Thermal Sensor

When checking the thermal sensors, also measure them with the chassis as a reference. If the resistance is
not infinite, the sensor has a short circuit, mostly due to a damaged cable.
If the resistance is infinite, the thermal fuse might be blown. Or in minor cases, check for bad connections at
heater elements and connector.
