I bought a CTC replicator dual clone recently and it was printing perfectly fine for a few days, a few thermocouple problems here and there, but nothing too crazy. But over the past few days the printer will print generally if the print takes less than an hour. It eventually will spike from 220C to 660C and then back down to 220C. It seems that it will display 660C or so for about 1 frame, if it goes for more than 1 frame (screen refresh) it displays tool 0 failure! temperature has met limit, shutdown or reboot.
I’ve taken almost the entire thing apart and put it back together just to receive the same error an hour or two later. Its getting a bit annoying. Any suggestions to clear this up?
Its the replicator dual clone, running sailfish 7.6. The issue happened before I upgraded the firmware, I thought the firmware upgrade would’ve taken care of it, but it didn’t.
Not sure if I’m wording this correct, but sounds like the heat sensor is malfunctioning?

Here is the error message, and here is an example of how long it was printing for. This print was started at around 7am, and failed shortly after 10:20am. Close to 65% complete if I’m not mistaken.

Your thermister or extruder heater is shorted, probably due to a break in the insulation or the wire. You can check to see if it is running to ground with a multimeter. This is either from wear, or as a result of the wire moving over and over again the same way, eventually breaking the wires.
Tool 0 failure shows with either extruder, so you need to check both if you have a dual extruder.
NOW THIS IS IMPORTANT: A short in any of these two (or 4) places can send 24v down the 5v rail, and burn up at least the FETS on the board, or even fry the board. So it is important that you check all this before you turn the printer on.
DO NOT turn the printer on until this is fixed!
