Monoprice select mini V2 displaying '999' degrees for build plate temp


I have a monoprice select mini v2, and it has worked well up until now. It currently displays 999 degrees for the build plate temperature. This is a glitch, and I don't know how to fix it. Since it thinks the temperature is so high, it thinks that the build plate does not need to be heated. Because of this, many of my prints turn out warped. Is there a way to fix this?

You get this temperature reading when there is broken wire. Not owning this printer type, can't you switch out the bed thermistor for a new one? Or alternatively check if a connection is loose.
