When LCD displays "min error" , you should check if thermistor is well connected or connected to wrong slot. If it is well connected but LCD still displays "min error", you should use a multimeter to check if thermistor is open circuit.

I used a multimeter to test for continuity, and there is no beep. I did this with the printer on and with the printer just connected to usb.

I don't know if we use same type of multimeter, when I use multimeter to check if cricuit is open, there will be beep if cricuit is normal.
So you should check resistance of thermistor, it is about 100k ohm when the temperature is 25°C.
You can test it with printer turned off.

I tested ohms and got around 80, also tested voltage to be 4.7 or so
