed to solve the issue. With the heater away from the pan and at -40 a 500 watt heater might be taxed beyond its capacity. I used to put a 100 watt light bulb inside our unit in the winter just to be sure it did not freeze during those few sub zero days.

The LED should turn off when the temperature is reached. Turn the temp all the way down, then turn it all the way up. Once you pass the temp of the water it will turn the red LED on. Do you have a accurate thermometer to check your water? If it is at 85 then the unit is working. If not then you might have to return it since the calibration is off. Mine is set to 80 and it work very well.

I found I had to set the temperature a few degrees higher for it to come on. I believe this is because the sensor/antenna is close to the wall. I am trying to remember how the programming works. I just have mine set at 72 round the clock. I will check when back home. But I love this unit! Nice steady heat and electric bill did not go up.

If the heater has been off for a mounth or two you have to keep the piolot ---temp control knob pressed down , sometimes for a minuit, but hit the sparker button every 15 seconds till the pilot catches, keep holding the knob down for 40 seconds, the pilot should keep burning, then just set your temp. Hope that's all it is Jon.

I would unplug it and replug it in, and go through each step again. When I first started using it, I would forget and set the temperature first instead of last. Look for the blinking dot next to the temperature.

I'll check with a thermometer later but it should be warm enough to notice. Also, it takes a few minutes to get rolling. I would suggest flipping the heat switch on and off about half a dozen times; the contacts may be oxidized if it was shipped through a moist location. Simply opening and closing the switch may be enough. I had the same trouble recently with some surge suppressors.

I use Energizer, my light has no appreciable change in temperature. Are you able to say if it is the 'light' (LED) or the battery that's gettinig hot? I suspect it is the battery. If so, then the battery getting hot would be the result of excessive current draw (think of if you've ever shorted/briged a battery, both the battery & conductor get very hot), and the battery itself becomes weak/dead. All that to say this:If the battery is getting hot, then the LED is too much load for it - consider using a battery with a higher mAh (milli-ampre-hour) rating. If the 'Light' (LED, or any other part of the torchlight assembly) is getting hot then the unit (flashlight or its components) is defective.

The unit is remains relatively cool to moderately warm but not Hot! I have had the display on for 12 hours straight and no over heating issues occurred. LEDS are cool to the touch.

DittoI tried to put a heater in and found the same problem - if anyone knows how I'd appreciate info too. Thank you!

There is not much to the unit, so if the light is on and the dial is to high, you may just have got a faulty one. I would try another outlet, in case there is a minimal power issue on that (to be sure), otherwise if its not heating up on your first try, it maybe defective.
