Submersible aquarium heater keeps turning off, even when I don’t unplug it?

I’ve had this problem twice on my 10 gallon tank heater, and now I just had it happen on my 55 gallon heater – any ideas? They are set to the temperatures I want them at, and they are plugged in to working outlets. They were working (I could see the light was on) but this morning I noticed the water was very cool in the 55 gal. tank. Lights out on the heater! And I can’t seem to get it to come back on – I’ve tried unplugging it, and plugging it back in; tried a different outlet, even tried shaking it.
With the 10 gal. tank heater, it would come back on when I shook it, and I haven’t had problems with that one for awhile.
Sounds to me like the plug where this is all plugged in is not working well.To risk not having a fire I would put a socket in that is used around water.Power to home must be turned off first.Get someone to do it that knows what they are doing.Good Luck!
Well, this is an easy answer. From your dexcription, it sounds like the water is too hot for the heater to heat it up because there is no use of heat.,
Change or replace the heater, its not working properly, which is dangerous because its a electrical apparatus.
1st put a desk lamp plug in socket turn on and it lightds,socket not the prob!!!!
2nd plug in thermastat and turn the knob at the end up till it lights. no light thermastats kaput!! it lights thermastats ok
3rd if ok reset temperature and keep an eye on it if it turns off and on then ok if it turns off and stays off its kaput get a new one.depending on the output range of the thermastat i would buy two for the 55 gal tank one each corner which will give you a better all round temperature for you fish.
hope this helps you.
It might be just way the heater works. I have four heaters in my three tanks and every one of them turn off automatically every couple of minutes even before the water reaches the set temperature. They do that so they don’t get too hot. If your heater never turns back on after it shuts itself off, you have a problem. If it just shuts off every couple minutes and turns itself back on after awhile, it’s working fine.
may sound a bit stupid but does your plug have a fuse? sometimes the easiest things may be left unseen, if not change it, had the same prob in my 50 litre but now in my 330 litre the termostat got stuck and the know is reall hard to turn so have to get a new one.
