Curious if anyone has had this happen. I have my tank heater plugged into a hygger temp controller and earlier tonight heard very clearly some electrical noises coming from my office with the tank. Ran in there to the room full of smoke and finally found the culprit. No idea what caused it. At first thought water ran down but no signs of that. Everything is mounted up but it fell during the failure and burned a large mark into my carpet. Luckily didnt do any other damage.
I thought it was the temp controller at first but appears to be the plug for the heater itself that melted.
