But there is one crucial test you can easily do - with everything powered off measure the resistance across the two pins top left which are the alternative place to plug the thermistor in. The thermistor wires in the ribbon cable are in parallel with these, and so that will measure the resistance of the thermistor through the wires. If all is well you should get a reading of about 6K. This will drop slightly if you put your finger on the thermistor to warm it. If you get a reading of about 10K then the thermistor circuit has a break somewhere.
