Sapphire Plus SP-5 bed not working?

Just got my SP-5 today, all set up but no matter what I do the bed shows between 0 and -2 degrees sitting still. Of course, this isn’t right and I am seeing resistance on the thermistor. Bad mainboard?

It’s something related to the thermistor. Double check the connection on the board. Also try swapping the bed thermistor with the hotend thermistor to see if anything changes.

It reads correctly if I do that. Guess I got a bad bed thermistor. Now to see if they can send me a new bed.
