First it gave me an error for the thermocouple out of range, it kept saying the hot end was 360°, I swapped out the hot tends and hit the new one is at 30° but won’t heat up

I know besides the obvious of printing is ASA or ABS is there any sealants that are good for waterproofing PLA? I was thinking on the gorilla spray sealant, would that work ?

My printer broke during a print and it seems like a common thing, can anyone tell me what I have to buy to fix this ?
