Plashforge Creator pro Tool failure and Temperature reads are failing

Hi All, new to the forum and need help. Changed a nozzle in my flash forge creator pro and got a message coming up saying Tool 1 failure Temperature reads failing. https://ome-tv.org/ After a little research, I kept seeing answers saying the thermocouple was broken so I changed https://omegle.website/ it . This hasn't fixed the problem and I am hoping someone can guide me in the right direction as to what it could be. thanks, regards Jord
