Measure the glass plate it should be 3 mm borosilicate glass if not it wil not heat up good as mijn is 3,6 mm glass. my heat bed had broken prints on it and could not heat up.Thy did not replace it now a ntc resistor should be 100kohm but it is 70kohm the temp is not for ABS hot.

Measure the resistance the board's element at room temperature. To reach 110 deg c in a reasonable time at 12 Volts line voltage a resistance must be 1.20 ohms or less 12v boards are specified at 1.0 to 1.2 ohms and must fall into this range to reach 110 deg c in a reasonable time with overhead to 120 deg max. Also ensure your line is 12 volts.
If you buy a new board be sure it meets the resistance specification!!!
