tempature sensor failure?

hello!

awhile ago, i had tried printing and then it had started loudly beeping and displayed a message on the lines of “Nozzle temperature too low”. i cut the power. i turned it back on and tried calibrating it but it gave the error “cr touch error please contact customer service”. also it tells me the nozzle temp is -17. also the printing head is making an odd noise and vibrates slightly.

thank you
