If you know how to use a multimeter (or you have a kind friend who does), you can measure the resistance of the thermistors (temperature sensor), and they should measure approximately 100K ohms at 25C. From there, you can trace the cables, plugs, and wires until you find the broken connection. You can check the resistance of the heated bed or nozzle heater cartridge as well, the bed should measure around 2 to 3 ohms, and the nozzle should measure around 15 to 20 ohms.
