Just got a call from my wife and the heater controler stuck on and spiked my temp to 98.9 lost my frog spawn hoping that is all but will see hoping. My mushrooms will b ok ....
This is why you dont turn your heaters all the way up.
The controller should be set up to turn off if the heat goes above a certain temp, but the heaters should be kept below that temp. So this is a safety in case heaters fail.
I never understood why people put their controller for like 80 and put their heaters at 90.
that said, sorry for your loss.
EDIT: your title is misleading. When you said: "heater controller" I thought you meant a controller used for the heaters. You might want to change it to: "bad heater THERMOSTAT"
It was probably one of those ones that have no thermostat and just automatically go to a setting that was set at the manufacture, I have one of those on my son's turtle tank.
Are you sure that isn't meant to be used with a controller? If it doesn't have a thermostat then what would determine the temp?
