what's the temperature in the room the tank is in ? (sounds silly i know)
how big is the tank ? (larger tanks, longer to change temperatures)
i'm sure the tank is getting some light, ... what kind, how much ? (i don't see it having a large effect on heating the tank, but better than ignoring the possibility
how many watts of power supplies everything for your tank ?
-anything else ?
i did have a heater that died, ... no matter what it was set to it was 'on', at 80-something i pulled it out and playing with it, no matter what it stayed on, ... so it found a new home in the garbage.
as you said, your heater doesn't stay on, ... (or stays off as far as you can tell - a dead indicator LED would suck), if you're seeing the temp. drop after it was unplugged, ... i won't say the heater is primary, but i wouldn't rule it out.
try putting it in a bucket of cold water, if it does 'turn on' then it's temp gauge may be defective
ack, i've been doing tech support for too long :(
