Thermal Runaway Error?
Check out this post here: The screen on my printer is showing a “Thermal Runaway Error”, how do I fix this issue?:
usually this is caused by the printer not reaching temp in time . so the printer is watching if the temperature of the bed or nozzle increases n temperature because it keeps putting the power on until it reaches a set point if it’s not increasing as expected it triggers the thermal runaway protection to keep it from burning your house down. Chances are something has dislodged or damaged the thermister that senses the temperature, if you have done no modifications recently that could be the cause then look for this kind of damage whether it is the bed or the nozzle. could be the sensor the wiring or the motherboard input that causes it. I might just be loose too.
