Hi everyone i currently have a problem of temperature of the heating head my printer refuses to heat following a value that does not correspond to the reality ex(the nozzle is totally cold but the temperature varies between 148 and 260 °c ) and when I remove the termostat from the nozzle the temperature does not change it and does not indicate a reading error compare to the carpet I have already disconnect and there is an error message Can you give me some leads on the problem my software is up to date but it can come from there the problem occurred due to a long downtime (3 months ) and she had trouble restarting.
Sounds like the Thermistor is bad.
Why was it down for 3 months, it might help to have more info.
